When magma rises towards the surface gas bubbles start to form. Whether or not they can escape as the magma is rising affects how explosive the eruption will be.
Even a small cloud can weigh as much as four tonnes – but gravity, chemistry and temperature keep them floating in the sky.
If the insect wants to stay right in front of your nose, it must fly forwards just a little bit when the car is speeding up. But when the car is at constant speed, it only needs to hover.
Both male and female birds sing to impress other birds, but as well as that, they do it for pleasure!

A wormhole is like a tunnel connecting two places in space. They would be incredibly useful and are great for science-fiction stories.
The problem is we haven’t found any evidence of them existing.
The Big Bang created a cloud of dust and rocks that included a lot of rocks that were made of ice, like giant snowballs. That’s where some of the water came from.
Puppies and kittens are born without teeth, but by around two months of age they have a full set of baby teeth.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
Listen up. Today we’re hearing all about why your ears pop when you go up, up, up and away.
The short answer is that the accent you have depends on the people you grew up with and the history of the place that you live in.
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
Echidnas can survive quite low levels of oxygen.
People used to think that boy lions had big shaggy manes to protect their necks from being bitten or scratched during fights. But scientists soon realised this idea didn’t make much sense.
When crustaceans are cooked, some chemicals in their shells react with heat and change colour.
Out there in space there is no air. If you took your helmet off, all the air you need to breathe would whoosh out.
