Earth Systems Quiz

Which of the following is NOT one of Earth's spheres?

• Atmosphere

• Hydrosphere

• Lithosphere

• Biosphere

• Cybersphere

What does the term "weather" refer to?

• The condition of the atmosphere at a specific place and time, including temperature, precipitation, and wind

• The average conditions of the atmosphere over a long period of time

• The study of Earth's water and its movement

• The layers of gases surrounding Earth

Which of the following gases is NOT considered a greenhouse gas?

• Carbon dioxide (CO2)

• Methane (CH4)

• Oxygen (O2)

• Nitrous oxide (N2O)

What is the main difference between weather and climate?

• Weather describes the condition of the atmosphere over a short period of time, while climate describes average conditions over a long period.

• Climate can predict specific rain events, but weather cannot.

• Weather involves the study of oceans, but climate does not.

• There is no significant difference; they are interchangeable terms.

Which sphere of the Earth is composed of all the water on, under, and above the surface?

• Atmosphere

• Lithosphere

• Hydrosphere

• Biosphere

What is the primary cause of climate change?

• The natural rotation of Earth around the sun

• The increase in greenhouse gases in the atmosphere due to human activities

• The movement of tectonic plates

• Changes in the sun's intensity

Which of the following is a consequence of climate change?

• Decrease in global temperatures

• Increase in biodiversity

• Rising sea levels

• Decrease in extreme weather events

How do greenhouse gases affect Earth's temperature?

• They cool the Earth's surface by reflecting sunlight back into space.

• They trap heat in the atmosphere, warming the Earth.

• They have no effect on Earth's temperature.

• They increase oxygen levels, which cools the Earth.

What is the role of the atmosphere in Earth's climate system?

• It provides oxygen for humans and animals to breathe.

• It blocks all solar radiation from reaching Earth's surface.

• It regulates Earth's temperature by trapping heat.

• It contains the hydrosphere, which affects climate.

Which of the following activities contributes to an increase in greenhouse gases?

• Planting trees

• Using public transportation instead of personal vehicles

• Burning fossil fuels

• Recycling plastic materials
