1A 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
