How does a volcano make a lake?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a volcano make a lake?

The Big Idea

A volcano can make a lake! It sounds surprising. How does it happen?

Collapse

Step one: Collapse. Crater Lake in Oregon formed about 7,700 years ago when a volcano erupted and its top collapsed. That left a huge bowl called a caldera.

Filling Up

Step two: Filling Up. Rain and snow filled the bowl over hundreds of years. No rivers flow in or out.

Clear and Deep

Step three: Clear and Deep. With no rivers bringing in mud, the water is incredibly clear and deep. It's the deepest lake in the United States, at nearly 2,000 feet.

A Closer Look

Let's take a closer look! Erupted. Collapsed bowl. Filled it. A small cone.

Quick Facts

Quick facts! A small volcanic cone called Wizard Island sticks up inside Crater Lake. About 7,700 years ago. Very clear water. No rivers in or out.

Think Like a Scientist

Now, think like a scientist! Fill a bowl with water. Imagine it's a caldera. Draw a side view of the bowl. Add arrows for rain and snow coming in. Where could water leave?

Outro

Crater Lake formed about 7,700 years ago when a volcano erupted and its top collapsed into a bowl called a caldera. Rain and snow filled it over hundreds of years, and with no rivers, it's incredibly clear and nearly 2,000 feet deep. Science is amazing! Keep wondering and keep exploring!
