Earth's Interior

These are yellowish-green pieces of rock from the ancient Greek words which mean foreign and rock.

The following ideas show the types of evidence used by geologists to study and learn the unseen interior of the Earth EXCEPT.

• direct evidence from plants and animals

• direct evidence from rock samples

• indirect evidence from seismic waves

• none of the above

______________ brings up many samples or rock and gives geologists many clues.
