Physical erosion by grit entrained in a watercourse will wear away the rock it meets. This why stream boulders typically have a somewhat rounded form.
Chemical weathering occurs when water on the surface of the rock dissolves some of the minerals in the rock matrix. Sometimes, this water solution then dries and the dissolved material crystallizes out in small crevices on the surface of the rock. These crystals may then mechanically disrupt the shape of the crevice as they grow.
Also, if the rock is subject to freeze-thaw cycles, the thermal expansion of the ice may further disrupt the rock fabric.

The major cause of weathering and erosion is?
Wind and water are the major causes of weathering and erosion.
Why people want to stop or control weathering and erosion?
Weathering and erosion cause both physical and monetary damage to property and environmental areas such as buildings and topsoil.
Water causes what type of weathering?
Water causes mechanical and chemical weathering.
Why is physical weathering also known as mechanical weathering?
Physical weathering is caused by elements of nature. It is known as mechanical weathering to distinguish it from the other types of weathering namely chemical and biological. It occurs mechanically, by the breakdown due to natural components.
How does a tornado affect weathering?
Tornadoes do not cause significant weathering, though they can cause localized soil erosion.
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
What are factors that cause physical weathering?
factors that cause weathering are erosion and water
Which can cause physical weathering?
the water erosian and tsumamies and floods
What type of weathering is water?
If you meant weathering that is caused by water; physical weathering is the answer.
Is water freezing in cracks in a rock a physical weathering?
it is a physical weathering.
Does chemical weathering involve water?
Chemical weathering does not involve water, that is physical weathering
Do mountain rocks cause chemical or mechanical weathering?
No, they don't. Rocks don't cause weathering at all. They are the things which get weathered.
How can turtles cause physical weathering?
They loosen the soil and this allows more water to get into the rocks underground
What other thing can cause physical weathering besides the process of thawing and freezing?
water; wind
What can cause physical weathering?
nothing
Is ice a cause of physical weathering?
no
Is a crack that expands because of water physical weathering?
If water freezes in the crack and expands, that would be physical weathering.
