windblown loess, like sand, typically accumulates as mound-like dunes.a. true
b. false
The answer is true. Windblown loess, which consists of fine-grained particles, can accumulate in the form of dunes due to the action of wind. Loess dunes are typically smaller and lower in height compared to sand dunes, but they can still have a significant impact on the landscape.
In areas with high winds and limited vegetation, such as deserts and grasslands, loess dunes can be quite common. The formation of loess dunes is influenced by several factors, including wind speed, direction, and the availability of loose particles. Over time, loess dunes can shift and change shape due to the ongoing effects of wind erosion and deposition.

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.

it tends to rain more on the windward side of mountains than the leeward side because:
The reason for more rainfall on the windward side of mountains than the leeward side is because of the georographic effect.
As air rises up the windward side of a mountain, it cools and condenses, leading to the formation of clouds and eventually precipitation. In contrast, as the air descends down the leeward side of the mountain, it warms and dries out, resulting in less rainfall. This phenomenon is known as the rain shadow effect. The leeward side of the mountain tends to be drier and can even be desert-like in some cases. This is because the rising air on the windward side absorbs most of the moisture, leaving little for the leeward side. It's important to note that this effect is not always consistent, and local factors such as topography, temperature, and prevailing winds can also play a role in determining rainfall patterns.

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.

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
b. dew
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.

Which of the following is not a reason for the energy deficit in the polar regions?A) little seasonal variabilityB) low sun angleC) high albedo due to snow and iceD) up to six months without insolation
Low seasonal variability is not a reason for the energy deficit in the polar regions.
The correct option is A.
The energy deficit in the polar regions is mostly caused by the low sun angle, high albedo due to snow and ice, and up to six months of no insolation.
The low sun angle is caused by the tilt of the Earth’s axis, so the sun is never directly overhead in the Arctic and Antarctic regions. High albedo due to snow and ice reflects a large amount of incoming radiation, meaning less is absorbed and converted into heat. The polar regions also experience up to six months without any insolation. This means that the areas receive less solar energy, leading to the energy deficit.

Which plate boundaries is least likely to produce composite volcanoes?
The plate boundary that is least likely to produce composite volcanoes is the divergent plate boundary.
This is because at divergent plate boundaries, the plates are moving away from each other, and as a result, magma from the mantle rises up to fill the gap between the plates, creating new crust. This process results in the formation of shield volcanoes, which are broad and gently sloping, rather than composite volcanoes, which are tall and steep.
In contrast, composite volcanoes are typically formed at convergent plate boundaries, where one plate is forced under another (subduction), causing the magma to rise and create explosive eruptions. Thus, while divergent plate boundaries can still produce volcanic activity, it is unlikely to result in composite volcanoes due to the nature of the plate movement and resulting volcanic activity.
