Air at the equator is warm and has a ______density, which creates ________ in comparison to the air at the poles.
almond37 [142]

Answer:

Lower, low pressure

Explanation:

The temperature at equator are mostly higher than at the poles almost all times of year. This high temperature causes air at the equator to warm up quickly and thus, the air density reduces and it becomes lighter. Now, light air rises upwards. Thus, creating a low pressure region at equators. This low pressure causes the air near the poles gush towards the equator.

Hence, the blanks will be filled with the words

Lower, low pressure.
