Question

There is only one natural satellite - the Moon. But there are many man-made or artificial satellites revolving around the Earth. Aryabhatta, IRS-IB and INSAT-2A are some Indian artificial satellites. They are more than 300 Km away from the earth. At this height, the Earth’s gravity and atmosphere do not affect them. Artificial satellites are of many kinds. Of them weather satellites send information and pictures of clouds, storms and ocean currents. They are used to predict the weather. This information is also used to warn people about storms, floods, forest fires etc. Communication satellites are used to transmit telephone conversation and TV programmes across the earth. They are helpful in sending messages through fax machines, using mobile phones and the internet. Science satellites send information about outer space. Astronomers study this data and get to know more about things in space. These satellites are launched into space by rockets. Once beyond the earth’s gravity and atmosphere, they are sent circling around the earth by the force of another rocket. There is nothing in space to obstruct the path or speed of those satellites. So they continue to keep going around the earth, just like the moon.
Find words/phrases from the passage which mean the same as the following : (1x4) i. force of attraction between an object and the earth ii. body of water or air in motion iii. block up/put something in the way of iv. to send forth as a self-propelled vehicle​
