One example of an agent of physical weathering in a rock is ice. When water seeps into cracks in a rock and then freezes, it expands, causing the rock to break apart. Over time, repeated freezing and thawing can lead to the release of rock fragments through a process known as frost wedging.
What else can I help you with?
Which is an agent of physical weathering?
Frost is an agent of physical weathering. When water freezes in cracks in rocks, it expands and exerts pressure on the surrounding rock, causing it to break apart.
What is the most active agent of physical weathering?
The most active agent of physical weathering is water. Water can seep into cracks in rocks, freeze, expand, and cause the rock to break apart. This process is known as frost wedging and is a common form of physical weathering.
What are the agents of biological weathering?
The agents of "weathering" is both the agents of the physical and the chemical weathering combined. Agents of physical weathering can be: wind, water, sun, ice, gravity, rain, etc. Agents of chemical weathering may be: acid from roots, acid rain, oxidation/reduction (rusting), carbon dioxide, etc. They are the same because both physical and chemical weathering lead to erosion of rocks. In other words, both help rocks break down into smaller pieces. They are also the same because both physical and chemical weathering can occur with the same agent. For example, TREES. The roots of trees release acid to break down rocks (chemical weathering) while the roots of trees also grow into the cracks of rocks and help break them apart (physical weathering). Note that weathering is just the beginning process of erosion. Erosion is when stuff actually breaks down into smaller pieces.
What True or false the most important agent of chemical weathering is abrasion?
False. The most important agent of chemical weathering is water, through processes such as hydration, dissolution, and oxidation. Abrasion is a physical weathering process caused by friction and impacts between rock surfaces.
What type of weathering causes acid rain?
Chemical weathering causes acid rain. When sulfur dioxide and nitrogen oxides are released into the atmosphere from human activities, they combine with water vapor to form sulfuric acid and nitric acid, which then fall to the earth's surface as acid rain.
Can ice be an agent of chemical weathering?
No ice is an agent of physical weathering

Is the most important agent of chemical weathering abrasion?
No, the most important agent of chemical weathering is typically water. Water helps break down rocks through processes like hydration, hydrolysis, and oxidation. Abrasion, which is the physical wearing down of rocks by friction and impact, is an example of mechanical weathering rather than chemical weathering.
What is the acid precipitation is an agent of weathering?
acid precipitation is an agent of -------weathering

Is salt an agent of physical weathering?
It can be if it crystallises inside a porous rock the salt crystals can crack the rock.
What True or false the most important agent of chemical weathering is abrasion?
False. The most important agent of chemical weathering is water, through processes such as hydration, dissolution, and oxidation. Abrasion is a physical weathering process caused by friction and impacts between rock surfaces.

Chemical weathering causes acid rain. When sulfur dioxide and nitrogen oxides are released into the atmosphere from human activities, they combine with water vapor to form sulfuric acid and nitric acid, which then fall to the earth's surface as acid rain.
Acid precipitation is an agent of what kind of weathering?
Chemical weathering.
Is deposition an agent of weathering?
no
What agent of weathering the breaking of rocks?
The agent of weathering responsible for breaking rocks is mainly mechanical weathering. This process involves physical forces like wind, water, and ice that break down rocks into smaller pieces without changing their chemical composition. Examples of mechanical weathering include frost wedging, abrasion, and root pry.
