Oil drilling, though difficult, is pretty simple when compared to oil shale extraction. Getting oil shale, solidified oil trapped inside rock, to the surface is currently more expensive and environmentally harmful than conventional drilling. How much do you know about this potential fuel source trapped beneath the Earth's crust?
After oil shale is excavated, extreme heat liquefies the trapped fuel and separates it from rock in a process called:

0.5 tons (0.4 metric tons)
1.5 tons (1.36 metric tons)
3 tons (2.7 metric tons)
