In this chapter, you can watch videos that explore important concepts related to the hydrosphere to improve your chances of success on the ORELA Middle Grades General Science assessment. In no time, you will be prepared to:

  • Discuss the distribution of water on earth and the properties of ocean water
  • Analyze the patterns of ocean circulation and its effect on climate
  • Define rivers and explore how rivers and streams affect Earth's surface
  • Share the meaning of groundwater and explain the relationship between ground and surface water
  • Explain the water cycle and hydrologic cycle
  • Describe how evaporation and transpiration contribute to the hydrologic cycle
  • Understand the meaning and process of runoff and infiltration

This chapter can help you get the understanding of the hydrosphere you need to answer related questions on the assessment. Watch the short lessons, access full video transcripts and ask our experts questions about any lesson topic.

The Hydrosphere - ORELA Middle Grades General Science Chapter Objectives

The ORELA Middle Grades General Science assessment is designed to gauge the science comprehension of educators in Oregon who are interested in acquiring licensure to teach the subject in middle grades. The computer-based test consists of 150 multiple-choice questions. Passing requires a minimum score of 228.

The assessment is broken into four content domains that test your knowledge of the nature of science, physical science, life science and earth and space science. Topics in this chapter are found in the earth and space science domain, which constitutes approximately 25% of the entire test. Prepare for questions in this section by reviewing the lessons then taking self-assessment quizzes and a chapter exam. Questions on the quizzes and exam are similar in format and content to those found on the test.

The Distribution of Water on Earth

1. 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!

Properties of Ocean Water

2. Properties of Ocean Water

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.

Ocean Circulation: Patterns & Effect on Climate

3. Ocean Circulation: Patterns & Effect on Climate

The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.

Rivers: Definition & Explanation

4. Rivers: Definition & Explanation

Explore rivers and how they develop from small streams to swiftly flowing rapids. Learn about how rivers shape the land around them, creating canyons, flood plains and deltas.

How Rivers and Streams Affect the Earth's Surface

5. How Rivers and Streams Affect the Earth's Surface

Rivers and streams are powerful, ever-changing systems that can alter the surface of the Earth. While they share many similar features, they can be vastly different. In this lesson, we will learn how rivers and streams form, transport sediment, and flood.

What is Groundwater? - Definition & Explanation

6. What is Groundwater? - Definition & Explanation

Groundwater accounts for up to 20% of all the fresh water on Earth. This lesson will explain what ground water is and its important aspects. Once you've finished the lesson, test your understanding with a quiz.

Ground and Surface Water: Effects On Landscapes

7. Ground and Surface Water: Effects On Landscapes

In this lesson, you will learn how groundwater and surface water form features on Earth and cause changes in landscapes. You will also learn about the different types of features formed by each type of water.

The Water Cycle: Precipitation, Condensation, and Evaporation

8. 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.

The Hydrologic Cycle: Definition, Process & Diagram

9. The Hydrologic Cycle: Definition, Process & Diagram

The hydrologic, or water, cycle describes the storage and movement of all water on Earth. This lesson will cover the different reservoirs where water can be stored and how it moves between them.

How Evaporation & Transpiration Contribute to the Hydrologic Cycle

10. How Evaporation & Transpiration Contribute to the Hydrologic Cycle

Evaporation and transpiration are important components of the water cycle, and while they are the same process they arise from different sources. In this video lesson you will learn about these two parts of the cycle and how they contribute to the overall movement of water on Earth.

Runoff & Infiltration: Definition & Process

11. Runoff & Infiltration: Definition & Process

When water falls to the ground as precipitation, it can either fill the spaces in the soil below ground or run across the surface. In this video lesson, you will learn about the processes of infiltration and runoff, and how they are an important part of the water cycle on Earth.
