Geoscientists study life
Earth is the only planet in our solar system with lots of liquid
water. Because Earth is wet, it also has life. For billions of years,
Earth systems have interacted to produce and continually change the
variety of plants, animals, and other forms of life. Remember the
dinosaurs? After living on Earth for almost 200,000,000 years they
became extinct because an asteroid hit Earth around 65,000,000 years
ago. However, plants and animals also interact harmoniously with Earth
systems. An example is the way many marine animals such as clams extract
calcium carbonate, dissolved in the ocean, to build their shells.
Some geoscientists
examine the interactions between life and the other components of
the Earth system (rocks, water, air, space). Others study the chemical
reactions between life and these systems. In search of evidence, they
wade through wetlands, dive in submersibles to deep ocean vents, drill
into soil and rocks, and launch balloons into the atmosphere. They
work to help protect our environment and our health as they track
pollutants that can go through soil, water, and air. What do we call
these geoscientists? Biogeoscientists or Biogeochemists
Some geoscientists explore the development of life in extreme environments,
such as the boiling pools near geysers, and the permafrost of the
Arctic. Then they apply what they learn to the growing knowledge about
the environments of other planets. Is there extraterrestrial life
within our solar system or beyond? You could be part of a team that
discovers some answers to this very big question. What do we call
these geoscientists? Astrobiologists
Some
geoscientists examine fossil records to understand past climate
changes and then apply this knowledge to current or possible future
climate changes. They are on the cutting edge of science, so stay
tuned for the startling new knowledge about the interaction of life,
Earth, and space that they will discover! What do we call these
geoscientists? Paleobiologists
