Igneous rocks can be found around or in these.
What is a volcano?
100
This is what sedimentary rocks start off as.
What is sediment?

These are rocks that can become metamorphic rocks.
What are sedimentary, igneous, and most metamorphic rocks?

Theresa is 7 years old and Larry is 10 years old. 

What is Absolute Dating?

200
Liquid rocks or minerals may be called _______
What is molten rock?
200
The movement of sediment.
What is erosion?
200
These two things are required for a metamorphic rock to form.
What are heat and pressure?
200
A rock that was sediment, then went under pressure, then was melted down and crystalized or cooled inside a volcano is this type of rock.
What is a igneous rock?
200

This Law states that, in horizontal sedimentary rock layers, the oldest layer is at the bottom, and each higher layer is younger than the layers below it. Faults, intrusions/extrusions, and unconformities complicate this process.

What is Law of Superposition? 

300
Rock that is found inside a volcano is most likely make from this type of molten rock.
What is magma?
300

The layers of rock that are laid down one on top of another. 

What is strata?

300
Sandstone (sedimentary) must go through his to become Quartzite.
What is heat and pressure?
300
These types of rocks can become sediment by weathering.
What is any type of rock?

Why is it impossible to find the absolute age of sedimentary rocks?

Fossils are only found in sedimentary rock, and we can't find the absolute age of it. However, paleontologists can find the absolute age of nearby igneous intrusions/extrusions and then use the Law of Superposition to determine the age of the sedimentary rock layers.

What is an intrusion? 

A mass of igneous rock that forms when magma pushes into a body of rock and cools and hardens

What is a fossil?

A fossil is the evidence or remains of once living things.

400
This is why metamorphic rock is great for building.
What is durable and strong?

How is silt formed?

A. Sand and Clay

B. Clay and Mud

C. Sand and sediment 

What is A. Sand and Clay

Why are fossils only found in sedimentary rock?

Fossils would be destroyed by heat and/or pressure during the formation of igneous and metamorphic rocks. Sedimentary rocks are formed when sediments build, layer upon layer, and gradually cement and harden. Fossils can easily become trapped and preserved in the layers.

What is the ring of fire?

The Ring of Fire is made up of more than 450 volcanoes and is prone to earthquakes. It's a horseshoe-shaped arc of mountains, active volcanoes, and oceanic trenches that runs for nearly 25,000 miles.

500

This type of rock is formed from dead trees and plants (also known as fossils) ? (hint: non-renewable resource). 

What is coal?

What kinds of information do Paleontologists get from fossils?

Paleontologists use fossils to help them determine what past life forms were like, how they changed over time, how the Earth's surface has changed and what the past environments were like.

500
This is how rocks on the surface get pushed into the Earth's core.
What is pressure?

Why is carbon-14 more useful in dating materials from plants an animals that are lived only as long as 50,000 years ago (relatively young in geologic terms)?

It has a half-life of only 5,730 years, so it can't be used to date ancient rocks and fossils; the amount of Carbon-14 left to compare would be too small to measure accurately for materials more than 50,000 years old.
