What is differential weathering?
the difference in degree of discoloration, disintegration, etc., of rocks of different kinds exposed to the same environment.
Which statement best summarizes the process of differential weathering?
Which statement best summarizes the process of differential weathering? Rocks weather at different rates because of differences in their resistance to weathering agents.
Why does differential weathering occur quizlet?
Why does differential weathering occur? Different minerals have different resistances to weathering. If the climate in an area has very little rainfall, what would the characteristics of the soil in the area be?
What is differential weathering in geography?
Weathering that occurs at different rates, as a result of variations in composition and resistance of a rock or differences in intensity of weathering, and usually resulting in an uneven surface where more resistant material protrudes above softer or less resistant parts.
Is differential weathering mechanical weathering?
Mechanical weathering is the process by which rocks are broken down into smaller pieces by external conditions, such as the freezing of water in cracks in the rock. … Differential weathering results when some rocks resist weathering more than other rocks, creating uneven rates of weathering and erosion.
What are the impact of differential weathering and erosion on shaping landforms?
As erosion progresses, by whatever means, some rock units will be more resistant than others. These will be left exposed at higher elevations, and may protect underlying rock.
What is differential erosion?
Erosion that occurs at irregular or varying rates, caused by the differences in the resistance and hardness of surface materials: softer and weaker rocks are rapidly worn away, whereas harder and more resistant rocks remain to form ridges, hills, or mountains.
Which type of weathering is done by animals?
Weathering is the breaking down or wearing away of rocks where they are. It does not happen because they move or collide with each other. One type, biological weathering , is caused by animals and plants.
What are the different types of weathering describe each?
Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments.
