Unit 3- Succession/Climate Change

If Earth did not have an atmosphere, most of the energy from the sun would 

• be reflected back into space.
• be absorbed by Earth’s oceans.
• be absorbed by Earth’s landmasses.
• never reach Earth’s surface.

Which of the following is NOT a greenhouse gas?

• Water vapor
• Sulfur dioxide
• Methane
• Nitrous oxide

Which of the following is a major source of nitrous oxide? 

• Fertilizer production
• Aerosol cans
• Off-gassing of benzene from gasoline
• Metal smelting

What are the Milankovitch cycles?

• Short-term weather patterns that occur over days or weeks.

• Long-term changes in Earth's orbit and tilt that affect climate.

• The daily rotation of Earth on its axis.

• The cycle of ocean currents that influence weather.

How does the greenhouse effect influence Earth's climate?

• It decreases the amount of solar energy reaching Earth's surface.

• It traps heat in the atmosphere, leading to a warmer climate.

• It reflects solar energy back into space, cooling the planet.

• It has no impact on Earth's climate.

Which of the following best describes the relationship between Earth's orbit and climate?

• A perfectly circular orbit results in more extreme seasons.

• Variations in Earth's orbit can lead to significant climate changes over long periods.

• Earth's orbit has no impact on climate.

• A more elliptical orbit results in a constant climate.

What is the effect of volcanic eruptions on global temperatures?

• They cause long-term warming

• They cause short-term cooling

• They have no effect

• They cause long-term cooling

What is the primary cause of long-term global warming?

• Solar flares

• Greenhouse gases from human activities

• Ocean currents

• Volcanic eruptions

What happens to sunlight during a volcanic eruption?

• It remains the same

• It decreases

• It increases

• It becomes more intense

What is the effect of particles released by volcanic eruptions?

• They cause earthquakes

• They increase rainfall

• They block sunlight

• They warm the Earth
