Which landform dominates the united states?

I believe the answer is: mostly taken by plains in which is a landmass or broad area that doesn’t contain much elevation and is usually flat.

These plains is often very ideal for people to live since it tend to provide good soil composition for various plants to grow, enough water sources, and provide good ecosystem for various organisms to live. It also provide a level of weather that is not too extreme.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
