GCSE WJEC Natural Warming and The Quaternary Period

What geological period of time are we currently in?

• Quaternary

• Archean

• Proterozoic

• Precambrian

What is the name of the following cause of climate change?

Large amount of volcanic discharge creates a blanket of ash and greenhouse gas, preventing sunlight from reaching the earth's surface.

• Eruption Theory

• Anthropogeny

• Sunspot Theory

• Orbit Theory

What is the name of the following cause of climate change?

Black areas on the sun tell us that the sun is more active. When there are more of these, more solar energy is fried out towards the earth - heating it up

• Eruption Theory

• Anthropogeny

• Sunspot Theory

• Orbit Theory

What is the name of the following cause of climate change?

The way movement of the earth throughout space influences the amount of solar energy that reaches the planet. The level of solar energy dictates the change in climate.

• Eruption Theory

• Anthropogeny

• Sunspot Theory

• Orbit Theory

Which of the following is the best conclusion that can be made from this graph?

• atmospheric carbon dioxide levels have been decreasing since 1960
• Hawaii has a lot of carbon dioxide
• humans have been working hard to decrease carbon dioxide levels
• atmospheric carbon dioxide levels have increased steadily since 1960

Visible light reaches Earth’s surface while infrared light is trapped as heat. Which characteristic of Earth’s atmosphere causes this to happen?

• the hole in the ozone
• the greenhouse effect
• atmospheric pressure
• the inversion layer

Climate is ...

• The average precipitation of a particular part of the world over an extended period of time (30 years)

• The average precipitation and temperature of a particular part of the world over an extended period of time (30 years)

• Daily changes in the amount of solar energy produced by the sun.

• Daily changes in the temperature and precipitation of a certain part of the world.

All of the following are natural sources that can change the climate except…

• Volcanoes: They release sulfur dioxide and dust particles that can reflect light.

• Changes in Solar Radiation from the Sun.

• The burning of coal and other fossil fuels by humans.

• Changes in the orbit of the Earth.

The path the earth as it orbits the Sun. This can change from circular to elliptical.

• Axial Tilt

• Solar Activity

• Orbital change

• Eccentricity

Permanently frozen ground, found in polar and tundra regions

• Frozen Ground

• Frost Bite

• Frost

• Permafrost
