What else can I help you with?
Lichens and moss can cause chemical weathering when they give off what?
acid
How can lichens cause mechanical weathering?
they eat away the surface of a rock
Contact of a rock with mosses and lichens is an example of this type of weathering?
Biological weathering. Mosses and lichens are organisms that can break down rock surfaces through their root systems and by secreting acids that can dissolve minerals in rocks, leading to their weathering and erosion over time.
What are three cause of weathering of the lithosphere?
Three causes of weathering of the lithosphere are physical weathering, which includes processes like frost action and plant roots breaking up rocks; chemical weathering, which involves chemical reactions that weaken or dissolve rocks; and biological weathering, where organisms like lichens and bacteria contribute to rock breakdown.
What most common cause of chemical weathering?
The most common cause of chemical weathering is oxygen
What is most common cause of chemical weathering?
The most common cause of chemical weathering is oxygen
Contact of a rock with mosses and lichens is an example of what type of weathering?
Contact of a rock with mosses and lichens is an example of biological weathering, where living organisms break down the rock through their physical or chemical actions. The roots of mosses and lichens can penetrate cracks in the rock surface, causing it to break down over time.
Do acids cause mechanical weathering?
No, acids cause chemical weathering.
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
Which is an agent of chemical weathering that produces weak acids that dissolve rock?
By burrowing animals like Lichens.
Are common organisms that grow on rock and cause weathering?
Lichens are common organisms that grow on rock and contribute to weathering through their physical and chemical actions. Lichens produce acids that can break down rock material, facilitating the process of weathering over time. Their presence can help break down rocks into smaller particles, contributing to soil formation.
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.
