Rocks!

Question 1

What are the three types of rock

Answer 1

Igneous
Sedimentary
Metamorphic

Question 2

What are the igneous rocks?

Answer 2

Granite and basalt

Question 3

What is geology

Answer 3

The study of rocks

Question 4

How do igneous rocks form?

Answer 4

They form when lava and magma cool down and form granite and basalt

Question 5

Where does granite form?

Answer 5

Granite forms slowly underground

Question 6

Where does basalt form?

Answer 6

It cools fast on the surface

Question 7

Make an ingenous rock diagram

Answer 7

Good job man

Question 8

Describe the formation of granite

Answer 8

When magma cools deep inside the earth’s crust, it cools very slowly over thousands of years. This allows the different minerals in the magma, such as silica, to grow into crystals.
The presence of these crystals in the rocks is a sign that the rock is granite.

Question 9

Describe the formation of basalt

Answer 9

If lava erupts out of a volcano, it cools quickly on the earth’s surface as it comes in contact with air, frost, snow and water. This fast cooling does not allow the crystals, e.g. silica, to grow very big. In fact, they are microscopic.

Question 10

What are the sedimentary rocks?

Answer 10

Limestone
Sandstone
Coal

Question 11

What is the most common form of rock in Ireland

Answer 11

Sedimentary rock (limestone)

Question 12

Describe the formation of sedimentary rock

Answer 12

-rock particles build up on the sea floor or lake bed
-the great weight of sediments squashes the air and water out from between the grains of rock (compaction
-calcite or silica minerals in the sediments stuck the grains together to make a solid rock

Question 19

What are the metamorphic rocks?

Answer 19

Quartzite
Marble
Slate

Question 20

How do metamorphic rocks form?

Answer 20

When the great heat of magma and lava as well as pressure from plate movement changes rocks

Question 21

What temperature can magma and lava reach?

Answer 21

1200 degrees

Question 22
