Sedimentary rocks
These rocks are formed from particles of sand, shells, and other fragments of material.

Convergent
What is the type of plate movement when two plates moved toward each other?
100
crust
What is the top layer of earth called?

weathering
What is it when a rock loses small particles but the particles stay next to the rock?
100
humans
What is another factor in the destruction of the earth's surface?
200
Metamorphic rocks
These rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing).
200
Sliding or Transform
Which type of plate movement is when two plates rub against each other and csues friction?
200
inner & outer

200
erosion
What is it called when rock sediment is washed away?
200
yes
Do the activities of humans produce compounds that cause acid rain?

Igneous rocks
These rocks are formed when magma (molten rock deep within the earth) cools and hardens.
