(2) The reflected waves are received by geophones
(3) The data is transmitted to a laboratory truck

Question 5

Types of oil extraction

Answer 5

1.Water flooding - pump watertowash the oil out (it leaves a big chunk still)
2.Thermal Extracton (injection of steam to make the oil hotter and then less viscous so it flows )
3.Chemical Extraction(polymer to break down large oil molecules )

Question 6

Clean Coal

Answer 6

is a term that refers to technologies and
methods aimed at reducing the environmental impact of
coal-fired power plants

capturing and storing carbon dioxide (CO2) emissions,
reducing air pollutants, and increasing the efficiency of
coalbased power generation.

We can continue to use coal as we always did for
a couple hundred more years since we are
putting all the carbon dioxide back into the
ground
