Weathering: Definition, Types, Causes & Rates

1. Weathering: Definition, Types, Causes & Rates

Ever wondered how erosion could create something as dramatic as the Grand Canyon? The simple answer is weathering. This lesson describes the three major types of weathering, their causes, and how weathering rates can change.

Soil & Erosion: Definition, Types, Causes & Prevention

2. Soil & Erosion: Definition, Types, Causes & Prevention

One of the most important things that we can do to ensure the health of our crops and nearby ecosystems is to reduce erosion. This lesson explains the relationship between soil and erosion, as well as ways to stop erosion.

Theory and Evidence of Continental Drift

3. Theory and Evidence of Continental Drift

If you've ever flown to Europe, you know that it's a long flight. However, if the theory of continental drift has anything to say about it, that flight is only going to get longer. That's right - we are drifting away from Europe!

What is Plate Tectonics? - Definition, Theory & Components

4. What is Plate Tectonics? - Definition, Theory & Components

Imagine ice floating in a glass. Would you believe that we are all living on giant pieces of floating rock, just like the ice in that glass? This lesson explains that theory, an idea known as plate tectonics.

Earthquakes and Volcanoes: Evidence of Earth's Inner Layers

5. 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.
