Chemical weathering rocks may decompose or dissolve and at the same time change in compostion through a certain chemical process to form residuals materials. Mechanical weathering happens when rocks disintegrate or breaks down into smaller pieces through physical forces. (rain, snow, freezing)

How to explain weathering?
Weathering is the process by which rocks and minerals are broken down into smaller pieces through exposure to natural forces like water, wind, and temperature fluctuations. There are two main types of weathering: mechanical weathering, which involves physical breakdown of rocks into smaller fragments, and chemical weathering, which involves chemical reactions that alter the composition of rocks. Over time, weathering can contribute to the formation of soil and shape the Earth's surface.
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.
Explain the similarities and difference between physical weathering and chemical weathering?
Physical weathering involves the breakdown of rocks into smaller fragments without altering their chemical composition, typically through processes like freezing and thawing or abrasion. Chemical weathering, on the other hand, involves the decomposition of rocks through chemical reactions that change their composition, such as oxidation or dissolution by acidic water. Both processes contribute to the overall breakdown of rocks, with physical weathering primarily affecting the size and shape of rocks, and chemical weathering changing their chemical structure.
Explain the steps involved in breaking down mountain rock?
The steps involved in breaking down mountain rock is called weathering. Weathering takes place naturally and is caused by wind, rain, ice, snow, and rivers. This breaks rocks into large pieces that continue to break down.
What statement is best to explain the process results in weathering?
Weathering is the process where rocks and minerals are broken down into smaller pieces through various physical, chemical, or biological processes. These smaller pieces can then be further eroded and transported by natural forces like wind, water, or ice. Over time, weathering can transform solid rock into sediment and contribute to the formation of soil.
Explain the difference between mechanical and chemical weathering?
Mechanical weathering is the breakdown of rocks into smaller pieces without altering their chemical composition, usually by processes such as frost wedging or root expansion. Chemical weathering, on the other hand, involves changes in the chemical composition of rocks due to reactions with substances like water, acid rain, or oxygen, leading to the breakdown of minerals.

Explain how plants can act as agents of both mechanical and chemical?
Plants can act as agents of mechanical weathering through root growth that exerts pressure on rocks, causing them to break apart. They can also contribute to chemical weathering by releasing acids or organic compounds that break down minerals in rocks over time. These processes can help break down rocks and contribute to soil formation.

Explain the difference between chemical and physical weathering?
Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution. Physical weathering, on the other hand, occurs when rocks are broken down into smaller pieces through physical processes like freezing and thawing, or abrasion. Chemical weathering changes the composition of the rock, while physical weathering only breaks the rock into smaller pieces.

What is the process of rocks breaking down into smaller pieces explain 2?
One process is physical weathering, where rocks are broken down by mechanical forces like freezing and thawing, or by abrasion from wind and water. Another process is chemical weathering, which involves the breakdown of rocks through chemical reactions such as oxidation or hydrolysis. Both processes contribute to the gradual breakdown of rocks into smaller pieces over time.
How do you explain the three types of weathering?
That is something that would show up in bold print in your text book. It's not stupid. physical chemical biological Physical weathering breaks rocks down into smaller pieces. Types of physical weathering include frost wedging, exfoliation, and thermal expansion. Chemical weathering breaks rocks down chemically adding or removing chemical elements, and changes them into other materials. Chemical weathering consists of chemical reactions, most of which involve water. Types of chemical weathering include: dissolution hydrolysis oxidation Biological weathering is the breakdown of rock caused by the action of living organisms, including plants, burrowing animals, and lichen (a crusty, rubbery, light green organic material that grows in patches on rocks as well as on wood). Lichen is a combination of fungus and algae, living together in a symbiotic relationship. Lichens can live on bare rock, and they break down rocks by secreting acids and other chemicals. The fungal part of the association secretes the acids, which react to dissolve the minerals, which are then used by the algae. Later, water seeps into the crevices etched by the acid, and assists in the breakdown through freezing (frost-wedging) and chemical weathering.
Explain how a plant can break a rock?
Plants break rocks through a process called bioweathering. Plant roots can release chemicals that enhance weathering, while the physical force exerted by the roots as they grow can also help break apart rocks. Over time, this can contribute to the fragmentation of rocks into smaller pieces.

The steps involved in breaking down mountain rock is called weathering. Weathering takes place naturally and is caused by wind, rain, ice, snow, and rivers. This breaks rocks into large pieces that continue to break down.
180 g of glucose and 342 g of sucrose have same number of molecules but different number of atoms. Explain?
They are different compounds with different molecules:- the chemical formula of glucose is C6H12O6- the chemical formula of sucrose is C12H22O11
