Short speech on the topic Earth​

Answer 1

Answer:

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.
