Mini-Quiz: Heat Transfer on Earth

1. How can you tell that the effect of heat from the core is not significant?

   It is significant and the only source of heat on the EarthSorry, not correct. Try another button. The temperature of the Earth's core is only 75°Good try, but not right. Select another answer. The Earth gets cold during the winter monthsThat is correct. You understand about heat and the Earth.

2. Why is radiation from the Earth a greater factor in heating air than radiation from the Sun?

Visible light from the Earth is closer to the air and thus heats it betterSorry, not correct. Try another button.

3. Could a large volcano eruption stop global warming?

   Yes, because the excess dust in the air could compensate for the excess of infrared-absorbing gassesThat is correct. You understand about heat and the Earth. It depends if the eruption came in the winter or the summerGood try, but not right. Select another answer. No, because a volcano eruption would only increase global warming due to the heat of the eruptionOops! Wrong answer. Re-read the question and try again.
