Why is the middle of a hurricane sometimes so clear and calm?

Why Does Earth Have Deserts? For the same reason it has Rainforests: Hadley Cells!!!

Public bathrooms are teeming with microbes! You know to wash your hands, but when choosing between a hand dryer or a paper towel to dry them off— what’s your cleanest bet? Hosted by: Hank Green

Even if a volcano is just a few miles away, you might not hear it erupt. How is that possible? It has to do with a phenomenon known as sound shadows! Hank will tell you all about it in this new episode of SciShow! Join us!

So... what makes the wind? You might be surprised to learn that it has to do with two of Earth's spheres; The Hydrosphere and the Geosphere. In this episode of Crash Course Kids, Sabrina takes us to the beach to chat about how the wind...

There’s a moment after you close your freezer door that it becomes slightly harder to open again. It might pass quickly, but it’s not just in your head.

Usually when it's snowing outside, it's really calm, pretty, and fun to play in! But there are certain types of big snowstorms, called blizzards, that can get really windy, wild, and even dangerous!

Why is my weather app sometimes wrong? Well it has a lot to do with wind. Jet Streams, air cells, the shape and movement of the Earth... there are a lot of things that make weather a little unpredictable. In this episode of Crash Course...

Hot Air Balloons! They're those big, beautiful balloons people can float up to the sky in-- but how do they get up there?!

Have you ever seen a weather report on TV and wondered how they can tell when it's going to rain days before it happens? Well, there are special scientists called meteorologists who use all kinds of cool equipment to predict the weather!

Today we’re going to talk about two types of cyclones: mid-latitude cyclones and tropical cyclones. Mid-latitude cyclones are huge weather systems that bring day-to-day weather in the mid-latitudes. They're the reason the weather is...

What are air currents? Air currents are like rivers of wind caused by areas of high and low pressure.The air above the land is warmer and less dense, so it rises. The air over the water is cooler and heavier. The cool air rushes in...

Some parts of the world get way more extreme storms than Jessi and Squeaks are used to. They're called hurricanes!

Pupil outcome: I can explain the weather associated with a depression. Key learning points: - Depressions are areas of low pressure where air is rising. - Warm air and cold air meet at depressions causing changeable temperatures and...

An igloo is made of compressed snow. Compact hardened snow is a great insulator of heat because snow is nothing but semi-frozen water with roughly 95% trapped air. The air molecules trapped between the tiny ice crystals create air...

Beacon of Maracaibo (also called Maracaibo lightning/Catatumbo lightning) refers to the phenomenon of relentless lightning which goes on for nearly 300 days in a calendar year and for over 9 hours in each of those days. This seemingly...

What causes different kinds of weather? What is wind and where does it come from? How can pressure systems help us predict the weather? Earth Science - Weather - Learning Points. Understanding weather systems is the key to reliable...

What makes a tornado nature's most dangerous storm? Scientists are working to identify the unique set of circumstances which combine to create a tornado. Earth Science - Weather - Learning Points. Tornadoes are a violent, spinning vortex...

The weather systems on our planet are all driven by one thing: air. Discover how our weather is driven by energy from the Sun, affecting the movement of air. Earth Science - Weather - Learning Points. Our weather is a chaotic and complex...

What is the Coriolis effect? How is it produced and how does it affect our weather? Earth Science - Weather - Learning Points. The way wind blows determines thunderstorms to hurricanes. The Coriolis Effect is a deflection of moving mass...

Hurricanes are renowned for their destructive power and the devastation they leave behind. But how do they form and where? Earth Science - Weather - Learning Points. Hurricanes are tropical storms with constant wind speeds. Hurricanes...
