Weather vs. Climate: Definition, Differences & Effects

1. Weather vs. Climate: Definition, Differences & Effects

This video lesson will guide you in understanding the difference between climate and weather. Discover how they are different but related and how they are the ways you can describe atmospheric conditions on Earth.

Types of Air Masses & Their Effect on Weather

2. 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.

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

3. 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.

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.

The General Circulation of the Atmosphere

5. 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.

Understanding Weather Fronts: Types & Their Effect on Weather

6. 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 Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale

7. What Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale

Tornadoes are dangerous storms that affect millions of people. In this video lesson, you will learn how and where they form, as well as how scientists classify tornadoes using the Enhanced Fujita Scale.

What Are Thunderstorms? - Definition, Types & Formation

8. What Are Thunderstorms? - Definition, Types & Formation

Thunderstorms are common all over the world. In this video lesson, you will learn what they are, how they form and how they create thunder and lightning.

What Are Cyclones? - Types, Causes & Effects

9. What Are Cyclones? - Types, Causes & Effects

The word cyclone refers to many different types of storms. In this video lesson you will learn about how cyclones form, what makes each type different, and what their effects are on both people and the environment.

Hurricanes: Types, Formation, Causes & Effects

10. Hurricanes: Types, Formation, Causes & Effects

Hurricanes are dangerous storms that affect millions of people each year. But what are hurricanes and how do they form? In this video lesson you'll learn about where and how hurricanes develop as well as the types of hurricanes that are possible.

The Relationship Between El Nino & La Nina

11. 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.

What Are Floods? - Causes, Types & Prevention

12. What Are Floods? - Causes, Types & Prevention

In this video lesson, you will study floods, their causes and their effects. You will learn to identify various methods that are used to prevent floods and explore how preventing natural flood cycles can lead to dangerous flood events.

What is the Hydrosphere? - Definition & Examples

13. What is the Hydrosphere? - Definition & Examples

Have you ever wondered how much water is on Earth? In this lesson, we will trace how water travels around Earth. You will learn the definition of a hydrosphere and take a quiz to test your knowledge.

The Effects of Coastal Erosion on Shoreline Features

14. The Effects of Coastal Erosion on Shoreline Features

Shorelines constantly change due to the pounding of waves that erode coastal structures. Learn about shoreline features that are formed through coastal erosion, such as wave-cut cliffs, wave-cut platforms, sea arches and sea stacks.

Global Climate Change: Effects and Mitigation Strategies

15. Global Climate Change: Effects and Mitigation Strategies

In this video lesson, you will learn about the potential effects of global climate change. You will also learn how some are working to better understand climate change in order to slow the rate of temperature increase on Earth.
