The process through which heat passes from warmer to colder substances as long as temperature difference exists, is known as

1. Convection
2. Conduction
3. Radiation
4. Advection

3. Poles get extremely slanting rays of the sun.
4. All the above

'Latitude is one of the important factors for controlling the temperature' — which of the following fact justifies this statement?

1. The hill stations are cooler even in summer.
2. The areas in the high latitude are not very hot as compared to the equatorial regions.
3. Areas close to water bodies have low diurnal and annual range of temperature than the areas situated far away from the coast.
4. All the above

'Forest areas are cooler than the open places'- which of the following reasons is responsible for it?

1. Forests receive more slanting rays of the sun than the open areas.
2. All the forests are situated in the higher latitudinal areas.
3. The vegetation cover checks the radiation from the upper layer of the soil.
4. Forests are mainly situated in the mountains
