Question

PLEASE NURRY ITS TIMED!!!

Study the arrow that is circled in the image.



What happens at this point?

Warm air is rising.
Cool air is sinking.
There is a difference in air pressure.
Cool air is less dense than warm air.

Not part of that one ^^

Where are the strongest jet streams located?

over high altitudes
over land
in the lower atmosphere
far away from the equator

Answer 1

Cool air is less dense than warm air

Over high altitude

Answer 2

1. Option C, There is a difference in air pressure

2. Over High altitude

Step-by-step explanation:

1. The air pressure for cold air is higher than that of warm air. It is so because the cold air is denser than that of warm air and thus has higher number of air molecules with in a given area . The cold air being denser sinks while the warm air being lighter rises. Also the wind moves from cold areas towards the warm area.

Hence option C is correct

2. Jet streams are caused in regions which have high variations of difference between the temperature at different point of time. At high altitudes in polar region, the temperature during days is high while the temperature during night is extremely low and hence polar jet streams are caused

Thus, option A is correct
