Tectonic Hazards

Question 1

What plate boundary do Composite volcanoes form on

Answer 1

Convergent

Question 2

What plate boundary do Shield volcanoes form on

Answer 2

Divergent and Hotspots

Question 3

What is the greenhouse effect?

Answer 3

The way particles of gas (methane, carbon dioxide, nitrous oxide, water vapour) trap heat/solar radiation from the sun in the atmosphere.

Question 4

What is climate change?

Answer 4

A sustained change in the average temperature of earth over years.

Question 5

What is the enhanced greenhouse effect?

Answer 5

When human activities result in a large increase of the production of greenhouse gasses

Question 6

What is volcanism?

Answer 6

It is when some volcanoes produce so much volcanic material is partially blocks out the solar radiation.

Question 7

What are the Milankovic cycles?

Answer 7

It is the natural changes to the Earth’s orbit and position affecting how much solar radiation we receive.

Question 8

Where are earthquakes formed?

Answer 8

They are formed at plate boundaries.

Question 9

What type of pressure system is a tropical storm?

Answer 9

Low pressure weather system.

Question 10

Tropical storms form when water is at what minimum temperature?

Answer 10

27⁰C

Question 11

When does a tropical storm begin to lose energy?

Answer 11

When it reaches land.

Question 12

How will climate change impact tropical storms?

Answer 12

It will make them more powerful/intense.

Question 13

What can help track and predict tropical storms?

Answer 13

Satellite images.

Question 14

What force causes tropical storms to spin?

Answer 14

The Coriolis affect.

Question 15

What are the weather conditions at the eye like?

Answer 15

Calm and clear.

Question 16

What are natural causes of climate change?

Answer 16

Orbital change/Milankavic cycles, Volcanism,

Question 17

What can be used to measure the climate in the past?

Answer 17

Ice cores, Tree rings, Historical evidence e.g diaries, painting.

Question 18

Are warm currents at the top or bottom?

Answer 18

Warm currents are at the top, cold currents are at the bottom.

Question 19

What do the ocean currents redistribute?

Answer 19

Heat energy.

Question 20

Where do warm currents transport warm water?

Answer 20

Polewards, away from the equator. When they reach the poles, they cool and sink, because they become heavier and denser.;

Question 21

Where do cold currents transport cold water?

Answer 21

To the equator, they eventually warm, becoming less dense and then rising again.
