Formation of the Earth: Theories

1. Formation of the Earth: Theories

In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.

Geological Evidence of Earth's Formation

2. Geological Evidence of Earth's Formation

How did the Earth form? When did it form? And more importantly, how do we know? Learn about the evidence we have for the formation of the Earth. See how many clues you picked up by taking a quiz.

Earth Processes & Geologic History

3. Earth Processes & Geologic History

In this lesson we will learn about Earth's myriad geologic processes and examine how they have changed its surface and materials over the course of geologic history.

The Rock Cycle: Conservation of Mass & Changes

4. The Rock Cycle: Conservation of Mass & Changes

In this lesson, we'll review the rock cycle. Then, we'll get into how the law of conservation of mass in physics applies to the rock cycle. As we do this, we'll also cover the physical and chemical changes occurring in the rock cycle.

Landform: Definition & Types

5. 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.)

Geological Folds: Definition, Causes & Types

6. Geological Folds: Definition, Causes & Types

Under the right conditions and over millions of years, rock can be deformed so that it is folded into a different shape. In this video lesson, you will identify different types of folds as well as what causes them to occur in rock.

How The Earth is Shaped: Earthquakes, Faults & Tsunamis

7. How The Earth is Shaped: Earthquakes, Faults & Tsunamis

If you thought that the best way to describe the Earth's surface was round, think again! As this lesson shows, the world is much more like a soccer ball than you might imagine.

Effect of Erosion and Deposition on Landforms

8. 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.

How Major Catastrophic Events Disrupt the Course of Life on Earth

9. How Major Catastrophic Events Disrupt the Course of Life on Earth

Do you know that, smart as we are, we can be destroyed any second? History provides us with many catastrophic events that led to mass destruction and this lesson covers a couple.

Human Impacts on the Environment

10. 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.

Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

11. Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

In this lesson you will learn about two ways humans contribute to species extinction. We break up habitats by building roads and clearing land, and we pollute both land and water. You will also learn about the specific terms used to describe the processes, habitat fragmentation and anthropogenic pollution.
