Why Do Volcanoes Temporarily Cool the Planet?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do volcanoes temporarily cool the planet?

The Big Idea

Big volcanic eruptions can cool the planet for a while because they launch tiny particles high into the sky. Those particles reflect some sunlight back to space, like a planetary sunscreen. The cooling lasts a year or two, then fades.

A Huge Eruption

Step one: a giant eruption. A really big volcano blasts ash and gases, including sulfur dioxide, high up into the stratosphere. That's far above the clouds and weather.

Tiny Droplets Form

Step two: tiny droplets form. The sulfur gas combines with water to make microscopic droplets, called aerosols, that spread around the world. They form a thin, hazy veil.

Sunlight Bounces

Step three: the veil reflects sunlight. Some sunlight bounces back to space, so less reaches the surface and Earth cools slightly. After a year or two, the droplets fall out of the sky.

A Closer Look

Let's take a closer look at a volcanic veil! The eruption launches gas high into the sky. The gas turns into a thin haze of droplets. That haze reflects some sunlight back to space. The result is a little cooler Earth for a while.

Quick Facts

Quick facts! In 1991, Mount Pinatubo erupted, and Earth cooled by about half a degree Celsius. In 1816, after a huge eruption in Indonesia, much of North America and Europe had a cold summer. People call it the year without a summer. Volcanoes are dangerous. Never go near one.

Think Like a Scientist

Now, think like a scientist! Let's travel back in time. With a grown-up, read about 1816, the year without a summer. What happened to crops and weather? Why was the cooling temporary? Volcano fun is for books only!

Volcanoes can dim the Sun for a little while. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
