Students will review:
This chapter helps students review the concepts in an energy in the earth system unit of a standard middle school earth science course. Topics covered include:
- Solar energy
- Mechanisms of heat transfer
- Weather vs. climate
- Weather variables
- Effects of air masses on weather
1. The Sun as a Source of Energy for Winds, Currents & the Water Cycle
View this lesson to learn how energy from the sun powers our winds, ocean currents and the water cycle. Learn how the winds, ocean currents and the water cycle react to the energy from the sun.
2. 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.
3. Mechanisms of Heat Transfer: Conduction, Convection & Radiation
There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.
4. 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.
5. 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.
6. 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.
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.
8. 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.
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.
