Question 1
Polar climates get most of their precipitation in the ________.
◦ spring
◦ summer
◦ fall
◦ winter
◦ It is uniform throughout the year.
Question 2
Polar regions receive nearly continuous sunlight in the summer months so why doesn't the mean temperature during those months get above 10°C?
◦ The reflection of the sun's energy (albedo) by the ice and snow prevents the area from warming.
◦ The ozone layer has thinned significantly over the polar regions and this prevents heat from being trapped near the surface in those areas.
◦ The sun's energy has to heat the frozen atmosphere in order to reach the land and that takes all summer.
◦ In the summer, the winds blow from the cold oceans and keep the temperatures low.
◦ The sun is too low in the sky to be an effective heat source.
