1.Because of the Earths daily rotation it causes the sun to appear to rise in the east and set in the west so it creates a day and night so the moon relies on the sun to set and rise during a certain time in the hemisphere 2.The seasons result from the 23.5-degree tilt of the Earth's axis combined with its revolution around the sun 3.The Moon's and Sun's gravitational pulls on Earth are responsible for this natural phenomenon creating the tides. Tides occur because the Moon's gravity decreases with distance from the Moon. 4. A lunar eclipse occurs when the Earth is positioned directly between the Sun and the Moon and the Earth casts a shadow on Moon. A solar eclipse happens when the moon is positioned directly between the Earth and the Sun and the Earth passes into the shadow of the moon. 5. The Earth depends on …show more content…
The shape of the planets is a result of gravity. Gravity is responsible for holding everything together. Without it,the entire universe would be different. 2.They differ greatly in size; the Sun is much larger than the Moon. While the Sun is a star made of gas, the Moon is rock. The Sun does not move, but the Moon does. They both affect the Earth in different ways 3.I would say that the Sun is the strongest force. It has the largest gravitational pull.The Moon and the Earth both depend on the Sun for different things, and the Sun is not greatly affected by either the Moon or Earth 4.Astronauts experience weightlessness on the moon. The gravitational pull on Earth is greater than the Moon’s, so you weigh a lot less on the moon. Depending on the time of day, you would see different things. Just like we see the Sun “moving” in the sky on earth, you would see the Earth and the Sun moving while on the Moon.Although the Moon is moving, you wouldn’t be able to tell, just like on
