a) A nearby volcano is tall.
b) A nearby volcano is inactive
c) A nearby volcano is about to erupt.
d) A nearby volcano had once been active.

a) Sandstone
b) Basalt
c) Marble
d) Granite

Why are fossils rarely found in metamorphic or igneous rock?
a) Chemicals toxic to living organisms are released during formation of these rocks
b) Heat and pressure are great enough to destroy the structure of fossils found in these rocks.
c) Decay of radioactive isotopes changes the fossils into a different rock structure
d) Intense magnetic fields found where these rocks form keep organisms from living there

b) The plant absorbs all the water from the soil leaving the rocks dry and brittle.
c) The plant wraps itself around the rock and forces it to crumble.
d) The acidity of the plant forms new types of smaller rocks.
