What is the primary source of water on earth?
rainfall
How did the desert soil get salty?
During years of heavy rainfall in the distant past, enough water accumulated in basins found throughout the Andes to create lakes. Some of the lakes got their water from melting glaciers at the end of the last ice age. But in some lakes in the Andes mountains, such as Atacama, more water is lost through evaporation than is replaced by rainfall so the lakes are drying up. As the water evaporates, the mineral salts in the water become more concentrated, creating very salty water.
What is convectinal rainfall?
There are many different types of rainfall and convectional is simply one type. It refers to the way the sun heats the water, creating water vapor that rises into the sky.
Does heavy rainfall make ocean water more or less dense?
Heavy rainfall makes water less dense because an increase in salinity leads to an increase in density. Rain does not contain any salt. Therefore heavy rainfall makes ocean water less dense. =)
Why rainfalls are so immportant?
Rainfall is a important part of water cycle that we have studied in our earlier classes. Without rainfall, how would water that gets evaporated from water bodies will be back to their origin. Rainfall occurs because water droplets that constitute clouds gets so big in size that they no longer can be in air and falls down in form of rain.

What is one centimeter of water?
centimetres cubed. centimetre is distance, squared is area, cubed is volume. 1cm3 of water is 1millilitre of water. And with density being near 1g/cm3, 1ml of water is 1 gram (weight) If someone says the rainfall has been 1cm (more commonly rainfall is measured in mm) it means that a depth of rainfall of that amount has occurred. Otherwise it means that the depth of water in a location is 1 cm.
