True or False: Weathering is the carrying away of sediments caused by wind and water?
False, weathering is the process of creating new soil by breaking down rocks into smaller fragments known as sediments.

Why do scientists believe that the mantle is liquid?

They believe that it is because the metal rocks are melted and mesh around the crust.

400

How are sedimentary rocks formed?

Weathering and erosion

What type of boundary causes earthquakes?

Transforming-sliding Boundary

Give and example of CHEMICAL weathering.
-Rocks destroyed by acid rain -lichens (produced by certain plants) produce acids and break down rocks.
