Drag and drop the appropriate type of coal into each box. (For this practice test, write the appropriate letter in each box.) The type of coal most likely found closest to the surface of the earth: The type of coal that contains the greatest amount of carbon per kilogram: (a) Peat (b) Lignite (c) Bituminous coal (d) Anthracite

Short Answer

Expert verified
The type of coal most likely found closest to the surface of the earth: \( (a) \) Peat The type of coal that contains the greatest amount of carbon per kilogram: \( (d) \) Anthracite

Step by step solution

01

Find the type of coal closest to the surface of the earth

We have to look for the type of coal that is found early in the coal formation process. Since the coal formation process starts with peat, the type of coal most likely found closest to the surface of the earth is (a) Peat.
02

Find the type of coal containing the greatest amount of carbon per kilogram

The coal type with the highest carbon content is the one that is at the end of the coal formation process since carbon content increases over time due to pressure and heat. Anthracite is the final stage of coal formation, so the type of coal that contains the greatest amount of carbon per kilogram is (d) Anthracite. So the correct answers are: The type of coal most likely found closest to the surface of the earth: (a) Peat The type of coal that contains the greatest amount of carbon per kilogram: (d) Anthracite
