Explanation Writing - The Water Cycle

This is how the hydrosphere goes round. First water molecules get evaporated by the sun and turn to gas. The water molecules source is the sea, lakes or rivers. As the molecules get higher they bunch together and form a cloud. When the clouds get too full the water molecules come out as rain, snow, sleet or hail. This is known as precipitation. Infiltration is when the rain goes into the ground. This water is called ground water and can stay in the ground for few days to thousands of years. Sometimes when it rains heavily the rain goes over cliffs by rivers, lakes or the sea. This is called run off. All the water is returned to the sea so it can repeat its process.
