About This Chapter
ILTS Environmental Science: The Dynamic Nature of Earth - Chapter Summary
The lessons in this chapter will help you understand the natural dynamic forces, events and processes that work to change the Earth. Topics you will examine include plate tectonics, climate change, the water cycle and rock cycles. You will also get a look at the instruments used to study these processes and events. Brief video lessons cover the following topics to help you get ready for the test:
- Plate tectonics and how the change its causes in the Earth's surface
- Causes of plate movement
- Convergent, divergent and transform plate boundaries
- Precipitation, condensation and evaporation of water
- Igneous, sedimentary and metamorphic rock
- Earthquakes and volcanoes
- Seismographs, barometers and satellite systems used in the Earth sciences
Led by expert instructors, these brief video lessons will give you a solid overview of the processes that influence changes in the Earth's makeup. After completing this chapter, you will be ready for the test questions.
Objectives of the ILTS Environmental Science: The Dynamic Nature of Earth Course
Anyone wishing to teach environmental science at the secondary level in Illinois must pass the environmental science content area exam from the Illinois Licensure Testing System (ILTS). This test consists of 125 multiple-choice questions. It is divided into six subareas, and the material contained in the Dynamic Nature of Earth chapter is in subarea IV. By utilizing the self-assessment quizzes found at the end of each video, you can get acquainted with the format of the test and gauge your knowledge of the dynamic forces at work on the Earth.
1. Plate Tectonics: A Unified Theory for Change of the Earth's Surface
After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.
2. Causes of Tectonic Plate Movement
In this lesson, we explore the causes of plate movement, including thermal convection, ridge push and slab pull. Students will learn how these processes complement each other and form a theory for tectonic plate movement.
3. Plate Boundaries: Convergent, Divergent, and Transform Boundaries
In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.
4. 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.
5. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks
In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.
6. Earthquakes and Volcanoes: Evidence of Earth's Inner Layers
The interior layers of the earth are not able to be observed directly, so scientists need to rely on other information to learn about it. S waves, P waves, and magma from volcanoes and earthquakes give a glimpse at the layers of the earth by providing data that can be built into a model of the earth.
