(DESCRIPTION)
Text, Our sapphire-blue world has 331 million cubic miles of water.
 
3/4 of Earth cut in the form of a pie chart.
 
Text, Water covers about 75% of Earth's surface.
 
Almost all of Earth's water - about 98% - is liquid, and about 2% is stored as ice and permanent snow.
 
Earth with the continents Europe and Africa surrounded by blue water, and an area of white at the North Pole.
 
Text, Our atmosphere holds only one-thousandth of 1% of Earth's water.
 
A very small fraction of that condenses to form clouds. But it has an enormous effect on our lives.
 
Clouds high in the sky range in size and shape, from wispy to fluffy.
 
On the surface of Earth, clouds move in spiral motions in various directions.
 
Text, Clouds influence weather and climate.
 
Clouds carry water from one region of the planet to another.
 
Clouds also regulate Earth's temperature by absorbing and reflecting sunlight, and by trapping heat.
