Question

how does coal differ from pine trees as a source of energy? coal can be replaced easily, while pine trees are difficult to replace. coal is a nonrenewable resource, while pine trees are a renewable resource. coal is a clean source of energy, while pine trees cause environmental damage. coal is an expensive source of energy, while pine trees are an inexpensive source of energy.

Explanation:

Coal forms over millions of years from buried organic matter, so it cannot be replenished within a human timescale, making it nonrenewable. Pine trees are a biomass resource that can be regrown through planting, so they are renewable. The other options are incorrect: coal is hard to replace, not easy; coal causes significant environmental harm, not clean; and coal is not inherently more expensive than pine tree-based energy sources.

Answer:

Coal is a nonrenewable resource, while pine trees are a renewable resource.
