How can the air temperature lead to weathering of rocks
Answers:
1. Rocks expand and contract when they are heated and cooled, which can cause them to break.
2. the crust
3. sand
4. A crack must form in the rock.
trust me I did the test already

I agree, I got a 100% grade
answers are A, B, A, D
Dabuggy is good at this
Well, you see, rocks aren't like us humans who can just bundle up in a cozy sweater when it gets cold. When air temperature changes, the rocks can experience what we call thermal expansion and contraction. Just like when we try to squeeze into our favorite pair of jeans after a big meal, rocks can't handle the pressure. Over time, this expanding and contracting can lead to cracks and fractures in the rocks, making them more susceptible to weathering. So, basically, rocks need to invest in some thermal socks if they want to avoid all this trouble!
The air temperature can lead to weathering of rocks through a process called thermal expansion and contraction. Here's how it works:
1. Thermal Expansion: When rocks are exposed to high temperatures, such as intense sunlight or hot air, they absorb heat and expand. Different minerals within the rocks expand at different rates, causing stress and pressure within the rock structure.
2. Contrasting Temperatures: Rocks are often subjected to a wide range of temperatures, including both heat and cold. As the temperature changes throughout the day or over seasons, rocks expand and contract repeatedly.
3. Stress and Fracturing: The repeated expansion and contraction put stress on the rocks. Over time, this stress can cause cracks, fractures, and weaken the overall structure of the rock.
4. Increased Exposure: The cracks and fractures created by thermal stress provide pathways for air, water, and other weathering agents to penetrate deeper into the rock, accelerating the weathering process.
5. Frost Weathering: In colder regions, when water enters the cracks in rocks during warm periods and freezes during cold periods, it expands and exerts significant pressure on the surrounding rock. This process, called frost wedging or freeze-thaw weathering, can break apart rocks.
Overall, the constant cycle of heating and cooling, along with the expansion and contraction of rocks due to temperature changes, contributes to weathering by creating stress, cracks, and promoting the infiltration of weathering agents.
