Im not sure but i think its all the above
The answer is the parent material. Parent material is what occurs on the surface before soil begins to form. This is found in new environments such as after a volcanic activity. Pioneers organisms of an ecosystem and abiotic elements of weathering such as water and temperatures begin to weather the rocks into smaller particles, Humus and organic matter from life accumulate with the minute rock particles to form soil over time. The topmost soil is the most developed and this is why soil has profiles towards the deep into the parent rock material, depending on the stage of weathering.
The sahara made migrating rough because it was a desert but it was easier to pass through rather than south afria going through jungles
Answer:
Leeward
Explanation:
Mountains can act as a climatic barrier by blocking prevailing winds and trade winds from getting to the other side of the mountain.
The area that faces the winds is called the windward side. This side receives most of the moisture picked up by the winds from the oceans. This is why it is wetter on this side.
The LEEWARD side is a lot drier because the mountain blocks most of it and as the winds climb up the mountain, most of the moisture is well spent and fall on the windward side. By the time the wind gets to the other side of the mountain, they are dried up already. The <u>leeward</u> side is the area that faces away from the wind.
