CT River Valley was formed this way.
What is a divergent boundary?
500
Plants, algae, lichens, fungi, and bacteria can dissolve rocks for nutrients.
What is chemical biological weathering?
500
Triangle-shaped area at the mouth of a river and where deposition occurs.
What is a delta?
500

This law of stratigraphy states that rock layers are generally deposited flat.

500

This takes place when when Earth is between the Moon and the Sun and all three are lined up in the same plane.
