Starter
Draw a picture of the layers of the
Earth and label it. What are some
limitations to this model?
Practice:
Rock Color

Connection/Exit:
Your friends are having a debate
about how rocks should be
classified. One of them thinks it
should be by their composition,
while the other thinks should be
by the way they form. You pick a
side and explain why you agree
with that friend.

A.Composition-refers to the
minerals of rocks that are formed.
B. Texture-the shape, size, arrangement,

• Organic rock- come from
organisms- they are formed either
directly or indirectly from the

limestone
Rock Categories cont…
• Chemical rock-formed when a sea
or lake dries up, leaving large
amounts of minerals that were
dissolved in the water. Examples:
Rock salt and gypsum
Rock Categories cont…
• Metamorphic Rock-Formed
from already existing rocks are buried

effected by tremendous heat , great
pressure, and chemical reactions.
