Earth's History and Rock Cycle Lesson

The rock cycle

This is a presentation about the rock cycle

Poll

Before we start I want to ask:

What is the rock cycle???

(This has no points so dont worry)

• The rock cycle shows how rocks are related and how the earth changes them over time.

• The rock cycle is a series of processes that create and transform the types of rocks in Earth’s crust.

• The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous.

The rock cycle

The rock cycle shows how rocks are related and how the earth changes them over time. This is a picture of the rock cycle. ------------------------>

First there are 3 types of rocks.

These are the 3 types:

Igneous

Sedimentary

and Metamorphic

First I'll make sure you understand each type of rock. First the igneous rock.

The Igneous rock is made by cooled down magma.

Open Ended

What is the rock cycle?

I will personally check them so don't worry!

Sedimentary rocks

Sedimentary rocks are formed by accumulation or deposition of the mineral.

Multiple Choice

What are sedimentary rocks?

• Rocks that are formed by the hotness and hardness of the ground

• Rocks that are formed by accumulation or deposition

• Rocks that are formed by cooled down magma

• They are caused by great heat and pressure

• All of the above

Metamorphic rocks

They are rocks that under go great heat and pressure

How does the rock cycle work???

Rocks turn from one type into another in an endless cycle. Inside Earth, heat, pressure, and melting change sedimentary and igneous rock into metamorphic rock. ... Intense heating results in hot liquid rock (magma) bursting through Earth's surface and turning into solid igneous rock. Then, the rocks get eroded and the process starts again

Multiple Choice

What is the rock cycle?

• The rock cycle shows how rocks are related and how the earth changes them over time.

• The rock cycle shows how soil eventually converts into a rock.

• The rock cycle shows how random objects get converted into a rock

• This shows that over time rocks can go from normal sand to obsidian.

• None

Multiple Choice

How are igneous rocks formed?

• The soil compacts and create sedimentary rocks

• Extreme heat and pressure

• Cooled down magma

• OBSIDIAN

Multiple Choice

How are sedimentary rocks formed?

• Extreme heat and pressure

• The soil compacts and create sedimentary rocks

• accumulation or deposition

Multiple Choice

How were metamorphic rocks formed?

• Extreme hotness and coldness

• Extreme heat and pressure

• The soil compacts and create sedimentary rocks

• All of the above
