The Earth was formed about 4.7 billion years ago. The Earth’s shape is very close to that of a sphere, not perfectly spherical. The Earth’s equatorial diameter is about 12,756 km, which is slightly larger than the polar diameter; about 12,714 km Surface Area of the Earth is 510,065,600 km2 of which 148,939,100 km2 (29.2 %) is land and 361,126,400 km2 (70.8 %) is water.

The Earth rotates on its axis, an imaginary straight line through its centre. The two points where the axis of rotation intersects the Earth’s surface are called as the poles, one of them is called the North Pole and the other is known as the South Pole. One rotation with respect to Sun is completed in 24 hours, called a solar day.

The Earth rotates in counter-clock direction or from left to right-or eastward direction. Rotation serves three reasons. First, the axis of rotation serves as a reference in setting up the geographic grid of latitude and longitude. Second, it provided a good measure of the passage of time, 24 hours or 1440 minutes or 86,400 seconds a day. Third, it greatly influenced the physical and life processes on Earth.
he Earth is not only a planet where we live in, but is the most important natural resource. The territory in possession of a nation is important from its economic interest viewpoint. One of the ten largest countries in the world in terms of territory, six belong to emerging market economies.

Earth is the planet we live on. It is the third planet from the sun. It is the only planet known to have life on it. The Earth formed around 4.5 billion years ago.(5) It is one of four rocky planets on the inside of the solar system. The other three are Mercury, venus and Mars.

The large mass of the Sun makes the Earth move around it, just as the mass of the Earth makes the Moon move around it. The Earth also turns round in space, so different parts face the Sun at different times. The Earth goes around the sun once (one "year") for every 365¼ times it turns all the way around (one "day").

The Moon goes around the Earth about every 27⅓ days. As the Earth goes round the Sun at the same time, the changing light of the Moon takes about 29½ days to go from dark to bright to dark again. That is where the idea of "month" came from. However, now most months have 30 or 31 days so they fit into one year.

The Earth is the only planet in our Solar System that has a large amount of liquidwater.(6) About 71 persent of the surface of the Earth is covered by oceans. Because of this, it is sometimes called the "Blue Planet".
