1. Consider the following scenario and answer each question below. There are 2 balloons, each has 1 mole of gas in it and the balloon is 1 meter off the ground. The air is at standard pressure and temperature at this elevation. Red balloon: 46% Oxygen (O2); 54% Nitrogen gas (N2) Blue balloon: 100% Hydrogen gas (H2)

a. calculate the density of gas in each balloon

b. explain what will happen to each balloon (rise or fall); identify which one will rise furthest (use part a in your answer)

c. what factors will determine how high each balloon will rise or fall?

2. Sketch/illustrate out the Haldley/Ferrel cell from range 60 degrees latitudes (N to S) as a cross section of the Earth. Explain the general motion at the surface and at higher latitudes. Define convergence and divergence and show where this occurs in your figure. Explain the effect of the tropopause on the vertical and horizontal movement.
