True or False: Weathering is the carrying away of sediments caused by wind and water?

False, weathering is the process of breaking down rocks into smaller fragments known as sediments.

Give an example of PHYSICAL weathering.
-Running Water -Wind -Extreme Heat - Freezing of water between cracks of rocks - Plants growing between cracks in rocks - Animals digging holes in rocks

Which type of plates move together?
Convergent
400

Cracks in the ___________ allow magma to rise up from the mantle. 

Crust

400

True or false: If you dig deeper, you will find older fossils.

True. As sediments carried by wind and water are deposited and accumulate, they bury older layers—so the fossils in the deeper layers are older and those closer to the surface are younger.
