Soils vary throughout the world. Climate, elevation, plant growth; these are just some factors that influence weathering and soil formation. This is a mountain in Canada. It is located in the taiga. Notice the large rocks rolling down the side of the mountain. Weathering will eventually break down these rocks into smaller particles that form soil.
Think about the biome: the taiga. Look at the picture. Predict what the major agents of weathering are in this area.
A) freezing and thawing; tree roots
B) gravity, lichens and moss, tree roots
C) tree roots, lichens and moss, freezing and thawing
D) rushing river water, glacial ice, freezing and thawing

B) gravity, lichens and moss, tree roots

Explanation:

In this mountainous area of Canada, weathering of rocks occur due to the force of gravity which increases the speed of rolling rocks and causes weathering of rocks into small pieces. These rocks have hard surfaces so only moss and lichens grow on these surfaces. The reason behind the growth of moss and lichens is that they have not specialized root system like plants. Lichens also helps in the weathering of these rocks by secreting chemicals.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
