What is the fastest weathering?

Which rock weathers most quickly?

Rocks also weather differently. Igneous 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.

What type of weathering is slow?

Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. … slow down they can’t carry as much sediment.

What type of weathering happens the most?

Mechanical weathering

This type of weathering does not change the minerals that make up a rock. It just breaks them into smaller pieces. Mechanical weathering is most common in cold, dry climates.

What speeds up mechanical weathering?

– Weathering depends on water and temperature. – Mechanical weathering occurs fastest in areas that have a lot of temperature changes. – Chemical weathering is fastest where the climate is warm and wet, near the equator.

Which rock is least resistant to weathering?

Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.

What is the most powerful eroding force?


But the most powerful erosive force on earth is not wind but water, which causes erosion in its solid form — ice-and as a liquid. Water in its liquid form causes erosion in many ways. Streams — from tiny creeks to huge rivers — carry tons of eroded earth every year.

Which area would most likely have the fastest rate of chemical weathering?

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.

Why does weathering occur faster in a hot climate?

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. This happens because plants and bacteria grow and multiply faster in warmer temperatures.
