Why Do Giant Sandstorms Roll Across Deserts?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do giant sandstorms roll across deserts?

The Big Idea

Giant sandstorms happen when strong winds blow across loose, dry ground! The wind lifts sand and dust high into the air. Sometimes the dust forms a huge rolling wall that looks like a mountain moving across the land.

Loose, Dry Ground

Step one: loose, dry ground. In a desert there is often little rain and few plants to hold the soil down. That makes sand and dust easy for the wind to lift.

Strong Winds

Step two: strong winds. When the wind blows hard, it scoops sand and dust into the air. Heavy sand stays low, while light dust rises high.

A Rolling Wall

Step three: a rolling wall. Sometimes a storm collapses and sends a cold wall of wind rushing across the ground. It picks up dust into a giant cloud, which can be a mile high.

A Closer Look

Let's take a closer look! First, the wind blows hard. Second, it lifts loose sand and dust. Third, a giant cloud rolls across the land. When a storm comes, people head inside. Staying safe is smart.

Quick Facts

Quick facts! Big dust walls in the Sahara are called haboobs, from an Arabic word. A dust wall can be a mile high. It can travel at the speed of a fast car. In a real storm, people go inside and cover their faces.

Think Like a Scientist

Now, think like a scientist! Stay indoors and picture a sandstorm. List three things you would do to stay safe. Tell a grown-up your list. Great planning!
