Rain
Rain is created when it is usually warm outside. The Water from the tops of lakes and oceans evaporates creating clouds. Warm air holds more water then cool air so when the warm air in clouds cools down all the moisture condenses and creates rain. The moist air forms into rain until the rain drop gets heavy enough to fall to the ground. The water that falls from the clouds usually ends up in the clouds again. This is known as the water cycle.
