*Earth is tilted to produce seasons
Quick fact #1
How fast does the earth travel around the sun?
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).
