What are some possible reasons why the rocks are red?
- The rocks are totally composed of red stuff.
- Only the surface of the rocks is red.
- Someone, perhaps, vandals or space aliens, painted the rocks.
Possible ways to test these explanations
- Test A: If only the surface is red, then a simple test
is to break off a piece of the rock and see if the rock is some
other color inside. Unfortunately, we can't actually do that from
- Test B: Fortunately, Nature has already done test A
for us, and pieces that have fallen off the cliffs are red on
Conclusion from Test B: Either the rocks are red all the way through
or else their surfaces turned red after falling.
- Test C: We would use similar logic to evaluate explanation
number 3, that the rocks are painted. If the rocks are red all
the way through, they are not painted only on their surface. Also,
we could go see if it looks like paint or could chip some off
and analyze the chips for chemicals found in paint.
If someone proposed that the aliens used a special kind of paint
that soaked all the way through the rock and that looks just like
rock, we might have more difficulty eliminating this explanation.
Supernatural explanations, such as this, are commonly beyond the
realm of science, because they cannot be disproved. This supernatural
explanation cannot be disproved, but it does not seem very likely!
- Key Data: Geologists have thoroughly studied this place
and have found that when you break off a little piece with a rock
hammer, the rock is red on the inside.
