How do cracks affect the rate of weathering?

The answer is; cracks increases weathering

When water enters the cracks and is heated up, it expands and pushes against the crack from the inside. Also, it is important to note that water also expands when it cools below 4 degrees centigrade. When it does, it causes the cracks to get bigger and cracks the rocks more.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
