Structure of the Earth and Energy Sources

Jake finds a rock with large, shiny crystals. He wonders how it was formed. What can you tell him?

• It formed from lava that cooled quickly.

• It formed from magma that cooled slowly underground.

• It formed from layers of sediments.

• It was created by heat and pressure.

Mia is hiking near a river and notices small pebbles and sand being carried by the water. What process is she observing?

• Weathering

• Erosion

• Deposition

• Melting

During a science experiment, Ben heats a rock and puts it under pressure. The rock changes but does not melt. What type of rock is Ben creating?

• Igneous

• Sedimentary

• Metamorphic

• Fossilized

Which of the following is NOT an agent of weathering?

• Water

• Wind

• Heat from magma

• Ice

Fossils are most commonly found in:

• Igneous rocks

• Metamorphic rocks

• Sedimentary rocks

• All rock types

What happens first in the formation of sedimentary rocks

• Sediments are pressed together.

• Rocks are broken down into small pieces.

• Magma cools and hardens.

• Heat and pressure change a rock’s structure.

Write T if the statement is true and F if it is false.

Rocks can transform from one type to another through natural processes.

Write T if the statement is true and F if it is false.

7. Igneous rocks are always formed on the Earth's surface.

Write T if the statement is true and F if it is false.

7. The rock cycle has a definite starting and ending point. 

Write T if the statement is true and F if it is false.

7. Erosion moves broken rock pieces from one place to another.
