|How is it beneficial to humans if scientists find
out more about the layers of the earth?|
The Earth supplies us with the materials and
energy needed for our lives. Knowing as much as we
can about the earth ---what it is like today and
how it has evolved through geologic time, going
back 4,500,000,000 years, that is 4.5 Billion
years, is crucial to understanding how humans
can build a sustainable life.
Geology (and so the study of layers of Earth)
is useful in:
-predicting earthquakes, volcanic eruptions,
landslides, and other natural disasters (and the
damage they cause)
-finding mineral resources (oil, iron, titanium)
-finding out how the environment has changed in
the past (climate, sea level)
-finding out what living things existed at
different times in the past, and how they survived
or did not survive the changes in the environment
that I mentioned.
