8.11A/C Natural Events and Climate/Carbon Cycle

Multiple Choice

How does the release of greenhouse gases influence Earth's climate?

• It causes the Earth to cool down.

• It leads to an increase in Earth's temperature.

• It has no effect on climate.

• It reduces the amount of sunlight reaching Earth.

Multiple Choice

What is a potential consequence of the absorption of greenhouse gases?

• Decrease in global temperatures.

• Increase in global temperatures.

• Stabilization of climate patterns.

• Reduction in ocean currents.

Multiple Choice

Complete the following statement using one of the choices below. The carbon cycle is–

• nature’s way of reducing the amount of carbon available.

• nature’s way of neutralizing toxic carbon.

• nature’s way of recycling carbon.

• nature’s way of eliminating carbon.

Multiple Choice

How do volcanic eruptions influence climate?

• They decrease the amount of sunlight reaching the Earth's surface.

• They increase the Earth's temperature by releasing heat.

• They have no effect on the climate.

• They cause immediate cooling by releasing cold gases.

Multiple Choice

Which of the following is a result of a meteor impact on Earth's climate?

• Increase in ocean currents.

• Decrease in atmospheric pressure.

• Release of dust and aerosols that block sunlight.

• Increase in greenhouse gas absorption.

Multiple Choice

9. The map below shows ocean currents in one part of the world. 

10. Predict what would happen if an abrupt change in this ocean current cooled the current down significantly due to climate change. 

• Europe would experience wetter weather. 

• Europe would become hotter. 

• 1. Europe’s climate would stay the same. 

• Europe would be colder.

Multiple Choice

What role do ocean currents play in climate regulation?

• They have no role in climate regulation.

• They distribute heat around the planet.

• They only affect the climate near coastlines.

• They increase the Earth's temperature uniformly.

Multiple Choice

How is climate influenced by ocean currents?

• 1. Ocean currents reflect the Sun’s heat back out into space, regulating climate. 

• 1. Ocean currents bring colder water to the tropics and carry warm water toward the poles, warming air temperatures. 

• 1. Ocean currents absorb heat, keeping the planet warm enough to support life.

• Ocean currents bring warm water from the poles to the regions on the equator, which causes a warm, tropical climate. 

Multiple Select

7. Some natural events tend to have a warming effect on the planet, and some tend to have a cooling effect. Select the events that have a warming effect.

• Meteor Impacts

• Ocean Currents

• Volcanic Eruptions

• Release and absorption of greenhouse gases

Multiple Choice

How do greenhouse gases affect Earth’s climate?

• 1. They create clouds that produce acid rain. 

• 1. The particles reflect sunlight and heat back out into space, keeping the planet cooler. 

• 1. They let heat radiate out into space like open windows ventilate a house. 

• They work like windows, trapping heat closer to Earth’s surface instead of letting it radiate out into space.
