• When the rock dries.

How do chemical rocks form?

• When it get compacted into small peices.

• When it erodes.

• When minerals are dissolved in a solution and crystallize.

How do clastic rocks form?

• When rock fragments are squeezed together.

• When minerals are dissolved in a solution and crystalize.

• When it erodes and breaks down into chunks.

Erosion occurs when running water or wind loosen and carry away fragments of rock.
