Rocks
Sets of Three
100
The outermost layer of the Earth.
What is the crust?
100

The primary source of natural light on Earth.

What is the Sun?

100

This is the boundary between two air masses with different temperatures and densities. 

What is a weather front?

100

The process by which rocks are form, transformed, and reformed.

What is the rock cycle?

100

Solids, liquids, and gasses

What is the stages of matter?

200
The center of the Earth.
What is the core?
200

When light bounces off a smooth, shiny surface.

What is reflection?

200

The movement of a warm front is typically this compared to a cold front.

What is slower?

200

A naturally formed solid matter that has crystalline structure on the interior.

What is a geode?

200

Reflect, Transmit, Absorb

What is the Properties of Light?

300
The layer of the Earth between the crust and the core.
What is the mantle?
300

Anything that produces or emits light.

What are light sources?

300

These types of clouds are often associated with long periods of light rain or snow.

What are stratus clouds?

300
Rocks that form when hot, liquid rock (magma) cools.
What are igneous rocks?
300

Humidity, Wind, Temperature

What are the Properties of Weather?

400

Large pieces of the lithosphere that move around on the Earth's surface.

What are tectonic plates?

400

The bending of light as it passes from one material to another, like from air to water.

What is refraction?

400

This type of front occurs when two air masses meet and neither one is strong enough to move the other, resulting in a period of stable weather.

What is a stationary front?

400
Rocks whose structure, composition, and texture have changed from those of the original rock.
What are metamorphic rocks?
400

Cumulus, Cirrus, Stratus

What is Main Types of Clouds?

500

The lines that earthquakes occur along.

What are fault lines?

500

The range of colors that we can see.

What is the visible spectrum?

500

This type of weather is common ahead of a cold front.

What are violent storms?

500

The rock that forms the ocean floor.

What is basalt?

500

Heat and pressure, Melting, Erosion
