The Earth

100

How many layers are in the geosphere?

4 Layers

200

This is the center part of the Earth. It is also the hottest part with temperatures of up to 5,500 degrees celcius.

The Inner Core

300

This is the liquid layer around the inner core. 

The Outer Core

400

This is the thickest layer of the geosphere. It is made up of magma, which is semi-liquid rock.

The Mantle

500

This is the top layer of the geosphere... It is thinner than the other layers and is solid. 

The Crust

Rocks

100

What is the lithosphere made of?

Rocks

200

Rocks are made up of...?

Minerals

300

This is the solid outer part of the geosphere... Including the crust and the top part of the mantle. 

The Lithosphere

400

This type of rock is only made up of one mineral... Calcite

Marble

500

This type of rock is made up of three different minerals; Quartz, Feldspar, and Mica

Granite

Classifying Rocks

100

How many groups do we classify rocks into?

3 Groups

200

These types of rocks are formed by sediments that are carried by rivers and settle at the bottom of lakes, seas or oceans. 

Sedimentary Rocks

300

These types of rocks are formed by magma in the Earths mantle. When magma comes to the surface through volcanic eruptions, it cools and forms this type of rock. 

Igneous Rock

400

These type of rocks are originally sedimentary or igneous rocks.  These are then transformed over time by intense heat and pressure below the Earth's surface.

Metamorphic Rocks

500

These are small solid particles that are carried by a river... 

Sediments

Using Rocks

100

We use this type of rock to write things on the board. 

Chalk

200

We use this for the roofs of houses. 

Slate

300

We use this type of rock for floors and work surfaces... It is smooth and sometimes can be a name for a small ball. 

Marble

400

We use this type of rock to build houses.

Granite

500

In what type of rocks are fossils normally found?

Sedimentary Rocks

Classifying Minerals

100

This is one way to classify a mineral according to how it looks and the shade of _____ that it has. 

Colour

200

Another way of saying ¨shininess.¨ We can classify this way according to how shiny or dull they are. 

Lustre

300

Minerals can occur in crystal form. Some crystals break into different parts with flat surface and is called ____. Others leave a more uneven surface which is called ______. 

Cleavage and Fracture

400

The _____ is how difficult it is to scratch another surface. We also use the Mohs Scale to measure it. 

Hardness

500

What is the hardest natural mineral on earth and what is its hardness on the Mohs Scale?

Diamonds - 10
