Natural Events Impact on Climate Change

What is the role of greenhouse gases in the Earth's climate?

• They help keep the Earth’s temperature stable by trapping heat.

• They reflect sunlight away from the Earth, causing cooling.

• They are released only during volcanic eruptions.

• They react in the atmosphere to distribute nutrients and warmer climates throughout Earth.

How can changes in ocean currents influence climate?

• They cause volcanic eruptions.

• They have no impact on the climate.

• They only affect the weather in coastal areas.

• They can change temperature patterns, making some areas warmer and others cooler.

How does the release of sulfur dioxide during a volcanic eruption affect the climate?

• It makes the oceans warmer.

• It has no effect on the Earth's climate.

• It causes the Earth to warm by absorbing more sunlight.

• It forms tiny particles in the atmosphere that reflect sunlight, leading to cooling.

How do volcanic eruptions impact the climate in the short term?

• They cause long-lasting global warming.

• They lead to immediate long-term cooling.

• They cause short-term cooling by blocking sunlight with ash and gases.

• They result in a temporary increase in temperature.

What evidence supports the answer of the cause for a short-term cooling?

• Meteorite impacts cause long-term cooling, while disrupted ocean currents cause short-term cooling.

• Long-term cooling from ocean currents would lead to gradual temperature changes over many years, while meteorite impacts cause a quick drop in temperatures.

• Both would cause immediate and permanent global cooling.

• There is no difference; both cause similar types of cooling.

What effect does increased melting ice in Greenland have on the Gulf Stream?

• It strengthens the Gulf Stream.

• It disrupts the Gulf Stream.

• It has no effect on the Gulf Stream.

• It reverses the Gulf Stream.

What type of water is added to the Gulf Stream due to melting ice?

• Warm, salty water

• Fresh, cold water

• Hot, fresh water

• Salty, cold water

How do volcanic eruptions impact the climate in the short term?

• They cause long-lasting global warming.

• They lead to immediate long-term cooling.

• They cause short-term cooling by blocking sunlight with ash and gases.

• They result in a temporary increase in temperature.

What is one difference between the effects of greenhouse gases and volcanic eruptions?

• Greenhouse gases cause short-term cooling.

• Volcanic eruptions cause long-term warming.

• Greenhouse gases cause long-term warming, while volcanic eruptions cause short-term cooling.

• Both have the same effect on climate.
