Atmospheric System Aim- Explain with the aid of an annotated diagram the global Heat Budget.

1. Atmospheric SystemAim- Explain with the aid of an annotated diagram the global Heat Budget. Tasks; • Read page 5 of the Higher textbook. • Make a copy of the diagram opposite. • Using figure 2.2, describe the distribution of solar energy in the earth-atmosphere system. 8 marks. • What is the earth’s ALBEDO? 4 marks 6% reflected by earth’s surface 52% 46% absorbed at the surface.

2. Atmospheric SystemAim- Explain with the aid of an annotated diagram the global Heat Budget. • 100% enters the earth/atmospheric system. 23% of those is initially absorbed by the atmosphere, 4% by clouds and 19% by water vapour, gases and dust. 25 % is also reflected by atmosphere, 17 % by clouds and 8% by gases and dust. This leaves 52% heading towards the earth’s surface, where 46% is absorbed by the surface and 6 % is reflected. The total energy lost at this point is 31% known as the earth albedo (total amount reflected).
