What are the three basic types of rocks?
Sedimentary, Igneous, and Metamorphic
100
When looking at a rock, what is an easy way to identify it as sedimentary?

-It has many tiny bits of sediment in it.

or 

-It has layers.

100
How could an igneous rock change to a sedimentary rock?
It could be broken into tiny pieces and become sediment, then become part of a new sedimentary rock.

What do butterflies have in common with metaMORPHic rocks?
They both change!
100

VOLCANOES

EARTHQUAKES

What creates vesicles in pumice rocks? (igneous)
gas bubbles
200
What are sedimentary rocks made of?
Sediments: clay, sand, shells, rock bits, organic material, etc.
200
How could an igneous rock change to a metamorphic rock?
Extreme heat and pressure are applied.
200
What does MORPH mean?
to change
200
What is deposition?
The DROPPING of particles in another location.
300
What does "ignis" mean in Greek?
fire
300
How could a sedimentary rock change into an igneous rock?
It is heated and melted then cools.
300
What kind of structures do many igneous rocks have inside?
crystals
300
Why do we NOT commonly find many fossils in metamorphic rocks?
The extreme heat and pressure would destroy the organic material creating the fossil.
300
What is EROSION?
The MOVEMENT of sediment or soil from one place to another
400
Do all scientists agree how long it takes rocks to form? Explain.

No. Some scientists believe it takes millions of years and other scientists believe it takes much less time. Varied answers.

What is WEATHERING?
The BREAKING DOWN of substances like rocks

When lava cools very, very slowly, what do the igneous rocks often look like? 

glass, like obsidian

500
Where are many sedimentary rocks formed?
lakes, oceans, and river beds
500
How are igneous rocks formed?
From magma or lava that has cooled
500
How are metamorphic rocks formed?
Extreme heat and pressure are applied to igneous, sedimentary, or even other metamorphic rocks.

What are TWO ways in which our earth changes SLOWLY?
weathering and erosion
