About This Chapter
ILTS Environmental Science: Land, Water and Atmospheric Systems - Chapter Summary
The lessons in this chapter provide information on the structure and composition of the Earth's land, water and atmospheric systems and their influence on factors including erosion and weather. You will learn how these systems have changed through time and what impact that had (and is still having) on our planet. These topics that may prepare you for test questions are included in the videos:
- Cycles of matter - nitrogen and carbon cycles
- The atmospheric cycle
- Natural factors that determine climate
- Global warming's atmospheric causes and its effect on climate
- Forces that have shaped the Earth's surface
- Earth's origin and history
- Use of the Earth's resources to support living organisms
- Erosion and deposition
- Landform diagrams showing an area's geologic progression
- Wegener's Theory of Continental Drift and evidence for continental drift
These videos explore the forces that affect our planet and our lives. The lessons are led by experienced instructors who know how to make learning fun and give you the information you'll need to tackle the test questions.
Objectives of the ILTS Environmental Science: Land, Water and Atmospheric Systems Course
Illinois requires passage of the Illinois Licensure Testing System (ILTS) environmental science content area exam for anyone who wants to teach the subject at the secondary school level. The exam contains 125 questions, segmented into six subareas. All questions are multiple-choice. Questions from the topics covered in the Land, Water and Atmospheric Systems chapter are in subarea IV, which deals with the Earth's systems and the universe. Through the self-assessment tests included with each video lesson, you can review what you've learned and familiarize yourself with the exam's format.
1. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle
Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
2. 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.
3. 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.
4. 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.
5. The Dynamic Earth: Internal & External Forces that Shape Earth's Surface
There are many geologic processes that shape the surface of the Earth. Not only do they build and destroy a variety of landscapes, but they also give us clues to the interior of the Earth and the forces that exist there.
6. Effect of Erosion and Deposition on Landforms
Landforms are constantly being broken down and reformed by the processes of weathering, erosion, and deposition. In this lesson, we explore chemical and physical weathering and how the face of the earth gets changed.
7. How a Landform Diagram Describes the Geological Progression of a Landscape
This lesson describes what a landform diagram is. We'll also discuss some basic laws of geology that can help scientists deduce both the order of events that create a landform and the geologic events that occur after a landform's formation.
8. Evidence for the Mechanism of Continental Drift
As scientists began to explore the ocean floor after World War II, they discovered many new clues to help them solve a mystery that had begun decades earlier - how the continents moved about on the surface of the earth.
9. Alfred Wegener's Theory of Continental Drift
People used to think that Earth was static, and that it never changed. Gradually, a body of evidence was gathered that made no sense in this model. Alfred Wegener, Geologic Supersleuth, laid the groundwork for a whole new theory for the large-scale changing nature of the earth.
