Albedo and Climate

Which of the following is evidence that global warming is a positive feedback loop?

• Global warming creates changes that slow down the warming of Earth.

• Global warming melts glaciers which decrease albedo, leading to increased sunlight absorption.

• Global warming melts glaciers which increases albedo, leading to increased sunlight absorption.

• Global warming melts glaciers, cooler temperatures increases albedo, leading to decreased sunlight absorption.

What is the relationship between albedo and Earth's temperature?

• As albedo increases, temperatures decrease.

• As albedo decreases, temperatures decrease.

Which of the following surfaces/objects has the highest albedo effect?

• Sand

• Snow/Ice

• Oceans

• Forests

Volcanic eruptions cause climate change by

• reflecting sunlight and therefore decreasing temperatures

• absorbing sunlight and therefore increasing temperatures

• polluting the earth causing global warming

• reflecting sunlight and therefore increasing temperatures

Albedo is a measure of surface reflectivity. The polar albedo is important because:

• It reflects greenhouse gases, cooling our planet

• It absorbs solar radiation, which melts snow

• It reflects solar radiation back into space, cooling earth

• It absorbs greenhouse gases, pulling them out of circulation

An important example of a "positive feedback loop" in the polar climate system is:

• Scientists in remote places check on each others instruments

• Warming ocean water opens new areas for marine species

• Warmer winters cause more plant growth, providing more food

• Sea ice melt opens more ocean to sunlight, causing more melt

Which of the following surfaces has the HIGHEST albedo?

• Aluminum foil

• A sheet of dark coloured paper

• Fresh snow

• A field of grass

Which of the following best describes the concept of albedo in climate science?

• The measure of the reflectivity of Earth's surface.

• The amount of carbon dioxide in the atmosphere.

• The rate of evaporation from oceans.

• The speed of wind currents.

How does a decrease in Earth's albedo affect global temperatures?

• It leads to an increase in global temperatures.

• It causes a decrease in global temperatures.

• It has no effect on global temperatures.

• It stabilizes global temperatures.
