The upstream country that could control the flow of the Nile River into Egypt is Ethiopia.
Ethiopia is the source of the Blue Nile, which is one of the two main tributaries that merge to form the Nile River. Ethiopia is currently constructing the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile, which has caused tensions between Ethiopia and downstream countries, particularly Egypt. Egypt is concerned that the GERD could significantly reduce the flow of the Nile River into Egypt, which would have serious consequences for its water and electricity supply. Ethiopia, on the other hand, argues that the GERD is essential for its economic development and energy security. Negotiations between Ethiopia, Egypt, and Sudan to resolve the issue have been ongoing for years, but a final agreement has not yet been reached.

One of the best ways to mitigate subsidence in the SF Bay Delta is to increase water storage in upstream reservoirs.
This would allow for more water to be released during the dry season and reduce the amount of water drawn from the Delta. It would also help prevent saltwater intrusion and reduce the amount of sediment and pollutants entering the Delta.
In addition, improving water conveyance infrastructure such as levees and canals can help reduce subsidence by allowing more water to be transported around the Delta and into reservoirs. Other measures, such as reducing groundwater pumping, restoring wetlands, and preventing agricultural runoff, can also help to reduce subsidence.

the berlin wall and the mexican border are good examples of ________ boundaries.
The Berlin Wall and the Mexican border are examples of physical boundaries.
Physical boundaries, also known as natural or geometric boundaries, are formed by physical features such as walls, rivers, mountains, or coastlines. These boundaries separate one territory from another and can have significant political, social, and cultural implications. The Berlin Wall, which divided East and West Berlin from 1961 to 1989, and the Mexican border, which separates Mexico and the United States, are both examples of physical boundaries.
The Berlin Wall was constructed during the Cold War and was intended to separate East Germany, which was under Soviet control, from West Germany, which was aligned with Western powers. The wall physically divided the city of Berlin and served as a symbol of the ideological divide between the Eastern Bloc and the Western Bloc.
Similarly, the Mexican border with the United States is a physical boundary marked by fences, walls, and natural barriers like rivers and deserts.

mineral evidence suggests that on earth, the oceans first formed as early as
Mineral evidence suggests that on earth, the oceans first formed as early as 4.4 billion years ago.
The formation of both the earth and oceans are intricately linked and occurred simultaneously through a process called accretion. Accretion is the gradual accumulation of matter by gravity, which led to the formation of our planet and its surrounding bodies.
During the early stages of accretion, the earth was extremely hot and molten, with temperatures exceeding 5,000 degrees Celsius. This heat caused the minerals that made up the earth's crust to vaporize and form a thick atmosphere of water vapor, carbon dioxide, and other gases.
Over time, as the earth cooled, the water vapor in the atmosphere began to condense and form liquid water on the surface. The mineral evidence suggests that this process started as early as 4.4 billion years ago, with the formation of the first oceans.
The mineral evidence comes from the discovery of ancient rocks that contain tiny mineral grains known as zircons. These zircons have been dated back to 4.4 billion years ago and show evidence of having been formed in the presence of liquid water.
Overall, the formation of the earth and oceans are closely intertwined and have been shaped by a complex set of processes that have occurred over billions of years. The mineral evidence provides a window into the early history of our planet and helps us to understand how it has evolved over time.

in the df and dw climates, winter precipitation mainly originates from ________.
In the df and dw climates, winter precipitation mainly originates from cyclonic systems.
In the df (dry-summer subtropical) and dw (dry-winter subtropical) climates, winter precipitation is mainly generated from frontal systems that move in from the adjacent oceans, such as the Atlantic and Pacific Oceans. These fronts carry moisture in the form of rain and snow, which are released when the fronts interact with the landmass of the region.
In addition, the winter season is often accompanied by a large amount of atmospheric instability, which can lead to the formation of thunderstorms and other convectional precipitation. Furthermore, some areas in the df and dw climates experience winter precipitation from the continental polar air mass, which is a cold and dry air mass that originates from the interior of the continent.

Why will an iron-rich olivine have a higher density than a magnesium-rich olivine?
a) Iron has a greater atomic mass than magnesium and therefore is heavier.
b) Magnesium-rich olivine has more silicon, which is less dense.
c) More magnesium is needed to equal the same atomic charge as iron.
d) Iron-rich olivine has smaller crystals, so more of them will fit into the same area.
The correct solution is a) Iron has a greater atomic mass than magnesium and therefore is heavier.
The density of a substance is determined by its mass per unit volume. Since iron has a higher atomic mass than magnesium, it means that individual iron atoms are heavier than individual magnesium atoms. When iron substitutes for magnesium in olivine, the iron-rich olivine will have a higher overall atomic mass, resulting in a higher density compared to magnesium-rich olivine.
The presence of silicon in olivine, as mentioned in option b), does not significantly impact the density difference between iron-rich and magnesium-rich olivine. Similarly, options c) and d) are not correct explanations for the density difference.

the kalahari desert located in southern africa is located between 20°-30°s latitude is classified as ________ desert.
The Kalahari Desert, located in Southern Africa, is situated between 20°-30°S latitude and is classified as a trade wind desert.
Trade wind deserts are formed as a result of consistent wind patterns, specifically the trade winds, which blow from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere. These winds are responsible for the desert's arid conditions.
In the case of the Kalahari Desert, its location within the subtropical high-pressure belt plays a significant role in its climate. The belt is characterized by descending air masses that result in high pressure at the surface, leading to minimal cloud formation and limited rainfall. The Kalahari experiences relatively low precipitation levels, averaging around 100-500mm per year, which contributes to its desert classification.
Another factor influencing the Kalahari Desert's aridity is the presence of the Benguela Current along the southwestern coast of Africa. This cold ocean current cools the air above it, reducing its ability to hold moisture and creating stable atmospheric conditions. This prevents the formation of clouds and further decreases rainfall over the desert.
In conclusion, the Kalahari Desert's classification as a trade wind desert is primarily due to its location within the subtropical high-pressure belt and the influence of the trade winds. These factors, combined with the impact of the Benguela Current, contribute to the desert's arid conditions and low precipitation levels.

