Geography

Question 1

Answer 1

The meeting of two tectonic plates

Question 2

What is an Active Volcano

Answer 2

A volcano which is likely to erupt or has erupted

Question 3

What is MEDC

Answer 3

More Economically Developed Country

Question 4

What’s it called when Plate Boundaries move TOWARDS each other

Answer 4

Convergent

Question 5

Why would people live near a volcano

Answer 5

• Fertile Soil
• Geothermal Power
• Resources (Sulphur)
• Tourism
• Cannot afford to move

Question 5

What’s it called when Plate Boundaries move APART from each other

Answer 5

Divergent

Question 6

Name the 3 Tectonic Plates

Answer 6

Divergent
Convergent
Transformative

Question 7

What causes a volcano?

Answer 7

Plate boundary movement
Convection current in mantle

Question 8

Name scale to measure earthquake

Answer 8

Richter

Question 9

Name 4 types of Volcano

Answer 9

Shield
Stratovolcanoes
Volcano Domes
Cinder Cones

Question 10

Whats another name of a transformative boundary

Answer 10

Conservative

Question 11

Whats another name of a CONVERGENT boundary

Answer 11

Destructive
Collision

Question 12

Whats another name of a DIVERGENT boundary

Answer 12

Constructive (a new crust is created)

Question 13

What happens at a convergent boundary?

Answer 13

Plates collide
Sometimes subduct (eg Oceanic)
Build up of Magma, Magma rises and lava solidifies

Question 14

How does rock type affect an earthquake

Answer 14

• How fast they lose energy
• For instance, very solid granites will transmit energy better than the rocksand rubbble

Question 15

How do fold mountains occur?

Answer 15

• Fold mountains are created when tectonic plates are pushed together (convergent plate boundaries)
• At these colliding, compressing boundaries, rocks and debris are pushed and folded into hills, mountains, and entire mountain ranges.

Question 16

Composite or StratoVolcano
Volcano

Answer 16

• Convergent Plate
• Viscous (sticky) lava
• Steep sides as the lava doesn’t flow very far before it solidifies.
• Layers of ash and lava.
• The name stratovolcanoes referes to Strato means layers.
• Violent eruptions.
• Longer periods between eruptions.

Question 17

Describe Shield Volcanoes

Answer 17

• On divergent or Constructive plate boundaries
• Basic lava, very runny
• Gentle sides as the lava flows for long distances before it solidifies
• No layers, as the volcano just consists of lava
• Less violent eruptions
• Shorter periods between eruptions

Question 18

How is earthquake damage linked by depth

Answer 18

• The depth of an earthquake significantly influences its impact on the surface
• Shallower quakes generally causing more damage.
• The depth of an earthquake **(focal depth) **is a critical factor in determining the level of destruction it can cause on the Earth’s surface.

Question 19

What 5 factors impacts the damage of an earthquake?

Answer 19

• Intensity
• Duration of the shaking
• Rock Type
• Building type
• Population density

Question 20

How is earthquake damage linked to population density

Answer 20

• High population density areas are more vulnerable to damage
• There are more buildings/ structures that can be impacted.
• Higher likelihood of building collapse
• In poorer areas buildings may not be earthquake proof

Question 21

In the earth structure where do the tetconic plates sit?

Answer 21

The lithosphere.
