Read this paragraph:

Imagine a big rock outside, and it gets really cold at night. Water seeps into cracks in the rock, and when the temperature drops below freezing, the water turns into ice. Ice takes up more space than water, so it pushes against the cracks, making them bigger and eventually splitting the rock apart.
