The best method for the correlation of sedimentary rock layers several hundred kilometers apart is by comparing

the

• index fossils in the layers

• layers by walking the outcrop

• thickness of the rock layers

• color of the rock layers

What is the relative age of the igneous rock?

• It is older than the limestone but younger than the

  shale.

• It is younger than the limestone but older than the

  shale.

• It is younger than both the limestone and the

  shale.

• It is older than both the limestone and the shale.

The unaltered remains of fossilized animals include:

• petrified wood

• carbon imprints of fern

• mummified and frozen remains

• cast of a trilobite shell

Examples of trace fossils are:

• drawings on rock made by prehistoric men

• frozen remains of elephant-like mammoths

• footprints of animal tracks

• hallow shape of a snail

Fossilized insects have been found preserved in amber which is hardened:

• tree resin

• flower nectar

• blood

• magma

In petrified wood, the original wood has been slowly replaced by:

• another type of harder wood

• preserving salts

• minerals

• Oxygen
