Techtonic Hazards

Question 1

Three ways to describe distribution of volcanos are

Answer 1

1. Often found in lines
2. They often occur together
3. Usually on the edge of tectonic plates

Question 2

Earthquakes occur on destructive plate boundary because

Answer 2

Friction causes the tectonic plates to stick pressure builds up and is released suddenly. This triggers an earthquake as seismic waves travel through the earths crust

Question 3

Two secondary effects of earthquakes are

Answer 3

People made homeless and a result of buildings collapsed
Waterborne disease such as cholera spreads through contaminated water

Question 4

Two ways Japan as reduced the effects of tectonic hazards are

Answer 4

Designing and constructing earthquake proof buildings
Have regular evacuation drills and well signposted evacuation routes

Question 5

Three methods that can be used to monitor and predict volcano eruptions are

Answer 5

1. Seismometers
2. Tiltmeters
3. Monitor Hot Springs

Question 6

At a conservative plate boundary the plates move

Answer 6

Side by side

Question 7

Two primary effects of earthquakes are

Answer 7

Building and road damages
Burst water pipes

Question 8

To convert millimetres to centimetres

Answer 8

Divide the number by 10

Question 9

One reason why the effects from tectonic hazards are often greater in low income countries (LICs) is…

Answer 9

Emergency services tend to be smaller and they lack adequate training and access to specialist equipment.

Question 10

Tiltmeters work by…

Answer 10

Measuring the gradient of a volcano. If it increases, this could indicate the volcano is filling with magma and is about to erupt.
