100

The breaking apart of rocks (not what the weatherman does).

What is weathering?

100

Large cracks in the Earth's surface.

What are faults?

100

A mixture of rocks, sediment and organic matter (it's in the title).

What is soil?

100

We live on this continent.

What is North America?

100

The layer just below the Earth's crust (or what's above a fireplace).

What is a mantle?

200

This "hot stuff" is found in the mantle layer of Earth, and becomes lava when it reaches the surface.

What is magma?

200

There's a whole lot of shakin' going on when a fault moves suddenly.

What is an earthquake?

200

These particles are the largest pieces of rock, water moves easily through it.

What is sand?

200

There are 7 of these large landmasses on Earth.

What are continents?

200

This "hot head" releases magma, cinders, ash and gases.

What is a volcano?

300

This type of rock is formed when sediment builds up and presses on lower layers of sediment.

What is sedimentary rock?

300

The exact place in the Earth where an earthquake occurs.

What is focus?

300

The natural process of moving rocks and sediment.

What is erosion?

300

The Earth's surface is divided into these large areas (that don't fit in the dishwasher).

What are tectonic plates?

300

These are formed when animal tracks and/or imprints of plants are made in sediment.

What are fossils?

400

This type of rock is formed when magma or lava cools and hardens?

What is igneous rock?

400

The place on the Earth's surface above the focus where an earthquake causes the most damage.

What is the epicenter?

400

The soil layer that has less humus and fewer living things.

What is the subsoil layer?

400

The outer most layer of Earth (or what some kids want cut off of their sandwiches).

What is the crust?

400

The layer in the center of the Earth (and it's not Hell).

What is the inner core?

500

This type of rock is formed by heat and pressure (also, a cool name for a superhero).

What is metamorphic?

500

"Surf's Up, Dude!"  This large mass of moving water is caused by a strong earthquake under the ocean.

What is a tsunami?

500

The best for growing plants, this soil layer is a mixture of humus and sediment, plus worms, insects and other animals.

What is the topsoil layer?

500

The three ways tectonic plates move (and they rhyme, if said correctly).

What is Slide, Collide & Divide (or Separate)?

500

The third layer of the Earth.

What is the outer core?
