which of the following is not an example of human-environment interaction?
a.
building wind farms in texas to harness the environment’s energy
b.
antarctic lands not being visited or affected by humans
c.
constructing the hoover dam on the colorado river
d.
building tunnels to construct the transcontinental railroad

The answer is B

Human-Environment interaction is when humans do something to the environment such as building, mining, hunting and more. If the question asks what is NOT an example of human-environment interaction, then it must be B because “Antarctic lands not being visited or affected by humans” is an example of humans not doing anything to the environment. You can also make sure that this is the right answer by using the process of elimination. You know it can’t be A. because of wind farms are being built than it must be done by humans, and they are interacting with the environment, even though they are doing something that helps the environment. It also can’t be C. because the Hoover Dam was built by humans. and lastly, you know it can’t be D because humans built the tunnels for the railroad. So that leaves us with letter B.

I hope this helped you understand it a little better :)

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
