Question 1

Four forces acting on air ( and water )

Answer 1

Gravity
pressure gradient
Coriolis
friction

Question 2

Horizontal pressure gradients

Answer 2

Typically small gradients exist across large areas

Question 3

Vertical Pressure gradients

Answer 3

Vertical pressure gradients are greater than the extreme examples of horizontal pressure gradients as pressure always decreases with altitude

Question 4

Coriolis force

Answer 4

Deflects any object float across the earths surface- interrupts the straight-line path

Question 5

Earths rotation

Answer 5

Deflection to the right in the north hemisphere, two left in the south hemisphere
