Short Paragraph for Kids on “Earth”

Here is you short paragraph for Kids on Earth!

The earth is a unique planet. It is a huge ball of about 12750 kilometres across and 40,000 kilometres in circumference. The shape of the earth is spherical and not a perfect sphere; it is flattened at the poles.

In size, it ranks fifth and it is the third nearest planet to the sun. It is the only known planet where life is possible because of the presence of water, moderate tempera­ture and moderately dense atmosphere containing gases useful in supporting life.

When seen from the space it appears blue because of presence of water. It is, therefore, also known as blue planet.

Though it is not exactly known, still it is believed that the earth had originated from the sun. About six thousand million years ago, from a ball of swirling dust, clouds and gases it passed through a molten stage and slowly after a long period of 400 million years it shrank to a compact hot mass. Lightning and thundering helped rain to fall for years which formed the atmosphere and hydrosphere on earth.

The planet earth remained barren and lifeless for four thousand million years. It is during the Proterozoic era that life appeared miraculously in the oceans, and trees started the making of the living world. From such a shadowy beginning emerged a wonderful world of living things on earth. So far no form of life has been discovered on any other planet or satellite.
