Answer

The gravitational pull of the moon on the ocean

Answer

High pressure systems stalling over mountain ranges

Question 15

How does the Coriolis effect behave at the Earth's equator?

Answer

It is at its absolute maximum strength

Answer

It pulls air directly into space

Answer

It causes water to drain counter-clockwise in sinks

Question 16

If you are operating near an airport, what is the primary risk you must mitigate?
