The Earth’s Interior
Introduction
 For much of our history, we have been ignorant of the inside of the
interior on which we live.
 Only is recent years have we been able to develop an image of the
interior of the earth.
 Today, it is known that the earth’s interior is so hot that it should
be in liquid state.
 However, the pressures of overlaying materials make much of it
behave as though it were solid.
 If the pressures were released, this material would quickly turn into
liquid or gaseous states.
