G1A Tectonic Hazards

Question 1

Tectonic Hazard

Answer 1

Natural hazard that has occured due to movement of tectonic plates.

Question 2

Continental/Oceanic Crust

Answer 2

Continental-Makes up the land, old less dense thick
Oceanic- makes up seafloor, younger, dense,thin

Question 3

Layers of the earth

Answer 3

Crust-Plates
Mantle-Magma
Outer Core-Liquid iron/nickel
Inner core-Solid iron/Nickel

Question 4

How do plates move

Answer 4

With convection currents in the mantle that circulates magma around the earth moving the plates.

Question 5

3 types of plate margins

Answer 5

Constructive-Plates move away
Destructive-Plates move towards
Conservative-Plates move alongside

Question 6

Constructive

Answer 6

Plates move away allowing for magma to flow out forming volcanoes. Can be on continental/oceanic crust

Question 7

Destructive

Answer 7

Plates move towards each other forming. Causing one plate to subduct below the other. The pressure causes deep earthquakes which then leads to magma exploding out causing volcanoes. Oceanic sinks continetal rises. Fold mountains

Question 8

Conservative

Answer 8

They move side by side and they create friction. Earthquakes that can displace water and cause tsunamis

Question 9

Hotspot

Answer 9

When magma breaks through a hole in the crusts surface and magma seep through

Question 10

Hazard Managment

MPPP

Answer 10

Monitoring- Detecting/recording physical changes like temperature and gas produced
Predicting- Historical trends allow us to see when volcanoes will occur again
Planning- Regular practice of evacuation routes like fire drills
Protection- Earthquake proof buildings

Question 11

3 factors for living near earthquakes

Answer 11

Social- Family and friedns may live in the area
Economic- Jobs may pay more in that specifc area.
Enviromental- Land is very fertile near volcanoes so agriculture can occur
