Answer: a. Dendritic
Explanation:
A dendritic drainage pattern is the most common form and looks like the roots of trees branching pattern. It is a drainage pattern in which streams branch in many directions randomly at different angles as well. It develops in regions that have underlying homogeneous material. This means the subsurface geology has a similar resistance to weathering resulting in no seeming control over the direction the tributaries take. It is produce in streams that receive several tributaries that are fed by smaller ones. Tributaries link up a larger stream at acute angle ( angle less than 90 degrees). It can be indicated when streams flow across horizontally and complex crystalline rock/homogeneous strata help in resisting erosion uniformly.
Jose San Martin was an argentine general and the prime leader of the southern part of south America. hoped that helped!
Answer:
Glacial retreat occurs when ice melts faster than it forms.
Explanation:
Glaciers are large, slow-moving masses of land ice formed by the recrystallization of snow. For complex reasons, if the worldwide climate becomes cooler, and snow accumulates faster than it melts, the glaciers grow larger and cover more land. 10% of the Earth's surface today is covered by glaciers. Antarctica and Greenland are virtually covered by glaciers. At the height of past glacial ages, 32% of the Earth was covered by glacial ice. Most of Chicago is covered by glacial or glacial-related deposits.
Greenhouse (warm) periods: extensive and prolonged volcanic activity produces excessive carbon dioxide Thus based on above the glaciers have been melted in the recent past and still continue.
Apart from this, the climate will cool again at the end of global warming and climate change. The natural cycle will change and raising the carbon content along with sea levels.
