97
Q

What organ is responsible for horizontal accelerations?

A

Otoliths

98
Q

How does the ITCZ affect wx?

A

ITCZ shifts due to earth’s tilt and rotation and it’s relation to the sun. As the ITCZ line moves, it brings with it rain from the ocean, thus monsoon season.

Q

What is the tropopause?

A

The boundary between the troposphere (temp decreases with height) and stratosphere (temp increases with height).

103
Q

Is the height of the tropopause everywhere the same?

A

No because it depends on the ISA which is affected by the temperature.
