Weathering is the alteration of rocks to more stable material from their exposure to the agents of air, water, and organic fluids. ... Mechanical weathering includes processes that fragment and disintegrate rocks into smaller pieces without changing the rock's mineral composition.
What else can I help you with?
Mechanical weathering caused by rock fragments tumbling against each other is called?
The mechanical weathering caused by rock fragments tumbling against each other is called abrasion. This process can lead to the wearing down and smoothing of the rock surfaces involved.
Are all wathered rock fragments all the same size why or why not?
No, weathered rock fragments can vary in size depending on the type of weathering that occurs. Mechanical weathering can break rocks down into different sizes, forming a mixture of small and large fragments. Chemical weathering can also cause rocks to disintegrate into varying sizes based on the mineral composition and the intensity of the weathering process.
What is a layer of rock and mineral fragments produced by weathering?
A layer of rock and mineral fragments produced by weathering is called sediment. Sediment is formed when rocks are broken down into smaller pieces by physical, chemical, or biological weathering processes, and then these fragments are transported and deposited by water, wind, or ice. Over time, these sediment layers can become compacted and cemented together to form sedimentary rocks.
How does rock become changed into topsoil?
Rocks are broken down into smaller pieces by physical weathering processes like wind and water erosion. Over time, organic matter from plants and animals accumulates on the rock fragments, breaking them down further. The combination of rock fragments and organic matter eventually forms topsoil through the process of weathering and decomposition.
What is is The layer of rock and mineral fragments produced by weathering and covering nearly all of earths land surface called?
The layer of rock and mineral fragments produced by weathering and covering nearly all of Earth's land surface is called regolith. Regolith is made up of various sizes of rock and mineral particles that result from the breakdown of bedrock over time due to weathering processes.
Weathering and erosion break rock into?
fragments
What are the rock fragments resulting from freeze thaw weathering?
These are known as scree or talus.

What are two reasons why weathering is important?
Because it breaks rock down into fragments and layers. By Kayla

Does erosion break down rock into fragments where as weathering transports those fragments?
No:Weathering is the wearing away/breaking down of rock into fragments IN SITUErosion is the wearing AND TAKING AWAY of materialAlso note that the transportation of fragments is just transportation, so don't bother searching for a fancy term for it.
What are loose rock fragments?
Loose rock fragments can be caused by weathering, or indeed erosion. They can be found in a scree slope, and alluvial fan, a beach, in the soil (they are the soil, sometimes). Loose rock fragments are known to a geologist as 'Unconsolidated sediment' which can be classified into various groups. Consider alluvium; the deposit from a river.
The rock and mineral fragments in soil come from rock that has been?
The rock and mineral fragments in soil come from the breakdown of parent rock through processes like weathering and erosion. Over time, physical, chemical, and biological factors contribute to the decomposition of rocks into smaller fragments that make up soil.
The process that breaks down rock and other materials at earth's surface is called?
The process that breaks down rock and other materials at Earth's surface is called weathering. Weathering can occur through physical processes like freezing and thawing, as well as chemical processes like oxidation and hydrolysis.
