The Amazon had an unusual drought that reached its peak in 2005, resulting in almost record-low streamflows, a minor Amazon river plume, and significantly increased fire frequency.
El Nino in the years 2002–2003 and a dry spell in 2005 brought on by a warm subtropical North Atlantic Ocean were both contributing factors in drought. Conditions became drier as tributaries dried up and forest fires spread, killing enormous numbers of trees needed to create rainfall.
The drought created food shortages for thousands of people, issues with river transportation, agricultural production, and hydroelectricity generation, as well as direct and indirect effects on the communities residing along the region's rivers.

jack hall (dennis quaid) is a climatologist studying the effects of global warming. why is he taking ice core samples from antarctica? what does this have to do with global warming?
Since Jack hall is studying the effects of global warming. the effect that ice core samples tell about global warming is that Ice cores offer immediate information on past changes in greenhouse gas concentrations as well as direct proof that the climate can shift suddenly in certain situations.
What do ice core samples in Antarctica reveal about global warming?As tree rings are to trees, so are ice cores to ice sheets. Ice cores reveal information about ice sheets in a same way that tree rings do for trees. Jack was collecting ice core samples from Antarctica so that scientists could examine the chemistry and make-up of earlier climates.
To investigate the glacial and interglacial periods, ice cores have been employed. Debris and chemicals are naturally preserved by the ice and snow.
Therefore, Note that Climate scientists examine greenhouse gas concentrations in ice core layers to reconstruct historical climates. Scientists can compute how current carbon dioxide and methane concentrations compare to historical ones.

charcoal from a hearth site in colorado, 2,000 miles south of alaska, is known to be 11,200 years old. researchers reasoned that, since glaciers prevented human migration south from the alaska-siberia land bridge between 18,000 and 11,000 years ago, humans must have come to the americas more than 18,000 years ago.
The majority of scientists agree that a single wave of people arrived in Alaska from Siberia around 13,000 years ago across a long-gone land bridge.
What became of the land link connecting Siberia and Alaska?
At its greatest length, the land bridge was nearly 1,000 miles long from north to south. When the glaciers melted at the end of the Ice Age due to climate change, Beringia was flooded approximately 10,000–11,000 years ago, severing the land bridge. By 6,000 years ago, coastlines were roughly where they are now.
When did the geographical connection between Alaska and Siberia vanish?
Around 13,000 years ago, the last ice age ended and the land bridge started to submerge into the water. As the massive continental ice sheets melted and released billions of gallons of fresh water, global sea levels surged.

∠ABD will be 40 degrees in the provided question.
Describe an angle.When two rays or straight lines intersect at one of their ends, an angle is created. Vertex of an angle refers to the point at which two points meet. The Latin word "angulus," which means "corner," is the origin of the English term "angle."
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These are referred to as dihedral angles.
In the given question,
As ∠ABC given = 85°

People prefer to live along the coastlines and large rivers because they provide them with fertile soil, thus food production, pleasant climate, easy transportation of goods, easy traveling, good connectivity, etc.

Answer:
fertility playes vital role in distribution of population
Geographical or Physical factor plays a vital role in the distribution of population.
Population distribution refers to the spatial pattern caused by population dispersion, agglomeration creation, linear spread, etc.
High population densities are typically found in lowland plains, flat river basins and deltas, and volcanic regions with good soil. Low population densities are typically seen in mountainous regions with steep slopes and poor soil. Compared to areas that experience more extreme weather and temperatures, temperate zones attract more people. People tend to be more concentrated in areas with a moderate climate that has evenly distributed rainfall or a monsoon-like climate than in areas that are highly dry, severely cold, or extremely wet.The availability of water is vital for human survival and development, therefore regions with enough water (but not too much) tend to have denser populations than those that are dry or frequently experience drought, or those that receive an excessive amount of rainfall or may be vulnerable to flooding.Learn more about Population Density here:

Some portions of the shoreline may recede more quickly than others due to variations in the resistance of the rocks to erosion. This will develop gradually along a dissonant shoreline;
Briefing: -Eventually there will be headlands that stick out into the sea and bays where the land has been worn back, as seen in the figure. Beaches develop at the innermost part of a bay, as seen in the figure. Over thousands of years the softer less resistant-rock is eroded more quickly than the harder more resistant rock and differences will become more pronounced.
In this region, deposition takes place and wave action is typically not particularly vigorous.

Since his shadow is so faint when he is at the equator, it is clear that the sun's rays are falling vertically.
Due to two processes, a shadow starts to take on increasingly greater shades as the individual raises his latitude:
Since the earth is spherical, there is an area where the sun cannot be seen because of the angle created by the normal to the earth's surface and the sun's ray.The inclination of the Earth concerning the sun varies throughout the year.The shadow should be infinite when the subject is directly over the north pole, indicating that they are parallel to the sun's rays.

The correct answer is option D: the change from fresh snow to firn and then to glacial ice
The change from fresh snow to firn and then to glacial ice best describes the snow metamorphosis.
The transformation of the snow crystals gradually over time is called snow metamorphosis.
From the moment the snow crystals fall on mountains or the earth's surface they begin to metamorphose i.e. the process of ice formation.
When the granules of fresh snow called firn fall over the old snowpacks, the shape, size, and form of the snow crystals keep changing over time, and eventually, firn transforms into solid glacier ice within a period of one year.

Answer: The larger the surface area the easier it is for the soil to hold onto water so it has a higher water holding capacity
Explanation:
Because soil can absorb twice it size in water
Answer:
It depends on soil texture and organic matter.
Explanation:
organic matter, compaction, and salt concentration of the soil. Organic matter increases a soil's ability to hold water, both directly and indirectly. When soil is at field capacity, organic matter has a higher water-holding capacity than a similar volume of mineral soil.
