Rocks are found in lots of items you use every day, such as toothpaste, soap, and makeup!

2. Heat and Pressure

A sytofoam ball in the form of a head being compressed.

Over time, rocks can get buried deeper into the earth as dirt, leaves, and other natural elements cover them up.

As they go further down, the pressure of other layers above them presses on them. They're also exposed to heat as they get nearer to the Earth's center, causing them to soften.

1

When heat and pressure bear down on rocks over a very long period of time, they're compressed (flattened) and form metamorphic rocks.

2

Metamorphous rock

3

Metamorphic rocks have ribbon-like layers, and you can sometimes see sparkles or crystals in them.

4

Did you know?

Some examples of metamorphic rocks are marble and slate.

3. Weathering and Compacting

A meteorologist on a tropical island trying to speak into microphone during a hurricane. He is holding a banana blowup float.

During this phase, weather conditions such as wind and rain erode rocks and break them up into small particles. This phase occurs close to the surface of the earth, unlike the other phases, which take place deep in the earth.

1

Sedimentary rock

2

The small particles, along with sand, shells, plants, and other natural materials ("sediment"), are crushed and hardened together over time to form sedimentary rocks. When you look at a sedimentary rock, you can usually see a variety of particles in it.

Sedimentary rocks aren't as strong as other rocks, so they break down more quickly.

3

Did you know?

Sedimentary rocks are most likely to contain fossils!

Sal is walking on a trail near his home and stumbles on a rock.

A rock with google eyes on sand turns and looks in your direction.

Sal wonders, "Where do rocks come from? Why are they randomly in my path?"

A girl comes out of an underground bunker. She looks at numerous rocks all around.

The rocks around you have been forming for millions of years and represent the geography of your area. Learning about how they're formed will help you appreciatethe amazing cycle of rocks!

Did you know?

The oldest rock formation in the world is in Quebec, Canada and is estimated to be 3-4 billion years old.

The Rock Cycle Rocks!

The rock cycle is the process by which rocks are formed and re-formed.

It's an ongoing process that has no beginning and no end.

The earth is like a rock recycling machine! During the process, 3 main typesof rocks are created. Rocks change from one type to the other over time in 3 phases.

1. Melting and Cooling

Molten rock inside a volcano

The interior of the Earth is hot and molten. This hot substance is known as magmawhen it's below Earth's surface and lava when it erupts.

When rocks are exposed to this intense, fiery heat, they melt.

When magma cools on Earth's surface either due to a volcanic eruption or by oozing through a crack, igneous rocks are formed.

Shiny black igneous rock

Igneous rocks are often shiny, but some of them are dull and have small holes.

Quiz

True or false? An igenous rock will always remain an igneous rock.
