When the surface area increases the rate of weathering will?

How does surface area affect weathering rate?

How Does a Rock’s Surface Area Affect Weathering? Most chemical weathering takes place only on the outer surface of a rock. Therefore, rocks with a lot of surface area weather faster than rocks with little surface area. … In the same amount of time, the smaller rocks weather more and become much smaller.

What increases the rate of weathering?

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. … Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.

How can increasing the surface area of a rock speed up the process of weathering?

Mechanical weathering increases the overall surface area when it breaks down the rock into smaller fragnments. Increased surface area provides more surface for chemical weathering to attack the rock, allowing chemical weathering to speed up.

How does surface area affect the rate of weathering quizlet?

When the amount of surface area relative to volume increases, the rate of weathering increases. … weathered it can increase the surface area of the rock. This means that more of the rock is exposed to chemical weathering. Therefore, the rate of chemical weathering will increase.

How does surface area contribute to weathering of a rock?

1. Surface area — if the rock is broken down into small pieces, it undergoes chemical weathering more readily than does one large piece. Smaller pieces have more surface area for water and gases to react with the rock. Mechanical weathering is effective at increasing surface area.

How does physical weathering change the surface area of rocks and affect the rate of chemical weathering?

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.

Which of the following activities has resulted in an increased rate of weathering?

Humans cause increases in acid rain and pollution, which increase the amount of weathering agents in the air and water, and then on land.

How does time affect the rate of weathering?

The process of weathering is a time taking process. The duration of time for which a rock is exposed to weather determines the extent of weathering. Very strong rocks, however strong they might be will severely undergo weathering in hundreds of years.
