4. Global Warming: Atmospheric Causes and Effect on Climate

Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.

Greenhouse Gases and the Enhanced Greenhouse Effect

5. Greenhouse Gases and the Enhanced Greenhouse Effect

In this video lesson, you will learn about the five main greenhouse gases and how their unnaturally high concentrations are leading to the enhanced greenhouse effect and global climate change on Earth.

Factors That Affect Wind: Pressure Gradient Forces, Coriolis Effect & Friction

6. Factors That Affect Wind: Pressure Gradient Forces, Coriolis Effect & Friction

In this video lesson, you will learn about wind and some factors that affect it, such as air temperature and pressure, the Coriolis effect, and friction. By the end of this lesson, you will also understand how Earth's rotation plays a role in how winds travel.

The General Circulation of the Atmosphere

7. The General Circulation of the Atmosphere

The Sahara Desert, tropical rainforests, and cold polar winds are all due to Earth's rotation. In this video lesson, you will learn how this rotation has created global air circulation patterns on Earth and how it is responsible for such diverse climate patterns across the globe.

What Is Air Pollution? - Definition, Sources & Types

8. What Is Air Pollution? - Definition, Sources & Types

In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.
