What is the agent in mechanical weathering where the sun or forest fire causes rock to crack?
The agent in mechanical weathering where the sun or forest fire causes rocks to crack is thermal expansion and contraction. This process occurs when rocks are exposed to heat from the sun or a fire, causing them to expand and contract at different rates, leading to cracks and eventual breakdown.
Is thunder an agent of weathering?
No, thunder is not an agent of weathering. Weathering refers to the breakdown of rocks and minerals on the Earth's surface, typically caused by processes like water, wind, or ice. Thunder is the sound produced by lightning during a thunderstorm.
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 kind of weathering is acid precipitation an agent of?
Acid precipitation is an agent of chemical weathering. It occurs when rain, snow, or fog has a high acidic content due to pollutants such as sulfur dioxide and nitrogen oxides, which can cause rocks to break down and deteriorate.
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.
Can ice be an agent of chemical weathering?
No ice is an agent of physical weathering
What is the acid precipitation is an agent of weathering?
acid precipitation is an agent of -------weathering
What is the agent in mechanical weathering where the sun or forest fire causes rock to crack?
The agent in mechanical weathering where the sun or forest fire causes rocks to crack is thermal expansion and contraction. This process occurs when rocks are exposed to heat from the sun or a fire, causing them to expand and contract at different rates, leading to cracks and eventual breakdown.
Acid precipitation is an agent of what kind of weathering?
Chemical weathering.
Is deposition an agent of weathering?
no
What are the agent of rock?
what are the agents of weathering
What are four factors that affect how fast weathering happens?
the nature of the material weathered (shape, size, composition) the nature of the weathering agent the frequency of the weathering agent the properties of the surrounding environment
How unloading acts as a weathering agent?
Unloading acts as a weathering agent by breaking bedrock into smaller pieces. This increases the surface area along which chemical reactions can occur, which eventually leads to weathering.
How can gravity act as an agent of weathering?
If you drop a rock and it breaks into pieces, then that is an act of mechanical weathering.
The most important agent of chemical weathering?
Water
How animals become the agent of weathering?
by scratching the rocks
How can you avoid being an agent of weathering?
Do not visit places you do not want to contribute to the weathering of and do not burn any fuels.
