Question

state two chief characteristics of the revolution of the earth?

Answer 1

.The earth moves round the sun at an average speed of 29.8 kilometres per second
.When the earth is closer to the sun the gravitational pull makes the earth move faster than when it is away from the sun.The speed of revolution is not uniform.

Answer 2

The two chief characteristics of the revolution of the earth are as follows:-

•The earth moves around the sun in an elliptical orbit at an average speed of 29.8 kilometres per second.

•When the earth is closer to the Sun the gravitational pull makes the earth move faster than when it is away from the sun.Thus,the speed of revolution is not uniform.
