Earth & Rocks (2025)

Match the following!

• Earth's top layer of solid rock that includes both dry land and ocean floor.

• Crust

• Earth's solid 2nd layer of hot rock that is nearly 2,000 kilometers thick.

• Core

• Earth's metal inner layer that is made mostly of iron and nickel.

• Mantle

Imagine you are taking a submarine drilling machine to the center of the Earth. Order the events below so that your journey makes sense!

• Dive beneath the ocean waves and drill through the oceanic crust made of basalt.

• Collide with the molten metal of the outer core as your drill machine begins to shiver and shake.

• Hit the solid part of the mantle just above the Earth's core where temperature approach 2,000 degrees F.

• Break into the most hottest and most dense layer of iron and nickel that exists inside our planet.

• Crack into the rigid lithosphere and then into the softer asthenosphere.

Why is the hottest layer of the Earth (inner core) a solid instead of a liquid or gas?

• Atoms contained in the core are under so much pressure they cannot spread out.

• Metals contained in the core are so hot they cannot spread out.

• Particles contained in the core are under so much water they stay cool.

• Pieces of ice floating in the outer core help keep the inner core cool.

Reorder the following steps in Earth's creation from earliest to most recent!

• Dust Molecules Combine in Space

• Earth Melts Into Giant Lava Ball

• Larger Rocks Collide Forming Earth

• Big Bang (Universe Begins)

• Earth's Crust Begins to Cool
