Read the following passage carefully and answer the questions given below:
We do not feel the earth’s movement because
we are travelling with it at the same speed. ‘But it does move in two ways.
First of all it spins round on its axis just like a top. The axis is through
the top and bottom of the earth—the north and the south Poles. The earth makes
one complete rotation in twenty four hours. This spinning causes our days and
nights. Day is when our part of the earth’s globe is facing the sun. Night is
when we Spin out of the reach of the Sun’s rays. Astronomers call the whole
twenty four hour period the ‘solar day’, The earth spins towards the east which
makes the sun appear to move in the opposite direction from east to west.
The earth’s second motion is in its orbit
around the sun which is 150 million kilometers away. It takes the earth almost
3651 days to travel once round its orbit. This period we call a year. The other
planets each have a ‘day’ and a ‘year’ but their days and years are different
from the earth’s ; because they are of different sizes and lie at different
distances from the sun.
