Why earth's surface is not a consistent state?

Because it consists of three different layers of composition.

Explanation:

The Earth's surface does not have a consistent shape because it is not formed by a single layer, but rather three layers of different compositions and organizations, which end up removing the consistent character from the surface and triggering a character that changes frequently.

These three layers are the lithosphere (which is solid), the hydrosphere (which is liquid) and the atmosphere (which is greasy).

answer: stupidity. they should wait till they can get reward money.

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.
