What is the main factor that causes the bedrock to weather at different rates?
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering.
How does climate affect weathering?
So how do different climates influence weathering? A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering.
Which type of weathering occurs more rapidly in a cold climate?
Mechanical weathering
Mechanical weathering is more rapid in cold climates. This is because of frost shattering. Water seeps into tiny cracks in the rocks.
Which rock will weather the fastest when exposed to acid rain?
Ero/Dep review 1
| Question | Answer |
|---|---|
| Which rock weathers most rapidly when exposed to acid rain (calcite) | limestone |
| Which change in climate would most likely cause the greatest increase in chemical weathering of local bedrock? | more rain |
| Which factor has the most influence on the development of soil? | climate |
Why will a rock weather faster after it has been crushed?
Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases figure 5. With more surfaces exposed, there are more surfaces on which chemical weathering can occur. Mechanical weathering may increase the rate of chemical weathering.
Why does chemical weathering occur in moist climate?
Chemical weathering occurs in moist and cold climates. It is because moist climates cause minerals in rocks to either dissolve in water or change their composition.
Does humidity increase weathering?
New study by University of North Carolina confirms that increased humidity in air and rising temperatures leads to rocks weathering faster.
How does rock composition affect weathering?
Another factor that affects the rate of weathering is the composition of rock. The presence of iron in rocks causes them to weather more quickly and break apart more easily. Some minerals are softer than others, and therefore rocks that contain these minerals will weather more rapidly.
How does the texture of a rock surface affect how fast it physically weathered by water?
The material found in sediment grains also affects the rate of weathering. A rock’s exposure to the weathering elements and its surface area can affect its rate of weathering. Rocks that are constantly bombarded by running water, wind, and other erosion agents, will weather more quickly.
