Mining & Fracking

Carly and Avery

Surface

A type of mining where the soil and rock on top are removed.


Differences: More direct. Sediments are deposited closer to the top.


Strip Mining: Scraping away earth to get to the coal that is near the surface,

Destroys landscapes, forests and wildlife habitats
