Introducing Earth Science
Video
Earth Systems
• Lithosphere• Hydrosphere• Atmosphere• Biosphere
•Litho- Stone, rock•Hydro- Water •Atmos- Vapor•Bio- Life
Greek Roots
• Create a question that relates to one of the earth systems.
• Develop a hypothesis.• Design an experiment.• Define your independent and dependent
variables.• How will you change your independent
variable?• Describe how you will measure your
dependent variable.• What will be your control.• I will ask you to do a short oral presentation at
the end of class.
• How does the sun’s energy contribute to life on Earth?• What factors affect air density and how to they influence winds, air
masses, fronts and storm systems?• How do human activities impact air quality?• What are the causes of recent changes in atmospheric composition
and how might they affect the climate in the future?
• What impacts have humans had on the atmosphere and air quality?• What are the consequences of climate change?• How does the human population influence the availability of
freshwater? • How do humans influence water quality in NC’s river basins, wetlands
and tidal environments?• How do human activities impact erosional processes and what are
the possible consequences of this?• What makes a resource sustainable?
4 Branches of Earth Science
• Astronomy• Meteorology• Geology• Oceanography
Astronomy
The study of objects beyond Earth’s atmosphere
MeteorologyThe study of forces and processes that cause
the atmosphere to change to produce weather
Geology
The study of the materials that make up Earth and the processes that form and change these materials.
Oceanography
The study of Earth’s oceans. Encompasses the creatures that inhabit the oceans, different mechanical and chemical processes, and human impacts to oceans.
What is name for the type of scientist who studies each of these branches?

• Geologist• Oceanographer• Meteorologist• Biologist
The study of Earth is broad, so scientists have identified four main
Earth Systems…
Lithosphere
• Includes the crust, mantle, and core of earth.• Geologists study the lithosphere.
Hydrosphere• Water found in Earth’s oceans, seas, lakes,
rivers, glaciers, and water in the atmosphere makes up the hydrosphere of the Earth.
• Oceanographers study water• Meteorologists study water in the atmosphere
Atmosphere• Gases that are surrounding our planet.• The atmosphere is necessary for breathing,
protection from harmful radiation, and it helps maintain a normal temperature so that we may live!
• Meteorologists study the atmosphere.
Biosphere• Includes all organisms on Earth as
well as the environments in which they live.
• All scientists studying Earth Science also study the biosphere. Scientists are careful not to harm/damage any environment that any organism is living in.
