Which landform is a large nearly flat area that rises sharply above the land around it

 PLATEAU

A plateau is a broad flat area of land that rises above the surrounding land. The word stems from the French language, from a word root meaning "flat."  The largest and highest plateau in the world is the Tibetan Plateau, which is about 3 miles above sea level, and extends over 600 miles north/south and about 1600 miles east/west.  Around the Tibetan Plateau are large mountain ranges that include the world's tallest peak, Mount Everest.

Sidenote:  I lived for many years in West Texas, in the region known as the Llano Estacado, or "Staked Plains."  It is an expansive plateau or mesa region with an elevation between 3000 and 5000 feet.

explanation:

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.
