I would say D because mechanical weathering is the breaking up of rocks by physical forces
Because we have carbon in the ground in the air and every were else
<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.
Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>
