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 manufacturing and the use of new technologies, such as steam power and electricity. [Read More]

Soil’s Role in Carbon Sequestration The map, “Earth’s Biomes,” shows the locations of 18 types of biomes and their distribution around the world. Compare the map to the Soil Orders on the front of the Geologic Map Day Poster and the Carbon Sequestration Map on the back of the 2022 Geologic Map Day poster.

What trends do you notice about the biomes that match up with soils capable of carbon sequestration? [Read More]
