Physical and chemical weathering are different because they break the rocks down into very different size pieces over time.
Physical weathering requires a physical force to break rocks down, but chemical weathering causes compounds in the rock to react chemically.
Physical weathering involves the physical movement of broken down rock, but chemical weathering causes the rock to soften and stay in the same plaace.
Physical weathering is very slow and takes a lot longer to break down rock than chemical weathering does.

Question 6
This is a picture of marble chips - small pieces of marble rock that we use in the Science lab. Would it be easier and faster to chemically weather these small pieces than it would be to chemically weather a marble boulder? Yes or no, and why or why not?
No. They would chemically weather at the same speed because the boulder and the chips are made of the same minerals.
Yes. The marble chips are already smaller than a boulder, so they are probably softer too.
No. The boulder would weather faster because it's surface is huge and it is outside, so chemicals and acid rain would break it down faster.
Yes. The marble chips provide more surface area for the chemical weathering to act upon.

Trial 4.
Question 15
How do physical and chemical weathering work together to weather rocks?
Physical weathering breaks rocks into smaller pieces so more surface is available for chemical weathering to act on.
Physical weathering involves force and it always happens first. Chemical weathering requires very special conditions afterwards.
Chemical weathering causes chemical changes in the rock's surface that attracts animals to help it break down physically.
Chemical weathering can change and soften a rock's surface so that it is easier for physical weathering to break it apart.
Question 16
Weathering, sedimentation, erosion, igneous, and metamorphic are all terms related to Earth's never-ending ______________________________.
water cycle
carbon cycle
rock cycle
subcycle
Question 17
Although we tend to think of weathering and erosion as negative processes, they are actually necessary to life on Earth as we know it. Why?

Because without weathering and erosion we would not have any sand on the beaches.
Because they combine to keep the convection currents in the mantle moving.

Question 3
Why do darker color fabrics get warmer than lighter color fabrics when they are in the sun? Carefully read the following explanation, and decide whether it is true or false.
