Classes of Martian Rock
Even though the rocks seem to be much the same, scientists can see three basic differences in these rocks. The three classes are:
- bright, redder than the dark rock, but not at red as pink
- pink, perhaps covered with a rusty substance
Different kinds of rock are pointed out in the image to the left. Green arrows show dark rocks, the white arrow shows pink rock. Barnacle Bill
was a dark rock, suggesting that it may be an igneous rock
. Scooby Doo
was a pink rock.
Scientists are trying to figure out where the rocks came from, whether 1.) from the impact of a crater, or 2.) from flowing water.
