Explanation about
Rainfall is the amount of water that falls on a flat
surface during a certain period measured in millimeters (mm) in height above
the horizontal surface. Rain can also be interpreted as the height of rainwater
collected in a flat, non-evaporating, non-absorbing and non-flowing place
Precipitation is a vital component of how water moves through earth's water cycle, connecting the ocean, land, and atmosphere. knowing where it rains, how much it rains and the character of the falling rain, snow or hail allows scientists to better understand precipitation's impact on streams, rivers, surface run off and ground water. freequent and detailed measurements help scientist make models of and determine changes in Earth's water cycle
EXPLANATION TEXT ABOUT WHY THE SEASON CHANGE
The Earth axis in an imaginary line running between the north and south poles. Each day, the earth makes one full rotation on it's axis. This rotation take 24 hours, which we call one day. While the earth busy turning daily circles, it is also travelling along a giant oval path around the sun. This path is called earth's orbit. it takes our planet 365 days to make one complete trip around the sun. In Fact, that trip around the sun is how we define one year. The tilt means that, on any given day, th earth is slightly pointed toward or away from the sun. As the earth travels around the sun over the course of a years and the tilt of it's axis points your hemisphere toward or away from the sun, you experience the changing of the seasons.
