How Mountains are Made

"How Mountains are Made" by Kathleen Weidner Zoehfeld is a Let's Read-and-Find-Out
Science Stage 2 picture book.

This book is narrated by children who go hiking up a mountain. They go on to explain the different layers of the earth that form the lithosphere.

There are illustrations showing the different plates and how those plates move.

"In other places, pressure deep within the earth pulls and stretches the crust. The stretching sometimes causes long cracks, or fault lines, to cut through the crust. The crust on one side of a crack may slide slowly upward, while the crust on the other side pushes downward. Block-shaped mountains are form this way."

You will also learn how volcanoes are made, how scientists measure a mountain's age and how mountains are changed by weather.
