Show Notes
The ground beneath your feet feels completely still... but the continents are actually moving all the time. In this episode of Why Though?, Dr Matt Agnew explains why continents drift across the Earth, how tectonic plates slowly carry them around the planet, and how that movement creates mountains, deep ocean trenches and earthquakes.
What you'll discover: Continents move just a few centimetres each year... about as fast as your fingernails grow Long ago, every continent was joined together in one giant supercontinent called Pangaea Earth's crust is made of enormous tectonic plates rather than one solid shell When plates collide they can push up mountain ranges like the Himalayas When one plate slides underneath another, it creates deep ocean trenches through a process called subduction Earthquakes happen when pressure builds between stuck plates before suddenly being released

It looks like magic. It makes spooky fog that pours down instead of floating up. And it never leaves a puddle. So what is dry ice actually doing?
A cheetah? A race car? A rocket? All great guesses. All completely wrong. The fastest thing on Earth is something you can't hold in your hand... and understanding it means understanding lightyears, the speed of light, and why space distances break normal numbers.
Have you ever walked outside on a bright sunny day and suddenly sneezed... with no dust, no pepper, no cat fluff anywhere? Just sunshine and a sneeze? There's a real science reason behind it.
Here's something nobody tells you. Most of a fart has absolutely no smell. So what's actually making everyone pinch their nose?
Lightning and thunder happen at exactly the same time. So why does the flash always arrive before the boom?
