Precipitation

Precipitation is caused when moist air rises, water vapour in the air cools  and  condenses  to forms clouds. Air cools upwards through the atmosphere because temperature falls with altitude because the Earth’s atmosphere is heated from the Earth’s surface up over. When the water droplets in clouds grow to a certain size, gravity causes them […]

The materials on the beach vary in size from fine sand to pebbles . The waves sort these materials according to the weight. The finer sand deposited […]
