MY NOTES

Question 1

Seafloor spreading

Answer 1

Ocean floor moving apart (MidATLANTIC RIDGE)

Question 2

Converging boundaries

Answer 2

Plates are moving together and colliding

Question 3

When two continent plates converge what happens

Answer 3

Folded mountains

Question 4

True or false

Subduction always involves a continental plate

Answer 4

FALSE subduction always involves an oceanic plate

Question 5

True or false

The oceanic plate moves over the continental plate while converging

Answer 5

False the oceanic plate moves under as it is lighter

Question 6

Transform boundaries

Answer 6

Plates slide past each other

Question 7

True or false

Transform boundaries cause volcanoes

Answer 7

False transform boundaries cause earthquakes

Question 8

Hotspot

Answer 8

Super heated fixed plume of mantle in the mantle is forced to the surface as the plate moves over the plume, volcanoes become dormant and new ones form creating a volcanic chain

Question 9

UNIT TEST

Cratons

Answer 9

Oldest rock on earth

Question 10

UNIT TEST
True or false
Appalachian mountains formed as a result of pangea tru

Answer 10

TRUE Appalachian mountains formed as a result of pangea

Question 11

Answer 11

FALSE its a famous transform boundary

Question 12

UNIT TEST

Earths core consists of gold and coper

Answer 12

FALSE earths core consists of iron and nickel

Question 13

UNIT TEST
True or false
The mantle is the greatest volume of the EARTHS interior

Answer 13

True the mantle in the greatest volume of the earths interior

Question 14

Western cordillera is Canada’s youngest geologic mountain chain

Answer 14

Yep

Question 15

What is isostatic rebound

Answer 15

The uplift of the crust due to glacial retreat

Question 16

What was Alfred wegener’s theory

Answer 16

Continental drift

Question 17

Pangea occured

Answer 17

200 million years ago

Question 18

You can find what in the canadian shield

Answer 18

Ancient cratons

Question 19

What is till

Answer 19

Deposits from glaciers

Question 20

True or false

The mid atl ridge was the first discovery of a divergent plate

Answer 20

False first discovery of seafloor spreading

Question 21

What do hawaii and iceland have in common

Answer 21

They are both hotspots

Question 22

What is the mechanism behind plate tectonics that alfred wegener didnt know of

Answer 22

CONCECTION CURRENTS

Question 23

Rifting

Answer 23

Plates spreading apart

Water eventually fills the rift and an ocean begins to form

Question 24

Define the frost shatter process

Answer 24

When water seeps into ice and freezes and expands breaking off part of the mountain or glacier

Question 25

What are some of the things that glaciers can tell us

Answer 25

All the things in the environment while the glacier formed are trapped in the glacier we can reveal that part in time when the glacier was formed

Question 26

What are depositional features glaciers

Answer 26

Till and. Drumlins

Question 27

Glacier formation

Answer 27

Snowflakes -->granular snow-->Firn-->glacier ice

Question 28

Where does old seafloor sync back into the earth to be recycled

Answer 28

Answer 31

True a subduction zone is a convergent boundary

Question 32
