How can earthworms cause weathering?
Earthworms cause weathering by ingesting soil and organic matter, breaking it down in their digestive system, and then excreting it as castings. These castings are rich in minerals and nutrients that can react with the soil, promoting chemical weathering processes. Additionally, earthworm burrowing activities can create pathways for water to infiltrate the soil, accelerating physical weathering processes.
How might a earthworm cause physical weathering?
Earthworms can cause physical weathering by burrowing through soil, which can create tunnels that allow air and water to penetrate deeper into the ground. As they move through the soil, earthworms can also push rocks and sediment to the surface, exposing them to the elements and contributing to the breakdown of rocks through processes like frost wedging.
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
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.
What can cause physical weathering?
nothing
Is ice a cause of physical weathering?
no
How do earthworms aid in weathering?
The answer is that earthworms help to build soil and fertilize
Which is a cause of mechanical weathering?
physical forces
How can pocket gophers cause physical weathering?
By digging deep holes in the ground and breaking up rocks.
Is desert pavement cause by chemical weathering?
No, desert pavement is caused by wind which is physical weathering.
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.
What are factors that cause physical weathering?
factors that cause weathering are erosion and water
