General Rock Cycle
How many types of rocks are there? Please name each type of rock.
3 types of rocks. Igneous, sedimentary, metamorphic.
How do Igneous Rocks form?
Igneous Rocks form from magma or lava.
What are sedimentary rocks formed by?
Particles of broken rock, dead plants and animals, are pressed together to make sedimentary rock.
True or False:
Metamorphic rock is rock that has changed from another type of rock due to pressure or heat
True!
How old is Mr. Art?

What is the term for the natural process of how rocks change over time?
The Rock Cycle
What is one way igneous rock could come to the earth's surface
A volcanic eruption!
If I went looking for sedimentary rock, where would be the best place to search for it?
Riverbeds, lakebeds, the ocean floor and some of the best places to find sedimentary rocks.
True or False:
Marble is a type of metamorphic rock
True!
We are in J. Blume classroom. What does the 'J' in J. Blume stand for?

Judy Blume.
True or false:
Minerals in rocks have orderly crystal structures
True! All crystal structures are orderly!
What are the two types of igneous rock?
For a bonus point! Pick one of the questions below:
How are these two types of rock different?
or
What word does Igneous rock come from in Latin?
Intrusive and Extrusive
Intrusive is formed from slowly cooling magma in the earth. While extrusive rock is formed by cooling slowly on the surface of the earth.
///
Ignis - Latin - meaning 'fire'
True or false:
Sedimentary rocks like sandstone and limestone form in layers.
True! The old sediments form under the newer sediments (over and over again)

True or False:
Extrusive igneous rock has large mineral crystal structures
False! Extrusive igneous rocks have small crystals because they are often molten and cool quickly.
True or false:
Sedimentary rock is a great way to study ancient winds and water levels.
True!
Over time wind patterns and water levels leave crossbeds, ripples and cracks on sedimentary rocks.
What is a metamorphic rock with no foliage called?
Nonfoliated!
This may happen because the rock is made of only one mineral! This means the different minerals may not separate and line up. An example of this type of rock is marble.
