Which is true of the electromagnetic radiation, incident on the earth? Select one or more: n a. 100% of sunlight reaches the surface of the earth b. Only visible light is transmitted by the atmosphere O C. All light is blocked by the atmosphere at night (That's why it is dark) O d. All radiation is blocked by the atmosphere n e. Visible light and parts of the UV and IR are transmitted by the atmosphere What is the major function of the outer atmosphere (above -50 km)? (This function is important for life on Earth, and for much of the other chemistry that occurs on Earth.) Select one: O a. To provide electrons for reactions at lower altitudes O b. To break down chemical pollutants O c. To filter out harmful high-energy radiation o d. To act as a greenhouse cover, keeping the Earth warm O e. To transport chemical species from place to place. Why is there an ozone layer instead of just a homogenous mix of ozone distributed throughout the entire atmosphere? Select one or more: n a. Ozone is lighter than air and floats to the top b. The UV radiation needed to make ozone gets mostly absorbed before it can penetrate too deeply into the troposphere O c. People-made pollution destroys most ozone in the lower atmosphere O d.. Ozone has higher bonding energy than oxygen and can survive where oxygen cannot. e. The pressure in the upper atmosphere is too low for efficient three-body collisions
