Learn Earth Science

What do you want to learn today?



From the troposphere to the exosphere, study the atmosphere. Topics include the ozone layer, magnetosphere, and weather.

Geology Science


Geology is the study and science of Earth’s land forms. This includes how they were created, have changed over time, and how they will evolve.

Life Science


Biology works with time, disease, ecosystems, and why we are here today. It also works on different scales like individual atoms to the entire biosphere.

Earth Science Career


If you are interested in a career in environmental science, there are lots of opportunities available. Find out how diverse the field is.

Outer Space


Space is beyond Earth’s atmosphere. It applies the concepts from physics, biology, and geology to explain our planet’s origin and evolution.

Ocean Science

Water Science

Water is all around us. From oceans to freshwater lakes, this field studies everything from deep ocean water life to the flow of currents.
