Rock Cycle and Plate Tectonics

Question 1

What is the name of the supercontinent?

Answer 1

Pangaea

Question 2

How long ago did the Earth’s supercontinent split?

Answer 2

200 mya

Question 3

What causes the plates to move?

Answer 3

Convection currents beneath the plates

Question 4

Who is Alfred Wegener?

Answer 4

German researcher who started the term “continental drift”

Question 5

Who is J Tuzo Wilson? And what did he do?

Answer 5

J Tuzo Wilson expanded on Wegener’s ideas and proved continents move on parge plates or crust sections

Question 6

What are the 3 types of Plate Tectonic movements?

Answer 6

Transformation Plate Boundary, Divergent Plate Boundaries and Convergent Plate Boundary

Question 7

What is the Divergent Plate Boundaries and what is an example of it?

Answer 7

Movement of plates in opposite directions; Mid Atlantic Ridge

Question 8

What are the 2 types of Convergent Plate Boundary, what are they and an example for each?

Answer 8

Can be classified as mountain building ( ex. Himalayas )or Subduction Zone ( Western Canada ). Subduction zone is when 1 plate goes under the other and mountain building is when both plates get pushed up.

Question 9

What is the Transformation Plate Boundary and what is an example of it?

Answer 9

Movement or Slide of plates back and forth along each other. San Andreas Fault in California

Question 10

What is the rock cycle?

Answer 10

The rock cycle is used to explain how the three rock types change into each other.

Question 11

What are the 3 types of rocks?

Answer 11

Igneous, Sedimentary, and Metamorphic

Question 12

What are Igneous Rocks?

Answer 12

Any rock formed through the cooling of lava or magma

Question 13

What are some examples of Igneous Rocks?

Answer 13

• Granite
• Basalt
• Obsidian
• Diabase

Question 14

What is the difference between Magma and Lava?

Answer 14

Magma is any sort of liquid Earth that is inside the earth, as soon as it is on the surface of the Earth, it’s called lava.

Question 15

What happens when Igneous Rocks go through weathering and erosion.

Answer 15

It turns into Sediments

Question 16

What happens when Igneous Rocks go through heat and pressure?

Answer 16

It turns into a metamorphic rock

Question 17

What happens when Igneous Rocks go through melting?

Answer 17

It turns into Magma

Question 18

What are Metamorphic Rocks?

Answer 18

Metamorphic Rocks are ones that come from heat and pressure

Question 19

What are some examples of Metamorphic Rocks?

Answer 19

• Gneiss
• Quartzite
• Marble

Question 20

What happens when Metamorphic rocks go through melting?

Answer 20

It turns into Magma

Question 21

What happens when Metamorphic rocks go through weathering and erosion?

Answer 21

It turns into Sediments

Question 22

What are Sedimentary Rocks?

Answer 22

Sediments are deposited together and are “cemented” to form a sedimentary rock.

Question 23

What are Sediments?

Answer 23

Sediments can be anything that are broken down, transported and deposited

Question 24

What are some examples of Sedimentary Rocks

Answer 24

• Shale
• Coal
• Limestones
• Sandstone

Question 25

What happens when Sedimentary Rocks go through weathering and erosion?

Answer 25

It turns into Sediments

Question 26

What happens when Sedimentary Rocks go through heat and pressure?

Answer 26

It turns into Metamorphic Rocks

Question 26

What happens when Magma goes through cooling?

Answer 26

It turns into Igneous Rocks

Question 26

What happens when sediments to through compaction and cementation

Answer 26

It becomes Sedimentary Rocks

Question 26

What causes the rock cycle?

Answer 26

Plate tectonic movement is responsible for cycling rocks through the rock cycle

Question 27

How many years ago was pangea formed?

Answer 27

Pangea was formed 300 mya
