Natural Climate Change Quiz

What was the Earth's climate like before the Quaternary period?

Warm and quite stable

Cold and quite stable

Warm and unstable

Correct! Wrong!

True or false? During the Quaternary, global temperature has shifted between cold glacial periods that last for around 100,000 years and warmer interglacial periods that last for around 10,000 years.

True

False

Correct! Wrong!

Which of the following statements best describes the Earth's climate since the last glacial period around 15,000 years ago?

The climate has remained stable since the last glacial period.

The climate has been warming since the last glacial period.

The climate has got colder since the last glacial period.

Correct! Wrong!

Which of the following is not a source of evidence for natural climate change?

Ice cores

Tree rings

The Internet

Historical sources

Pollen records

Correct! Wrong!

Identify the source of evidence for natural climate change described below. By analysing the gases trapped in layers scientists can calculate what the temperature was each year.

Tree rings

Ice cores

Historical sources

Pollen records

Correct! Wrong!

Identify the source of evidence for natural climate change described below. Scientists take cores and count the rings to calculate the age of the flora. The thickness of each ring indicates what the climate was like.

Pollen records

Tree rings

Historical sources

Ice cores

Correct! Wrong!

How can pollen be used to determine historical climate?

Scientists can identify and date preserved pollen to show which species were living at that time. Scientists are able to analyse the molecules of the pollen to determine the temperature of the time of their formation.

Scientists can identify and date preserved pollen to show which species were living at that time. Scientists know the conditions plants live in now, so preserved pollen from similar plants shows that climate conditions were similar.

Scientists can identify and date preserved pollen to show which species were living at that time. The size of pollen are determined by the climate at the time. By measuring pollen scientists can identify the characteristics of the climate when it was formed.

Correct! Wrong!

Which of the following is not an example of a historical source of evidence for natural climate change?

Diaries

Paintings

Ice core

Correct! Wrong!

Which of the following is an example of a natural cause of climate change?

Malkovich Cycles

Milankovitch Cycles

Melkankovitch Cycles

Correct! Wrong!

True or false? Milankovitch Cycles are variations in the way the Sun moves as it orbits the Earth.

True

False

Correct! Wrong!

Milankovitch Cycles are variations in the way the Earth moves as it orbits the Sun.

Which of the following is not an example of a feature of Milankovitch Cycles?

Stretch

Tilt

Wobble

Variation

Correct! Wrong!

True or false? Milankovitch Cycles affect how far the Earth is from the Sun, and the angle that the Sun's rays hit the Earth. This changes the amount of solar radiation the Earth receives. The more energy it gets the warmer it is.

True

False

Correct! Wrong!

The tilt, or axis changes of the Earth changes over a cycle of how many years?

12,000 years

22,000 years

32,000 years

Correct! Wrong!

True or false? Orbital changes may have caused glacial and interglacial cycles of the Quaternary period.

True

False

Correct! Wrong!

What is solar variation?

Changes in the output of the Sun's energy, following short cycles of about 11 years.

Changes in the input of the Sun's energy, following short cycles of about 11 years.

Changes in the output of the Sun's energy, following short cycles of about 20 years.

Correct! Wrong!

What causes solar variation?

Sunegym

Sunshade

Sunspots

Correct! Wrong!

Which of the following best describes what a sunspot is?

A cooler area of the Sun's surface.

A hotter area of the Sun's surface.

Correct! Wrong!

True or false? Volcanic activity may cause long-term changes in climate.

True

False

Correct! Wrong!

Volcanic activity may cause short-term changes in climate.

How do volcanic eruptions cause natural climate change?

Material erupted into the atmosphere reflects the Sun's rays back out to space, so the Earth's surface cools.

The hot, volcanic material ejected into the atmosphere causes atmospheric warming, leading to natural climate change.

Material released into the atmosphere allows energy from the Sun to pass through it. However, reflected energy from the Earth's surface is trapped, causing temperatures to rise.

Correct! Wrong!

True or false? Climate change only occurs as the result of natural causes.

True

False

Correct! Wrong!

Natural Climate Change Quiz

Well done! You have a great understanding of this area of geography!

Not a bad effort at all, but you should consider revising this area a bit more.

Hmmmmmm, you might want to spend some time revising this area of geography.
