08 Earth's Climate and Environmental Influences

How does Earth's climate get affected by the angle of incoming light?

• It remains constant regardless of the angle.

• The angle affects the amount of solar energy received.

• The angle only affects the temperature at the poles.

• The angle has no impact on atmospheric circulation.

What role does the atmosphere play in Earth's climate?

• It has no effect on climate.

• It only affects the weather, not the climate.

• It helps distribute energy and influences phenomena like auroras.

• It solely protects Earth from meteors.

What is the "Great Oxygenation Event" linked to?

• The extinction of dinosaurs.

• The origin of atmospheric oxygen and photosynthesis.

• The formation of the ozone layer.

• The beginning of the ice age.

How do coral reefs and mangroves influence Earth's surface features?

• They have no significant impact.

• They contribute to soil development and biodiversity.

• They only affect marine life.

• They prevent volcanic eruptions.

What is the relationship between carbon dioxide levels and the greenhouse effect?

• Carbon dioxide levels have no impact on the greenhouse effect.

• Increased carbon dioxide levels enhance the greenhouse effect, raising global temperatures.

• Decreased carbon dioxide levels enhance the greenhouse effect.

• The greenhouse effect only depends on methane levels.

What is a common indicator that the Earth's surface temperature is increasing?

• Decrease in ocean temperatures

• Increase in polar ice caps

• Increase in Earth's surface temperature

• Decrease in global temperatures

What does the map titled "Temperature change in the last 50 years" illustrate?

• Decrease in global temperatures

• Increase in global temperatures

• No change in global temperatures

• Decrease in ocean temperatures

According to the graph, how has the average sea temperature changed since 1890?

• It has decreased significantly

• It has remained constant

• It has increased

• It has decreased slightly

What is the total amount of solar radiation reaching Earth from the Sun?

• 174 petawatts

• 200 petawatts

• 150 petawatts

• 100 petawatts

How much solar radiation is absorbed by land and oceans?

• 51%

• 23%

• 19%

• 6%
