The Arabian Oryx
The Arabian oryx comes from the Arabian Peninsula. It has a white coat with black markings on the face, sides and legs and weighs about 100 kilos. It has two almost straight horns, side by side.
By 1972 there were no Arabian oryx left in the wild. This was because they had been hunted for their meat and because of damage to there environment. However, a zoo herd had been established in Arizona, U.S.A., in 1962. As a result, the species was saved, and today about 85 Arabian oryx have been re-introduced into the wild
The Water Cycle
The heat of the sun makes tiny drops of water evaporate from the sea. They rise into the sky and sometimes form clouds. The clouds are sometimes blown over the land .When the drops become too heavy, they fall as rain. The water becomes a river. It goes into a reservoir behind a dam. It is used in people’s houses for washing, drinking and for the toilet.
