We find carbon everywhere on Earth ─ in trees, rocks, fossil fuels, oceans, and even you! Carbon doesn’t stay in one place, through. Scientists study how carbon moves from one place to another. This is the carbon cycle. The Industrial Revolution, starting in the 1700s, saw a move to large-scale...

Convection is the density-driven movement of a fluid material. Often, convection is driven by either heating from below or cooling from above the fluid. When a liquid is heated, it expands slightly, which makes it less dense. The fluid with lower density rises up, in the same way that a party...

Atmospheric scientists study weather processes, the global dynamics of climate, solar radiation and its effects, and the role of atmospheric chemistry in ozone depletion, climate change, and pollution. They observe what's going on in our atmosphere today and compare it to records from years past. To...

Hurricanes are among the most common and most destructive types of natural hazards on Earth. Because they occur across space and time, hurricanes can be better understood using maps, particularly digital maps within a Geographic Information Systems (GIS) environment. GIS allows you to use maps as...
