Unit 3 Lesson 2: The Rock Cycle

The Rock Cycle

What is the rock cycle? ​

By the end of this lesson, you should be able to describe the series of processes and classes of rocks that make up the rock cycle.

Multiple Choice

Most of Earth is made of __________.

• rocks

• water

• air

• photons

Multiple Choice

Rock is __________ changing.

• never

• always

• sometimes

• rarely

Multiple Choice

The three main classes of rocks are igneous, metamorphic, and ___________.

• spaceship

• clastic

• minerals

• sedimentary

Open Ended

Explain weathering, erosion, and deposition...

Scientists define rock as a naturally occurring solid mixture of one or more minerals that may also include organic matter.

Rocks are always changing and we will look at how they change through time.
