The process of weathering (the creation of smaller rock particles from a larger rock body), begins as soon as the rock body is exposed to any cause of weathering. The weathering could start immediately in the case of extrusive igneous rock, which is formed from molten material on the surface, when acid in water chemically attacks the surface. Igneous rock underground can begin to weather simply by the erosion of the rock above it, which releases pressure on it, causing the rock body to expand and fracture.
What else can I help you with?
What does a rock begin to do when it is exposed to weather?
When a rock is exposed to weather, it can undergo weathering processes like physical breakdown due to temperature changes, chemical alteration from rainwater or acids, and biological weathering from plant roots or burrowing animals. Over time, these weathering processes can cause the rock to erode and break down into smaller pieces.
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
What does all soil begin as?
All soil begins as rock that is broken down by weathering and biological activity over time.
What effect does weathering have on igneous rock?
The effect of weathering is to reduce the volume of the igneous rock.
Rock formed from the fusion of weathering?
Weathering may change the rock into many shapes.
How does igneous rock changes into sedimentery rock?
By weathering either by physical or chemical weathering.
What kind of weathering is a cracked rock?
It is water weathering
How are weathering erosion and deposition related to the rock cycle?
by weathering
What is the process of rock breaking apart?
It is the process of weathering.
What rock can be changed into sediment by weathering and erosion?
Any and all rock can be changed into sediment by weathering and erosion.
Is ice freezing in a crack of a rock erosion or weathering?
Ice freezing in a crack of a rock is considered weathering.
What is meant by rock weathering?
The process of breaking down of rocks and minerals on the surface is known as rock weathering.
