Hi my name is sun and I cause day, night, and seasons! I cause day time because my bright sun rays hit Earth and give it light
Hi my name is the moon and I don't really cause day and night, but I do cause high and low tides
Hi my name is the Earth, and I cause day and night...well not exactly. The sun produces the light but I make sure it's not always day time. I rotate on my axis, which is tilted, and that makes the sunlight hit different places, or hemispheres, at different times.
Gravity is the force that attracts a body toward the center of the earth
The Law of universal gravitation is the attraction between two objects
My gravitational pull is so strong I make every planet around me revolve around me.
My gravitational pull is what keeps everybody on Earth from flying away, and it also makes the moon revolve around me.
