TBSHS Geography GCSE. Weather hazards and climate - Quiz 2

What is climate change?

• The current rise in the average temperature of Earth's air and oceans

• How the average climatic conditions of the planet vary over time

• The long-term pattern of weather in a particular area

• It describes the day-to-day conditions of the atmosphere

A geological time period that encompasses the most recent 2.6 million years, including the present day.

• Jurassic

• Quaternary

• Cretaceous

• Holocene

An interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances.

• Glacial

• Interglacial

• Climate change

• Quaternary

Periods of warmer climate between glacial periods:

• Glacial

• Interglacial

• Climate change

• Quaternary

Natural causes of climate change

Natural changes to the Earth's orbit and position that affect how much radiation we receive from the Sun:

• Nuclear reactions

• Astronomy

• Sunspot activity

• Milankovitch cycles

Natural causes of climate change

There are THREE types of Milankovitch cycles:

• Eccentricity

• Precision

• Precession

• Axial tilt

Natural causes of climate change

Select the natural cause(s) of climate change

• Solar variation (sunspots)

• Tree rings

• Volcanic eruptions

• Ice cores

Natural causes of climate change.

A large-scale volcanic eruption can eject ash and dust into the atmosphere.

This can cause...

• short-term global cooling

• It has no impact on the Earth's climate

• short-term global warming

• a change in the Earth's orbit around the Sun

Evidence of climate change

The most reliable source of evidence in the last 150 years:

• Tree rings

• Ice cores

• Thermometer records

• Pollen records

Evidence of climate change

Tree rings tend to be...

• thinner in warmer, wetter climates

• wider in warmer, wetter climates

• wider in colder, drier climates

• thinner in colder, drier climates
