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.
What else can I help you with?
The major cause of weathering and erosion is?
Wind and water are the major causes of weathering and erosion.
Water causes what type of weathering?
Water causes mechanical and chemical weathering.
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.
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.
Explain whether water is a cause of either chemical weathering physical weathering or both?
Water can cause both chemical and physical weathering. In chemical weathering, water can react with minerals in rocks to break them down into new substances. In physical weathering, water can seep into cracks in rocks, freeze, and expand, creating pressure that breaks the rock apart.
Which can cause physical weathering?
the water erosian and tsumamies and floods
What are factors that cause physical weathering?
factors that cause weathering are erosion and water
What is the most active agent of physical weathering?
The most active agent of physical weathering is water. Water can seep into cracks in rocks, freeze, expand, and cause the rock to break apart. This process is known as frost wedging and is a common form of physical weathering.
How does a gopher cause weathering?
Gophers cause physical weathering. They dig burrows in the ground, allowing more rock to be exposed.
How can turtles cause physical weathering?
They loosen the soil and this allows more water to get into the rocks underground
What can cause physical weathering?
nothing
Is ice a cause of physical weathering?
no
What of these does not cause physical weathering?
Chemical weathering does not cause physical weathering. Chemical weathering refers to the breakdown of rocks through chemical reactions, while physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.
Can earthworms cause physical weathering?
not really.
Which is a cause of mechanical weathering?
physical forces
