About This Chapter
Weather, Climate & Geologic Systems - Chapter Summary
Let us aid in your review of weather and climate, including what determines the climate in a particular region. Our instructors discuss the atmospheric cycle and list a few causes of global warming. You'll learn more about the materials the Earth is made of, study natural resources, and examine the water cycle. After watching these lessons, you should have an understanding of topics such as:
- Differences between weather and climate
- The systems approach to geology
- Minerals, rocks, soil, and water
- Types of landforms
- Renewable and non-renewable resources
- Precipitation, evaporation, and condensation
- Natural factors that determine climate
- How global warming affects climate
Our instructors make learning fun with lively lessons that you can view from a computer or mobile device anytime you have a few minutes to devote to study. A short quiz follows each video, letting you assess your learning and see where you need extra study. You can print out a sheet of quiz questions to use for offline study as well. A written lesson transcript lets you read along with the narrator.
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.
2. Understanding the Systems Approach to Geology
Most geological events are influenced by many different factors. Instead of just looking at one factor, the systems approach to geology emphasizes a more holistic approach to understanding the world around us.
3. Earth's Materials: Minerals, Rocks, Soil & Water
Although the earth is a very complex system, there are only four main components of Earth that are the building blocks of life. These components are referred to as Earth's materials and include minerals, rocks, soil and water.
4. How Earth Materials Sustain Animal and Plant Life
The earth can be a very complex system with many different interacting parts. But, at its base, it is made up of four main materials that make life on Earth possible for both plants and animals.
5. Other Earth Materials: Metals and Precious Rocks
Our planet contains a variety of natural resources that we rely on to survive. Some of these resources, including metals and precious rocks, are less common than others and serve unique functions.
6. Landform: Definition & Types
Read about landforms and their major features. Learn the differences between formations like mountains and hills, valleys and canyons. (Hint: It has to do with their form.)
7. Earth's 4 Major Geological Subsystems
When we think of the Earth, we mainly think of the physical land we stand on. The Earth system is much more complex and is comprised of four major geological subsystems that interact to carry out many natural processes.
8. What Are Natural Resources? - Definition & Types
Natural resources are materials provided by the Earth that humans can use to make more complex (human-made) products. In this lesson, you will learn some examples of natural resources and how to classify them.
9. How Natural Events Change Habitats
Natural events, like earthquakes, volcanic eruptions, landslides and floods, can be very powerful and destructive. In this lesson, we will see firsthand how they can change human and wildlife habitats in both damaging and helpful ways.
10. Renewable & Non-Renewable Resources: Definition & Differences
We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.
11. 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.
12. 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.
13. Natural Factors That Determine a Region's Climate
Climate is influenced by factors like atmosphere, ocean currents, landforms and plate tectonics. This lesson explains how these effects affect our weather patterns, which determine climate.
14. 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.
