sediments

2

magma

Multiple Choice

Question image

When lava cools quickly on the surface, there is not enough time for ___ to form, so igneous rocks like, obsidian, are created.

1

ash

2

minerals

3

crystals

What do we know about Extrusive Igneous Rocks?

  • They are made from cooled magma.

  • They are created on the Earth's surface.

  • They cool too quickly for crystals to form inside them.

  • The can have holes to show that gas has escaped.

11

Intrusive Rocks

Igneous rocks created beneath the Earth's surface

Slide image

12

Intrusive Rocks

  • Form underground

  • Slow cooling

  • crystals form

  • crystals form mixed patterns inside the rock

Igneous rocks that form under the Earth's surface are called

1

crystals

2

extrusive

3

intrusive

14

Multiple Select

Question image

Does an intrusive igneous rock have crystals?

1

no

2

yes

15

Multiple Select

Question image

Why do intrusive igneous rocks have mixed crystal patterns?

1

the magma cools too slowly

2

the magma cools too quickly

16

How can you tell an extrusive igneous rock from an intrusive igneous rock?

Texture and composition

Slide image

17

Multiple Select

Since the magma cools too quickly on the surface crystals do not form. So if you don't see crystals it is an extrusive rock.

1

True

2

False

18

Multiple Select

Since magma cools down slowly underneath the surface crystals are able to form, so if you can see the crystals in weird patterns, it is an intrusive rock.

1

True

2

False
