The Sun contributes to physical weathering through a process called thermal expansion and contraction. When rocks are exposed to the Sun, they heat up and expand during the day, and then cool down and contract at night. This repeated cycle can cause rocks to crack and break apart over time, leading to physical weathering.

What does not contribute to physical weathering?
Chemical reactions do not contribute to physical weathering. Physical weathering refers to the breakdown of rocks into smaller pieces without any change in their chemical composition.
Do humans contribute weathering?
Yes, humans contribute to weathering through activities such as mining, construction, and deforestation, which can accelerate the process of physical and chemical weathering. Additionally, pollution from human activities can lead to acid rain, which can further enhance chemical weathering.
Is moss physical or chemical weathering?
Moss does not directly cause physical or chemical weathering itself. However, moss can indirectly contribute to chemical weathering by producing organic acids that can break down rocks over time. Additionally, moss can also contribute to physical weathering by helping to break apart rocks as their roots grow into cracks and crevices.
What are the agents (causes)of physical weathering?
Physical weathering is primarily caused by factors such as temperature changes, ice formation, wind erosion, and the action of plant roots. Additionally, abrasion from water, glaciers, and rockslides can also contribute to physical weathering processes.
What living organisms contribute to physical weathering?
Plants with their roots can contribute to physical weathering by breaking through rocks as they grow. Burrowing animals such as earthworms and rodents can also contribute by tunneling through the ground and breaking up rock particles. Ice wedging, where water freezes and expands in cracks in rocks, is another process of physical weathering caused by living organisms.

How are physical weathering and chemical weathering alike and different?
Physical weathering and chemical weathering both involve the breakdown of rocks, but through different processes. Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their composition, while chemical weathering involves the alteration of rock composition through chemical reactions with substances like water, oxygen, and acids. Both processes contribute to the overall erosion of rocks and landforms over time.
Why sun is agent of weathering?
The sun is not considered an agent of weathering. Weathering refers to the process of breaking down rocks and minerals on the Earth's surface, which is primarily caused by factors like water, wind, and temperature changes. The sun's energy can contribute to weathering indirectly by causing temperature changes that lead to expansion and contraction of rocks, but it is not a direct agent of weathering.
Is abrasion physical weathering or chemical weathering?
it is physical weathering
Are the three types of weathering?
The three types of weathering are mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering involves physical processes like freezing and thawing that break down rocks. Chemical weathering involves chemical processes like oxidation and dissolution that alter the composition of rocks. Biological weathering involves living organisms, such as plants or burrowing animals, that contribute to the breakdown of rocks.
Is weathering same as physical weathering?
No weathering is not the same as physical weathering.Kayla
How are physical weathering and chemical weathering alike?
how are physical weathering and chenical weathering alike and different
Living things play no role in physical or chemical weathering?
Actually, living organisms can play a significant role in both physical and chemical weathering processes. For example, tree roots can break apart rocks through physical weathering, while certain microorganisms can produce acids that contribute to chemical weathering. In general, the presence of living organisms can speed up the weathering of rocks and minerals.
