Transcript of Chemical weathering
It is rock that has broken apart to pebbles and minerals.
Carbonic acid is especially effective at dissolving limestone. When the carbonic acid seeps through limestone underground, it can open up huge cracks or hollow out vast networks of caves.
Sometimes, chemical weathering dissolves large regions.
Chemical weathering changes the materials that make up rocks and soil. Sometimes, carbon dioxide from the air or soil combines with water.
This produces a weak acid, called carbonic acid, that can dissolve rocks.
