Explore the distribution of coal in Pennsylvania based on geological features, age, and rank. Learn about the differences between eastern and western PA coal reserves and the factors influencing coal formation. Work through questions to understand the coal-bearing regions in the state.
E N D
Does it surprise you that there are large parts of the state that do not have coal reserves? Why do you suppose this is the case?
Do you think coal in one region of PA is significantly older than the coal in the other regions?
The coal in western PA is about the same age as the coal in eastern PA, but the coal in the east is of a higher rank. How is this possible?
Why might the coal in eastern PA have been subjected to greater burial depth and higher temperature?
Work through the questions on the Coal in PA worksheet DCNR (1999) Coal in PA (2002) DCNR (2000)
Describe the terrain in the coal-bearing areas of eastern Pennsylvania.40 Describe the terrain in the coal-bearing areas of western Pennsylvania. Is the terrain consistent across the state, or does it vary?
What main geologic features are present in the coal-bearing regions of Pennsylvania?
List the proper names of 3 of these features, their locations, and the type of coal found there.
Draw the boundaries of any important geologic features from the physiographic province and relief maps on the coal distribution map. Do you notice any relationships between geologic features and ranks of coal?
How might the formation of the geologic features you identified influence the process of coalification?
