Unit 1: Section A

Question 1

What is a natural hazard?

Answer 1

-A natural event that can cause damage to people and property.

Question 2

What are the types of natural hazards?

Answer 2

-Geological(caused by tectonic processes)
-Meteorological(caused by weather/climate)

Question 3

What are some factors affecting hazard risk?

Answer 3

-vunlerability=the more people in areas exposed to natural hazards, the greater chance of them being affected.
-capacity to cope=the better a population can cope, the lower the threat.
-Nature of the natural hazard(type, frequency and magnitude).

Question 4

What are tectonic plates?

Answer 4

-Earth’s surface is split into slabs called tectonic plates(either oceanic or continental).
-These plates are moving because of convection currents below the mantle.

Question 5

What are the 4 types of plate boundaries?

Answer 5

-Destructive
-Constructive
-Collision
-Conservative

Question 6

What is a plate margin?

Answer 6

-The place where plates meet.

Question 7

What are the 4 types of plate boundaries?

Answer 7

-Destructive
-Constructive
-Collision
-Conservative

Question 8

What is a destructive plate boundary?

Answer 8

-when an oceanic and continental plate move towards eachother, the oceanic plate subducts under the continental since it’s dense.
-the oceanic plate beings to melt, forming magma

Question 9

What is a constructive plate boundary?

Answer 9

-When 2 plates move away from eachother

Question 10

What is a collision plate boundary?

Question 11

What is a conservative plate boundary?
