Answer : 3. "They are closer to the surface of the earth and can cover vast areas very quickly"
Explanation :
Explanation: 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.
