Answers
Mars has almost every feature that earth has. Scientists have already discovered hills, craters, and dry riverbeds on (1) the Red Planet. New images now show that some parts of the Martian landscape might also be dotted with (2) caves. If confirmed, these caves could be among the only places on Mars to find evidence of (3) past or present microbial life.
Certain pictures taken by (4) the Mars Odyssey spacecraft showed seven possible entrances to (5) caverns. The entrances are dark, circular structures, measuring between 100 meters and 250 meters across (6). Scientists don’t know how deep the caves are. The data do show, though, that temperatures within the structures are constant and different from (7) temperatures of the surrounding land. That suggests that they are indeed cave openings.
Caves would be an excellent place to search for (8) life on Mars. Such covered spaces would protect living organisms from (9) the sun’s ultraviolet rays and from micrometeorites, which shower down on Mars like a continual rain. Scientists are now scouring the rest of the Red Planet for (10) more cavernous evidence. They hope to find caves containing liquid water, which would be even better candidates for (11) harboring life.
