Question 2

What is the lithosphere

Answer 2

The outer solid part of the earth includes the crust and uppermost mantle

Question 3

What is the core and it’s two parts?

Answer 3

Inner core

• about 1400km from the centre out
• solid nickel and iron
• high pressure and temp 10000 degrees c

Outer core

• 2000-2400km thick
• liquid composed of mostly iron
• temp 2000-6500 degrees

Question 4

The inner mantle

Answer 4

• Also called the mesosphere
• 1900km thick
• gets increasingly rigid outwards
• composed of silicon, manganese and iron oxides

Question 5

Outer mantle

Answer 5

• 900km thick
• semi plastic
• bottom portion called the asthenosphere
• source of lava and magma coming to the surface
• contains “mohorovicic break” which is the area between mantle and crust

Question 6

Oceanic crust

Answer 6

• 7-10km thick
• Age of less than 200 million years
• Composed of silica (sand), iron and magnesium
• referred to as “SIMA”

Question 7

Continental crust

Answer 7

• 40km think
• older than 1500 million years
• composed of silica and aluminum
• region of plate tectonics and continental drift

Question 8

Answer 8

Basalt plateau
Shield 
Cinder come 
Composite 
Caldera

Question 9

P waves

Answer 9

P stands for primary waves
Fastest wave
Travels deep below the surface of the earth
Compression waves

Question 10

S waves

Answer 10

Second fast wave
Travel deep below the surface of earth
Shear wave (side to side)

Question 11

L wave

Answer 11

Surface wave
Slowest most damaging
Moves over the surface of the earth like and ocean wave
Causes the lifting of Rock at surface

Question 12

Karst topography

Answer 12

Areas of the world with feature defined by the erosion of limestone bedrock

• the erosion of limestone by water occurs through a basic chemical reaction
• water and limestone for a mild acid that erodes limestone which is chemical weathering

Question 13

Glacier features (cirque)

Answer 13

Bowl shaped valley created when ice moves out from an area

Question 14

Glacier feature (horns)

Answer 14

Pyramid like peaks formed from Several cirques

Question 15

Glacier features (Aretes)

Answer 15

ridges firmed from two back to back cirques

Question 16

Glacier features (tarn)

Answer 16

Small lake found within a cirque

Question 17

Moraines

Answer 17

Deposits of material picked up and carried by ice then deposited
Material is know as till

• lateral- alongside the glacier
• terminal is at the end

Question 18

Continental glacier features (erratic)

Answer 18

Boulders lifted by ice

Question 19

Continental glacier features (Drumlins)

Answer 19

Small hills of sediment formed from ice re-advancing over at existing Moraine. Tell is deposited as glaciers cannot carry that much settlement/material

Question 20

Continental glacier features (striations)

Answer 20

Scraping in rocks surface

Question 21

Continental glacier feature (kettle lakes)

Answer 21

Small lakes left when large chunks of ice break off and melt
