AQA GCSE Combined Science: Chemistry of the Atmosphere
Explores the composition of the Earth's current atmosphere and theories about its evolution. This deck covers the greenhouse effect, the roles of greenhouse gases like carbon dioxide and methane, and the link between human activities and climate change. It also discusses the concept of a carbon footprint and ways to reduce it, as well as the formation and environmental impact of atmospheric pollutants from combustion, such as carbon monoxide, sulfur dioxide, and oxides of nitrogen.

Welcome to this deck on the Chemistry of the Atmosphere. We'll explore the air around us, looking at what it's made of today, and how scientists believe it has changed over billions of years. We will also cover the greenhouse effect, climate change, and the atmospheric pollutants caused by human activities. Understanding these topics is crucial for your GCSE exams.
Lesson#2
Let's start with the air we breathe today. Earth's atmosphere is a mixture of gases. The vast majority, about eighty percent, is nitrogen. The second most abundant gas, making up about twenty percent, is oxygen, which is essential for life as we know it. The remaining one percent is mostly argon, with small amounts of other gases, including carbon dioxide.
Quiz#3
