Change is evident in all the spheres of the Earth.
Changes are the result of internal and external energy sources and of
energy transfer.
|
As an example in meteorology, different latitudes of the earth
receive different amounts of solar energy, resulting in regional
temperature differences.
|
The transfer of energy is responsible for many of the changes to the
Earth’s surface.
One example is the change from potential energy to kinetic energy
during the impact of an asteroid. Pictured here is the Barringer
Crater in Arizona.

Landslides, earthquakes, tsunamis, floods, slumping, mass movement,
erosion and deposition are the result of the transfer from potential to
kinetic energy.
|
Here, a landslide shows the results of the transfer from potential
to kinetic energy.
|
The physical processes at work today are evident in the past and can
be seen in the fossil record.
Pictured here is an example of cross bedding from Zion National
monument, which shows the movement of sand due to wind forces from
millions of years ago.
