| Definition
of a Core Sample:
A core sample is
a piece of rock, soil, or ice that is carved, or cut, from the
ground using a piece of equipment that works a lot like an apple-corer.
If you have ever scooped the core out of an apple you would get
an idea of how a core sample is cut. The reason scientists cut
core samples is to get a piece from the interior, or underlying,
layers of rock/ice/soil and look at the parts they couldn't otherwise
see. By studying core samples scientists can get clues about events
that happened in the past at the time the rock/soil/ice was being
formed.
