The Water Cycle: Precipitation, Condensation, and Evaporation

1. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

How Evaporation & Transpiration Contribute to the Hydrologic Cycle

2. How Evaporation & Transpiration Contribute to the Hydrologic Cycle

Evaporation and transpiration are important components of the water cycle, and while they are the same process they arise from different sources. In this video lesson you will learn about these two parts of the cycle and how they contribute to the overall movement of water on Earth.

What is Humidity? - Definition, Measurements & Effects

3. What is Humidity? - Definition, Measurements & Effects

Humidity is an important aspect of the atmosphere because it affects both weather and climate. In this video lesson you will learn about the different types of humidity and understand how temperature affects water vapor in the air.

Measures of Water Vapor Content

4. Measures of Water Vapor Content

When you think of all of the things you measure, water vapor probably doesn't come to mind. This lesson will explore different ways to measure water vapor in the air!

Causes of Saturation & Saturation Processes

5. Causes of Saturation & Saturation Processes

Have you ever wondered what happens to water vapor in the air around you? This lesson will explore saturation, or what happens when the air can't hold anymore water.

What is Cloud Formation? - Definition, Types & Process

6. What is Cloud Formation? - Definition, Types & Process

There are many different types of clouds that form in the sky. In this video lesson you will learn about how clouds form, as well as the different types of clouds and how they are classified.

Adiabatic vs. Diabatic Processes: Cloud Formation

7. Adiabatic vs. Diabatic Processes: Cloud Formation

Why does air cool? And how is this related to cloud formation? This lesson will explore the adiabatic and diabatic processes, which are a couple of ways the air can cool, and then relate this to cloud formation.

Air Lift: Definition & Processes

8. Air Lift: Definition & Processes

In this video lesson, you will learn about air lift. You will also identify the different ways air is lifted, as well as some of the effects each mechanism has.

Types of Atmospheric Lapse Rates

9. Types of Atmospheric Lapse Rates

Have you ever wondered what happens to air as it rises? Well, you've come to the right place. This lesson examines lapse rates, or the speed at which air cools as it rises in the atmosphere.

Types of Condensation

10. Types of Condensation

There is evidence of condensation all around you, even if you don't know it! This lesson will explore the different types of condensation, including dew and fog.

Formation & Dissipation of Cloud Droplets

11. Formation & Dissipation of Cloud Droplets

Have you ever wondered why a cloud forms? Well, you've come to the right place! This lesson will explain why clouds form and will also examine why they disappear.

The Effect of Atmospheric Moisture on Climate Variability

12. The Effect of Atmospheric Moisture on Climate Variability

You might not think water vapor in the air can impact the climate, but it can. This lesson will explore how water vapor and climate are related and will also explain how climate change is impacting the amount of water vapor in the air.

What is Precipitation? - Definition, Types & Formation

13. What is Precipitation? - Definition, Types & Formation

Precipitation comes in many forms, but it all comes from the same general process. In this video lesson you will identify different types of precipitation, as well as how precipitation forms in the atmosphere from condensation.

Causes of Precipitation: Convection, Orographic Uplift & Frontal Uplift

14. Causes of Precipitation: Convection, Orographic Uplift & Frontal Uplift

Discover what precipitation is and learn about what causes it. Understand and visualize how air masses are affected by changes in temperature and topographical features to produce precipitation.

Precipitation Forming Processes

15. Precipitation Forming Processes

In this lesson, you will learn how water molecules turn into precipitation. Also, you will discover how varying conditions can lead to different types of precipitation.

Global Precipitation Distribution's Relation to Wind & Pressure Patterns

16. Global Precipitation Distribution's Relation to Wind & Pressure Patterns

The water cycle of evaporation, condensation, and precipitation isn't the only thing that determines if it will rain or not. In this lesson, we'll look at the effects of wind and pressure patterns on rainfall around the world.
