§Which best explains how the Coriolis Effect influences weather conditions?
a)It causes winds to rotate, forming tornadoes on Earth.
b)It causes winds to move to the right in the southern hemisphere.

Explain why water can form on grass in the early morning when the air is clear.
The air near the ground cools and allows for water vapor to condense to form droplets of water.

C.There is more oxygen for jet engines to use at high altitudes.
D.It takes more fuel to climb to higher altitudes.
B. The lower pressure outside the plane allows it to fly faster.
