**6)** Convection is not involved in B. of other gases like methane and ozone.
 * 7)** Kelvin.
 * 8)** No, the air is also made up of nitrogen and a small amount of argon and carbon dioxide. There are also traces
 * 9)** A: Stratosphere B: Thermosphere
 * 10)** They are slowing down and moving around less.
 * 11)** No, temperature is the measure of AVERAGE KINETIC energy, while thermal energy is the measure of TOTAL KINETIC energy.
 * 12)** The molecules move farther apart and collide less, resulting in less atmospheric pressure and less density.
 * 13)** The dense high pressure moves towards low pressure areas creating winds.
 * 14)**
 * < **High pressure systems** ||< **Low pressure systems** ||
 * < Happens over a cool region ||< Happens over a warm region ||
 * < The air mass cools, and becomes denser, resulting in the high pressure air sinking ||< The air mass warms and becomes less dense, resulting in the low pressure air rising ||
 * < Wind moves clockwise around high pessure centre ||< Wind moves counterclockwise around low pressure centre ||
 * < Usually results in clear skies ||< Usually results in wet weather ||
 * 15. ** The Coriolis Effect deflects winds to the right in the northern hemisphere and to the left in the southern hemisphere. 

**16. ** The albedo depends on the direction and the distribution of incoming radiation. Therefore, in areas where there is less solar radiation, there is less albedo that is reflected. <span style="color: black; font-family: "Arial","sans-serif"; font-size: 10.0pt; line-height: 115%; mso-fareast-font-family: "Times New Roman";">
