How does the surface area of a rock affect the rate at which it weathers Brainly?

How does the surface area of a rock affect the rate it is weathered?

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.

What is surface area and how does it affect the rate of weathering?

The larger the surface area-to-volume ratio of a rock is, the faster the rock will wear down. Chemical weathering occurs faster in warm, wet climates than in hot, dry climates. Rates of weathering are affected by elevation, by the slope of the ground, and by living things.

What factors influence the rate of weathering Brainly?

Rainfall, heat and moisture are the 3 main factors which affect the rate of weathering and soil erosion. Weathering happens more quickly in hot and wet climates.

When a rock increases surface area?

When surface area of a rock is increased, the rock is less vulnerable to chemical weathering. the rock is less vulnerable to physical weathering. the rock weathers less rapidly because fewer surfaces are exposed.

How does the surface area of the rock and temperature affect weathering?

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 the climate and rock type affect how quickly a rock weathers?

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.

What is the correlation between surface area and rate of weathering quizlet?

What is the correlation between surface area and rate of weathering? The greater the surface area, the more rock is exposed so the faster the weathering.

Which type of weathering increases the surface area of a rock group of answer choices?

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. 12.

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.

How does weathering affect the rock cycle?

Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth’s surface breaks down rocks into small and smaller pieces. … If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock.

What are the 3 factors that affect the rate of weathering?

Rocks that are fully exposed to the atmosphere and environmental elements, such as wind, water and temperature fluctuations, will weather more rapidly than those covered by ground. Another factor that affects the rate of weathering is the composition of rock.
