Describe two ways in which the climate at the top of a mountain range will be different to that of the surrounding lowland areas. (2%)
(a)
In general, it gets colder as you move from the equator to the poles. Give two reasons to explain why the energy from the sun is strongest at the equator and weakest at the poles. (4%)
Answer: 1
In equatorial areas, the sun is overhead for the majority of the year and its energy passes through narrow part of the atmosphere. In polar areas, the sun’s energy passes through a thicker layer of atmosphere. It also strikes the earth at a low angle and some energy is lost by reflection back into space.
