The main difference between geography and geology
is that geography is mostly dealing with the physical overall shapes of
the land. Geology is a science that is interested in how the land got
into the shape it did.
Geology is mostly about what the ground is
made up of from a natural perspective. What kind of rocks it contains
and how those rocks or layers of rocks got there.
Geography is
mostly dealing with mapping the extent of landforms, how far rivers are,
how long mountain ranges are, how long the coast line is. This is often
from the perspective of people or culture.
