Hi, we've got three stories from Curiosity.com to help you get smarter in just a few minutes.

I'm Cody Gough.

And I'm Ashley Hamer.

Today you learn about the science behind a space elevator and how it could make space travel

easier, a method to control your impulses, and the six types of

disgust and what they're for.

Let's satisfy some curiosity.

I actually want to follow up on a story we did last week about black lava and how black

lava moves really moves really fast.

Well we had a question from at psycho mouse on Twitter and the question is heard

this on the podcast it was compared to red or hot lava which moves around six miles per hour.

However, today it was reported that Kilauea has lava moving at 16 miles an hour.

So what makes the Kilauea lava so fast? Great question and Ashley looked into this.

It turns out that there are a bunch of different types of magma. Actually they divide it into three types.

So there's basaltic magma and acidic magma and

rheolytic magma. They're all defined by their chemical composition.

Killawaya volcano has basaltic magma. That has a lower silica content which gives it a lower

viscosity, meaning that it's runnier and it can move faster. If it had more

silica than it would be thicker and it would move more slowly.

That actually affects the shape of the volcano too.

Because the magma is so thin, each time it erupts the lava spreads out,

leaving a broad low mound.
