Description : Air over the oceans is colder in summer and warmer in winter compared with air over the continental regions. This is because (a) Water is translucent and has a relatively high heat capacity compared ... B are true (e) The effect is due to the changes in circulation between continents and oceans
Last Answer : (d) Both A and B are true
Description : Increasing carbon dioxide will cause sea ice to reduce in spatial coverage. In turn, the reduced sea ice extent is a (a) Positive feedback on surface temperature because it has a greater albedo than ocean ( ... because sea ice has lower heat ca- pacity than ocean (d) Both B and C are true
Last Answer : Positive feedback on surface temperature because it has a greater albedo than ocean
