Welcome to Lesson 4!
Lesson 4 deals particularly with Energy and the Environment. As I mentioned before in the unit overview, this lesson is divided into 3 parts. Part A is basically looking at the products that are formed when we burn fossil fuels and the environmental effects of these fossil fuels products.
In part B we are going to look at global effects, global warming. We will also look, in part C, at acid rain, and again, ozone layer destruction up above in the stratosphere. We'll also look at Ozone formation because of the chemicals that we emit -- the pollutants that we emit -- at the ground level and the fact that Ozone is formed at the ground level, where it is not supposed to be. Ozone is supposed to be in the stratosphere, which we are destroying by some of our actions, and where it is not supposed to be, we are forming it. So this lesson basically talks about some of those aspects.
Go through part A, part B, and part C; together there will be one quiz for this lesson. Your job is to complete all parts and do all the practice quizzes or study mate questions -- different activities. And then, actually, part of lesson 5 will also be included for your next exam. Although we call this a unit, it consists of only one lesson, so some of the next lesson will be included in the next exam.
Lesson 4 Objectives
Upon completion of this lesson, you will be able to:
- Demonstrate a familiarity with fossil fuel composition
- Describe basic combustion chemistry
- Explain the quantitative implications of fossil fuel combustion
- State the health and environmental effects of products of combustion
- Describe the effects of primary and secondary pollutants
