What weathering affects granite?

Chemical weathering of granite occurs when dilute carbonic acid, and other acids present in rain and soil waters, alter feldspar in a process called hydrolysis.

Which is the best example of physical weathering?

Pressure, warm temperatures, water and ice can cause physical weathering. Physical Weathering in NatureWhen water in a river or stream moves quickly, it can lift up rocks from the bottom of that body of water. When the rocks drop back down they bump into other rocks, and tiny pieces of the rocks can break apart.

What is the most important type of weathering in warm humid environments?

In humid and warm regions, chemical weathering is the dominant type of weathering. Landforms tend to be more rounded and soils tend to be thicker.

In what environment would weathering rate be fastest?

Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates. Without temperature changes, ice wedging cannot occur.

Which rock type is most resistant to weathering?

Igneous rocksIgneous rocks are usually solid and are more resistant to weathering. Intrusive igneous rocks weather slowly because it is hard for water to penetrate them. Sedimentary rocks usually weather more easily. For example, limestone dissolves in weak acids like rainwater.

What is it called when softer rocks wear away and leave harder rocks behind?

differential weathering is called when softer rocks wear away and leave harder rocks behind.

What part of the mountain weathers the fastest?

Slope The steep sides of mountains and hills make water flow down them faster. Fast-moving water has more energy to break down rock than slow-moving water. Therefore, rocks on steep slopes can weather faster than rocks on level ground. 5.

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.

What are the four main types of weathering?

There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.

How does surface area affect the speed of weathering?

How does surface area affect the rate of weathering? 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.

What are the 4 factors that affect the rate of weathering?

Which rock type is the most resistant to erosion?

Metamorphic rocks are highly resistant to erosion and are often used in building materials.

What are the two most important factors that determine the rate of weathering?

The most important factors that determine the rate at which weathering occurs are the type of rock and the climate.

What type of rock weathers the fastest?

limestoneThere are some rocks, like limestone, that weather more rapidly. Limestone has the compound calcite. It is the carbonization of calcite that causes the increased rate of weathering of limestone. The material found in sediment grains also affects the rate of weathering.

What are the 3 factors that affect 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. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.

What are the two factors that affect the rate at which weathering occurs?

There are two factors that play in weathering, viz. Temperature and Precipitation. Warm climates affect by chemical weathering while cold climates affect by physical weathering (particularly by frost action). In either case the weathering is more pronounced with more moisture content.

When the surface area increases the rate of weathering?

The rate of weathering increases because the surface area-to-volume ratio of the small rocks is greater than that of the large rock. So, a greater proportion of a smaller rock is exposed to weathering processes. Figure 2 shows this concept in detail.
