*Earth's gravity control's the moon

*Earth is tilted to produce seasons

Quick fact #1

The Earth is not actually round in shape; in fact it is geoid .This simply means that the rounded shape has a slight bulge towards the equator.

How fast does the earth travel around the sun?

The Earth's average speed is 29.8 kilomiters per second

Does the Earth have seasons at the North and South poles?

Yes. The difference between seasons at the Earth's poles is more one of light than of temperature. The Sun can be seen in the sky of the regions beyond the Arctic and Antarctic Circles for about 6 months of each year, and to be absent from the sky for the other 6 months. It is always cold at the poles, but it is colder in winter, than in summer.

What is the Earth?

The Earth is a planet. It rotates on its axis, revolves around the Sun and moves with the Sun through space. The Earth gets its warmth and light from the Sun. All around the Earth is atmosphere. We breathe it, and it gives us our weather. The air is always moving. The movements of the air make our winds. Small drops of water in the air form clouds. And as the clouds move about they bring us rain and snow and storms.

How big is the earth ?

The mean radius of Earth is 3,959 miles (6,371 kilometers). However, Earth is not quite a sphere. The planet's rotation causes it to bulge at the equator. Earth's equatorial diameter is 7,926 miles (12,756 kilometers), but from pole to pole, the diameter is 7,900 miles (12,720 km) — a difference of only 40 miles (64 km).

Is earth the only planet who is not named after someone/something ?

Earth is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic.

What planet is Earth's twin ?

Venus is sometimes called Earth's twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.

* the outer core

* the inner core

71 Percent of the Earth's surface is covered with water. Earth is the only planet on which water can exist in liquid form on the surface (though there may be liquid ethane or methane on Titan's surface and liquid water beneath the surface of Europa Liquid water is, of course, essential for life as we know it. The heat capacity of the oceans is also very important in keeping the Earth's temperature relatively stable. Liquid water is also responsible for most of the erosion and weathering of the Earth's continents, a process unique in the solar system today (though it may have occurred on Mars in the past).

water on earth

Water is what gives earths it's appearance from space . Earth appear's to be the only planet with large amounts of liquid water. Pictures from earth show earth as a blue planet because of the water .

Quick fact #2

Earth , the third planet from the sun, is the only body in our solar system known to support life.
