Ch 58: TExES Core Subjects EC-6: Earth Systems & Cycles

About This Chapter

This chapter presents lessons that were designed to help prepare you for your upcoming Texas Examinations of Educator Standards (TExES) Core Subjects EC-6 test. These lessons are on Earth systems and cycles, such as the hydrosphere, the rock cycle, and the carbon cycle.

TExES Core Subjects EC-6: Earth Systems & Cycles - Chapter Summary

Let our subject-matter experts help you study geological systems and cycles as you get ready to take the TExES Core Subjects EC-6 test. These lessons are intended as a refresher to assist you in answering test questions on topics like:

  • Internal and external forces shaping the surface of our planet
  • Materials that make up the earth
  • Earth's geosphere, hydrosphere, biosphere and atmosphere
  • Precipitation, condensation, and evaporation in the water cycle
  • The rock cycle
  • The cycles of matter
  • How humans their impact the environment

Our expert instructors created these short text and video lessons to get you up to speed on Earth's systems and cycles. Each lesson features a quiz that you can take at the end. If it turns out you need to go back over any of the video lesson material, you can do so by referring to the transcript provided. You can also go right to any specific place in the video using our timeline tool. If you're stuck on a particular concept, feel free to submit a question to one of our expert instructors.

The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

1. 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.

Earth's Materials: Minerals, Rocks, Soil & Water

2. 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.

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

3. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.

The Distribution of Water on Earth

4. The Distribution of Water on Earth

Water covers most of Earth but in a variety of forms. In this video lesson you will learn about how water is distributed on Earth, though you may be surprised to find out just how little of it we can access!

The Water Cycle: Precipitation, Condensation, and Evaporation

5. 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.

Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

6. 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.

Weathering: Definition & Explanation

7. Weathering: Definition & Explanation

Discover how rocks and minerals are broken down by chemical and mechanical forms of weathering. Learn about some of the many geological formations created by weathering, from large caves to beautiful arches made of rock.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

8. 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.

Human Impacts on the Environment

9. Human Impacts on the Environment

The human population continues to grow, but the size of Earth and the resources available for our use are limited. Humans greatly impact the world around them, and our actions can and often do have dramatic and long-lasting consequences.
