I WONDER - What Is A Polar Ice Cap?

The video explains the role of Earth's polar ice caps as reflective shields, crucial for maintaining the planet's temperature balance. It highlights the albedo effect, where ice caps reflect solar radiation, cooling the Earth's surface. An analogy of wearing a white T-shirt on a sunny day illustrates how surface color influences temperature.

What function do the polar ice caps serve for Earth?

• They are only present in the summer.

• They absorb solar radiation.

• They increase Earth's temperature.

• They act as Earth's reflective shields.

Which of the following statements is true about the Arctic ice cap?

• It is smaller than the Antarctic ice cap.

• It is located in the Southern Hemisphere.

• It floats on the Arctic Ocean.

• It sits on a continent.

How do the polar ice caps help in maintaining Earth's temperature balance?

• By increasing the Earth's albedo.

• By melting during the summer.

• By reflecting solar radiation back into space.

• By absorbing heat from the sun.

What is the albedo effect?

• The absorption of solar radiation by ice.

• The reflection of solar radiation by ice.

• The melting of ice caps.

• The increase in Earth's temperature.

How is the albedo effect similar to wearing a white T-shirt on a sunny day?

• Both absorb heat.

• Both reflect light to stay cool.

• Both are unrelated phenomena.

• Both increase temperature.
