300
A type of vegeatation that includes broad-leaved evergreen shurbs and that is located in areas with hot, dry summers and mild, wet winters.
What is chaparral?
300
Magma that flows onto Earth's surface; the rock that forms when lava cools and solidifies.

What is continental drift?
400
An area where fresh water mixes with salt water from the ocean.
