Question

Polar satellites are used for high-resolution imaging of the earth’s surface because _____

(a) they have better cameras

(b) they are very high above the surface of the earth and travel slowly to gather more information

(c) they are closer to the surface of the earth and can cover vast areas very quickly

(d) they can be launched by most countries in the world

This question was addressed to me in an online quiz.

Enquiry is from Gravitation in portion Gravitation of Physics – Class 11

Answer 1

The correct choice is (c) they are closer to the surface of the earth and can cover vast areas very quickly

To explain: Since polar satellites orbit close to the surface of the earth, it is easier to click images of the planet’s surface with greater detail. Their high orbital velocity enables them to view most of the surface strip-by-stip very quickly with which high-resolution images can be constructed.
