Why Are Some Mountain Cliffs Red, Green, or Yellow?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why are some mountain cliffs red, green, or yellow?

The Big Idea

Mountain cliffs can be red, green, or yellow because of the minerals inside the rock. Different minerals make different colors. Layers of rock can show up as colorful stripes.

Iron Makes Red

Step one: iron makes red and orange. Iron in rock rusts, just like an old nail, and turns red or orange. The red cliffs in Waterton Lakes National Park get their color from iron.

Other Minerals

Step two: other minerals add colors. Copper minerals can be green or blue, and sulfur can be yellow. Limestone and quartz are often pale gray or white.

Stripes and Lichens

Step three: layers make stripes. Each layer of rock can have different minerals, so the cliff looks striped. Lichens add orange, yellow, and green on top, and Rainbow Mountain in Peru shows striking stripes.

A Closer Look

Let's take a closer look at rock colors! Iron rusts into red and orange. Copper minerals can turn green or blue. Sulfur can be yellow. Limestone and quartz are pale gray or white.

Quick Facts

Quick facts! The red rock cliffs in Waterton Lakes National Park get their color from iron. Rainbow Mountain in Peru has bright natural stripes. Lichens are living things that add color on top. Look with your eyes, and leave the rocks where they are.

Think Like a Scientist

Now, think like a scientist! Find a few colored rocks from the ground with a grown-up. Rub them on a wet paper towel to see if they leave streaks. Compare the streaks with a rusty nail. Which color is the strongest?
