low tide

Why do craters last for millions of years on the Moon's surface?
The Moon has no water or wind to erode the crater.

What part of a comet exsists when a comet is close to the Sun and far away from the Sun?
dust tail

During what two moon phases do we have the highest tides? WHY?!!!!
During new Moon and full Moon we have the highest tides, because the Sun and Moon's tidal forces work together when they are in line with Earth.

How does Earth rotating on its axis help keep the planet at the proper temperature for life?
The Earth rotates quickly on its axis, causing day and night to quickly follow each other in a short period of time. This is what helps keep temperatures mild enough for life. If Earth rotated more slowly, days would be too long and hot and nights would then be too long and too cold.

Asteroids, meteors, meteoroids, and meteorites are words that describe objects in space or objects from space that hit Earth. Explain what each object is and how they are related.
An astroid is a large rocky small in space up to several hundred kilometers wide; a meteoroid is a small asteroid; a meteor forms when a meteoroid hits the Earth's atmosphere; a meteorite is a piece of meteor that lands on Earth

Why don't more astroids hit Earth?
Most astroids orbit in the astroid belt. The great mass of Jupiter holds most astroids in th area beyond mars by the force of its gravity.

What causes Mars and Saturn to have years of different lengths?
Mars and Saturn have years of different lengths because their revolutions around the Sun take different amounts of time. Mars is close to the Sun, travels faster, and in a small orbit. Saturn moves more slowly and has a longer orbit.

Why is the difference between high and low tide in the open ocean so much less than near the shore?
Tides near the shore are affected by the shape of the shore and the ocean floor near the shore.
