What is a climatic hazard?
A climatic hazard occurs when a region has certain weather conditions. A tectonic hazard is when the Earth's crust moves

What is a tectonic hazard?
A tectonic hazard occurs when the Earth's crust moves. Examples include volcanic eruptions and earthquakes.
2 of 25
What would the likely short-term impacts of a climatic hazard be on a developing country?
'A high death toll and low economic cost. Developing countries don’t have the funds or infrastructure to help people survive hazards.
3 of 25
What factor can influence the impacts of the hazard?
Human activities can influence how often certain natural hazards occur and how severe they can be.
4 of 25
Which hazard can only occur in specific areas?
Tornadoes only occur in specific areas due to the conditions they require.
5 of 25
Which part of the Earth is found above the mantle?
The crust is the outer layer of the earth. The outer core is the layer below the mantle.

What is the name given to semi-molten rock?
Magma is semi-molten rock. Mountains are sometimes formed by magma from volcanoes (called lava).
7 of 25
What is the name given to the hot underground currents which move plates around?
Convection currents are underground movements of magma. Conservative is a type of plate margin.
8 of 25
What is the name given to margins where plates move together?
Destructive margins are where plates move together. Constructive is where they move apart.
9 of 25
What is the name given to margins where plates move apart?
Constructive plate margins are where plates move apart. Destructive is where they move together.
10 of 25
What name is given to margins where plates move side by side?
Conservative plate margins are when plates move side-by-side. Convection currents move plates.
11 of 25
Which islands are found above hot spots?
Hawaii is an arc of volcanic islands. The British Isles are located away from plate margins.
12 of 25
Where do volcanoes occur?
Volcanoes occur at constructive and destructive plate margins. There are no volcanoes at a conservative margin.
13 of 25
What is subduction?
Subduction is when the oceanic plate is forced beneath the continental plate. Two plates moving towards each other occurs at a destructive plate margin.
14 of 25
Where is continental crust found?
Continental crust is found under land masses and continents.
15 of 25
What is an earthquake?
An earthquake is a sudden and brief period of intense ground shaking. It can cause a lot of damage.
16 of 25
At which plate margins do you find earthquakes?
Earthquakes occur at all three plate margins, namely constructive, destructive and conservative plate margins.
17 of 25
What is the point in the Earth's crust where the earthquake originates known as?
The focus is the point where earthquakes originate within the Earth's crust.
18 of 25
What is the point on the Earth's surface directly above where the earthquake originates?
The epicentre is the point at the Earth's surface above the focus.
19 of 25
What piece of equipment measures earthquakes?
A seismometer measures and records details of earthquakes, such as force and duration.
20 of 25
What is an example of a primary effect?
Deaths and injuries are primary effects as they happen immediately due to the earthquake.
21 of 25
What is an example of a short-term response?
Aid from other countries is an example of a short term response - it is countries reacting quickly to the earthquake.
22 of 25
What is earthquake prediction?
Prediction attempts to forecast an earthquake. Constructing buildings is protecting the area.
23 of 25
How can buildings be adapted to cope with earthquakes?
Rubber shock absorbers fitted to absorb earth tremors are a way to adapt buildings.
24 of 25
How do people prepare for earthquakes?
People prepare by educating people on what to do in an earthquake. Earthquakes are difficult to predict and forecast.
