The Structure of the Atmosphere

1. The Structure of the Atmosphere

If you've ever climbed a mountain or been to the beach, you know that the atmosphere is different at different levels. This lesson explains how the structure of the atmosphere is really like a layer cake.

The General Circulation of the Atmosphere

2. 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.

Temperature, Clouds, Wind & Humidity on the Atmospheric Cycle

3. Temperature, Clouds, Wind & Humidity on the Atmospheric Cycle

Weather is the current state of the atmosphere and is determined by factors like temperature, pressure and humidity. These factors that cause periodic changes in the Earth's air masses are explored in this lesson.

Weather Variables: Air Pressure, Temperature & Density

4. Weather Variables: Air Pressure, Temperature & Density

Weather is influenced by a number of factors. In this lesson, you will learn about three key variables that control weather and how they work together to do so.

Atmospheric Pressure: Definition & Effects

5. Atmospheric Pressure: Definition & Effects

Atmospheric pressure is around us all of the time. The air you are breathing has weight, and although it doesn't weigh a lot, there is a lot of it around. This lesson will cover atmospheric pressure and its effects.

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.

Types of Air Masses & Their Effect on Weather

7. Types of Air Masses & Their Effect on Weather

Air masses affect weather in a number of different ways. In this lesson, you will learn about the different types of air masses found on Earth and how the movement of air masses creates changes in the weather.

What is an Isobar? - Definition & Examples

8. What is an Isobar? - Definition & Examples

Learn the definition of an isobar, then explore the way in which they are applied on a map and what they show. After completing the lesson, you'll understand why isobars are useful tools for predicting weather.

Understanding Weather Fronts: Types & Their Effect on Weather

9. Understanding Weather Fronts: Types & Their Effect on Weather

In this video lesson you will learn about how air masses with different characteristics create weather fronts. You will also identify the different types of fronts, as well as what type of weather occurs along them.

What is Solar Radiation? - Definition & Effects

10. What is Solar Radiation? - Definition & Effects

The sun plays an important role to us on Earth. It provides many things such as light and warmth. But, what is solar radiation and how does it affect us? In this video lesson, you'll learn about solar radiation, how it allows us to survive, and the influence it has on our global climate.

Solar Energy: Effects on Earth's Temperature

11. Solar Energy: Effects on Earth's Temperature

In this video lesson, learn about solar energy and how it affects temperatures on Earth. You will also learn what causes changes in day length and why some parts of Earth experience seasonal differences throughout the year.

Geography of the Four Seasons

12. Geography of the Four Seasons

This lesson will explain how the earth's axis and rotation affect seasons. In doing this, it will also highlight the concept of the summer and winter solstices, as well as how seasons vary around the globe.

The Relationship Between El Nino & La Nina

13. The Relationship Between El Nino & La Nina

In this video lesson, you will learn about El Niño and La Niña. You will understand the differences between them, as well as some of their effects on both ocean waters and weather patterns on land.
