The increased temperature in our atmosphere is due to Group of answer choices the trapping of UV radiation from the Sun by greenhouse gases.   the absorption of UV radiation from the Sun, by the Earth, and re-radiation as heat (IR) energy. the absorption of IR radiation from the Sun, by the Earth, and re-radiation as heat (UV) energy. the trapping of IR radiation from the Sun by greenhouse gases.

With the help of chemical equations, explain how ozone absorbs UV light.

How do chemists know that none of the individual Lewis structures of ozone are not accurate depictions of an ozone molecule, and how is this discrepancy addressed?

SO2 is not actually a significant greenhouse gas, while SF6 is. Explain this difference by commenting on their expected behaviour in the atmosphere. (What will happen or not happen to each gas after it is emitted?)

It is often said that water vapour amplifies the Earth’s greenhouse effect. Indicate one way that an increased atmospheric concentration water vapour can increase the greenhouse effect and one way that it can decrease the greenhouse effect.

please answer both questions

The bonds that hold the atoms in a molecule together behave like simple springs. As a result, atmospheric molecules oscillate at frequencies similar to that of infrared radiation, so that these molecules can both absorb and emit infrared radiation (i.e., resonance). Make a simple sketch to illustrate the greenhouse effect by showing:- infrared radiation originating at the Earth’s surface- a carbon dioxide molecule (with springs) in the atmosphere- any radiation absorbed by the molecules being reemitted in a random directionWhy does the presence of the molecule change the Earth’s temperature?

1. What are the three main types of greenhouse gases, what are their respective characterization factors or global warming potential? 2. What is meant by the efficiency of a solar panel (PV) and what are the implications for a solar farm? 3. How is energy extracted from wind and what are the implications for a wind farm? 4. For a wind turbine, what is the impact of the wind speed on the electricity production and how does the design of the wind turbine dictate its efficiency? What control strategies can be used to optimise the performance of wind turbines? How can energy be extracted geothermally. Explain how geothermal energy can be utilised to contribute towards heat demand and what is the role of co-produced water. 5. 6.
