How Can You Read a Mountain’s History From Its Shape?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How can you read a mountain’s history from its shape?

The Big Idea

You can read a mountain's history from its shape, because every shape is a clue. It is like reading a book written in rock, with no words at all. Let's learn the clues.

Folds and Layers

Step one: look for folded rock layers. Folds show that Earth's crust squeezed the area. They tell us the rock was once flat, and was slowly pushed into waves.

Glacier Clues

Step two: look for glacier clues. U-shaped valleys, bowl-shaped cirques, and long moraines show that glaciers were here. A lone boulder may be an erratic dropped by ice, far from where it began.

Weathering Clues

Step three: look for wear clues. Scree slopes and hoodoos show how frost and rain wear rock away. Each clue is a page in the story, and you can learn to read them.

A Closer Look

Let's take a closer look at the clues! Folds mean the crust squeezed here. Cirques and U-shaped valleys mean glaciers carved here. Scree slopes mean frost broke the rock. And hoodoos mean weather wore away the soft rock.

Quick Facts

Quick facts! Geologists often sketch landscapes to record these clues. A sketch helps them slow down and notice details. Each clue is like a page in a story. Many clues together tell the whole mountain story, from long ago until now.

Think Like a Scientist

Now, think like a scientist! Look at a photo of a mountain. List three clues that it holds about its past. Draw each clue. Then share your story of the mountain, from long ago until today.

Outro

Every mountain tells a story. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
