Imaginary line or Half of the earth dividing north east west or south.
I would choose D as they both have weather greatly effected by mountain ranges although A my seem like the answer some southern regions of the Midwest are very hot.
Clearcutting has several negative impacts on both human and environment.
Many studies showed that clearcutting method will cause nearly three times the amount of erosion due to higher risk of landslides.
This will potentially very dangerous for human and the environment around Canada
hope this helps
A cliff collapse could affect the environment by exposing new rock (previously covered by the cliff) to the elements, which could result in runoff of a different nature when it rains. Additionally, the cliff would collapse upon whatever life/features existed at the base of the cliff. One of the most drastic effects could be the shaking of the earth. Cliff failures can result in earthquakes or, if the cliff collapses into a large body of water, massive tsunamis which radically impact coastal environments.
