The surface of our planet is constantly changing. Let’s take a look.
This lesson is 2 of 3 about how the earth changes and how Earth's features are formed. Each Related Lesson found in the right-hand sidebar digs deeper into topics such as the earth's crust, layers of the earth, volcanoes, plate tectonics, and geysers. You can complete them individually, or as a set, to explore and understand the changing Earth.
There are internal and external forces that are constantly changing the earth. Internal forces cause changes that happen inside Earth. External forces cause changes that happen outside the earth. In this lesson, you will explore geysers, plate tectonics, and how volcanoes and mountains are formed.