Which of the following is not considered to be a form of precipitation?
Answer
a. rain

c. snow
Precipitation refers to the process in which condensed water vapor in the atmosphere falls back to the Earth's surface. Rain and snow are both examples of precipitation.
Rain is the most common and well-known form of precipitation. It occurs when water droplets in clouds combine and become heavy enough to fall to the ground. Rain can be in the form of drizzle, showers, or storms, and it occurs when the temperature is above freezing. Snow, on the other hand, is precipitation in the form of ice crystals. It forms when the temperature in the atmosphere is below freezing, and water vapor directly transforms into ice without passing through a liquid phase. Snowflakes are formed by the aggregation of ice crystals in the clouds and then fall to the ground. Dew, however, is not classified as precipitation. It forms when the surface cools down during the night, causing the air near the surface to cool as well. As the air cools, it loses its capacity to hold moisture, leading to condensation on surfaces such as grass, leaves, or other objects While it is related to atmospheric moisture, dew is not considered a form of precipitation because it does not involve water falling from the atmosphere to the ground like rain or snow.

dsecribe the process of upwelling and explain why el nino conditions suppress upwelling off the west coast of south america
Answer:
El Nino is a phenomenon that influences weather. Due to differential heating of ocean surface water a large swathe of warm ocean water is formed in the Pacific Ocean Equatorial region. The swathe of comparatively cold water in the vicinity of El Nino is referred to as La Nina-. Bother of these phenomenon have no direct relationship with flood.
Well seasonal torrential rains are responsible for floods. Floods are part and parcel of nature. It is we the human beings who interprete them as calamity.
To mitigate our losses (????) The only avaible option is to arrest the flood water so that it doesn't flood our settlements, agricultural ventures and assets of economic interest. This applies to all types of floods.
We can build dams across the rivers so the sudden excessive rain water inflow can be retained in the upstream reservoirs.
The other option is do not utilise flood plain lands for any of our activities. Flood plains are low lying trough like land parcels adjoining the rivers. They are prone to flooding with seasonal increase in water inflow.
Unfortunately these lands are very fertile and so since centuries have been aggressively utilised to satiate our agricultural interests. Over a period agriculture initiates human settlement. This is the reason why floods cause massive destruction.
Flood plains are a nature's way to hold excessive water. Flood plains sustain biodiversity.
Why does water heat up more slowly and to a lower temperature than a comparable area of land surface, when both receive the same amount of energy from the Sun?A. Water stores heat in a non-sensible form.B. Water is opaque to sunlight.C. Less water evaporates from the water surface.D. Heat is more mobile in water.E. Water has a lower specific heat.
Water has a lower specific heat. Specific heat is the amount of energy required to raise the temperature of a given mass of a substance by one degree Celsius.
The answer is E.
Water has a much lower specific heat than land, meaning that it takes less energy to raise the temperature of a given mass of water by one degree Celsius.
This means that even when exposed to the same amount of energy from the Sun, the temperature of water will rise much more slowly than the temperature of a comparable area of land surface. As a result, the arctic ice cap is able to remain frozen even in the presence of high amounts of energy from the Sun.

when a tornado is just about to form, what happens right before a tornado hits the ground?The air takes a "rolling pin" formationA tornado can descend from the mesocycloneSurface winds slow due to ground frictionThe rolling air takes a vertical axis
Before a tornado hits the ground, a few things happen. Firstly, the air takes on a "rolling pin" formation, which means that the wind starts to rotate horizontally.
This rotation happens because of the mesocyclone, which is a rotating updraft that forms within a thunderstorm. As the mesocyclone starts to descend, it pulls the rotating air down with it. Secondly, surface winds begin to slow down because of friction with the ground. This means that the air that is rotating starts to take a more vertical axis, which is necessary for the formation of a tornado. As the rotation becomes more vertical, a funnel cloud starts to form. Once the funnel cloud reaches the ground, it becomes a tornado. It is important to note that tornadoes are unpredictable and can form quickly, so it is always best to take shelter as soon as you hear a tornado warning.

These layers build up over time as the volcano erupts repeatedly. The steep, upper slopes of composite volcanoes are primarily shaped by the deposition of these materials. When lava erupts from the volcano's vent, it flows down the slopes, gradually cooling and solidifying to form hardened layers. The volcanic ash, which consists of fine fragments of rock and volcanic debris, is also ejected during eruptions and settles on the slopes, contributing to the buildup of material. Over time, the repeated accumulation of these layers of solidified lava flows and volcanic ash results in the characteristic steepness of the upper slopes of composite volcanoes.
