Q

What is a Ferrel Cell?

A

At around 60° North and South of the equator, moist air rises, and travels to lower latitudes at around 30°. Here, it sinks along with air travelling from the equator.

Q

What are Greenhouse Gases?

A

Gases in the Earth’s atmosphere that trap energy in the Earth’s system and contribute to the greenhouse effect.

Q

What is a Hadley Cell?

A

Warm, moist air rises near the equator and then cools as it travels to higher latitudes (30°) where it sinks.

Q

What is an Ice Core?

A

A cylinder of ice extracted from an ice sheet or glacier, which is used to analyse past environmental conditions.

17
Q

What are Immediate Responses?

A

Actions taken as soon as the hazard occurs and in its immediate aftermath.

18
Q

What is the Intertropical Convergence Zone (ITCZ)?

A

An area surrounding the equator where global winds converge, causing an area of low pressure with rainy conditions.

19
Q

What are Long-term Responses?

A

Actions taken after the immediate responses when the effects of the hazard have been minimised.

20
Q

What is Meteorological Drought?

A

When the amount of precipitation received in an area is below average.

21
Q

What are Milankovitch Cycles?

A

The cyclical variations in the Earth’s orbit around the Sun.

22
Q

What are Ocean Currents?

A

The predictable, continuous circulation of ocean water which transfers heat around the globe.

23
Q

What is a Polar Cell?

A

At 60° north or south of the equator, moist air rises, and travels to the poles (90°), where it sinks.

24
Q

What is a Pressure Belt?

A

A region of the Earth which is generally under the same pressure.

25
Q

What are Primary Effects?

A

The effects that are directly caused by the hazard itself.

26
Q

What is the Quaternary Period?

A

The geological time period which began 2.6 million years ago and extends into the present.

27
Q

What are Secondary Effects?

A

Impacts that are a result of the primary effects of a hazard.

28
Q

What is a Storm Surge?

A

When a tropical cyclone pushes a large amount of sea water onto the shore, causing a rise in sea level.

29
Q

What is Subduction?

A

A process that occurs at a destructive plate boundary when a plate is pushed below another plate.

30
Q

What is The Enhanced Greenhouse Effect?

A

A process where the Earth’s surface is heated by the greenhouse effect at an increased rate due to larger greenhouse gas emissions from human activities.

31
Q

What is The Greenhouse Effect?

A

A natural process where greenhouse gases trap the energy from the Sun inside the Earth’s atmosphere, warming the Earth’s surface.

32
Q

What is a Track in relation to tropical cyclones?

A

A typical pathway that a tropical cyclone takes which is driven by global wind circulation.

33
Q

What are Tree Rings?

A

A ring in a tree trunk that grows annually, indicating the conditions in the year it grew.

34
Q

What is a Tropical cyclone?

A

A very large, spinning storm with high winds and torrential rain that forms in the tropics.

35
Q

What is a Typhoon?

A

A tropical cyclone that hits India, Japan or the Philippines.
