Welcome to another edition of Cool Stuff Ride Home. I'm Reggie Rizzou. He's Marcus Paff.

On today's episode, scientists have a new theory on why Earth's continents rise.

A new method on how the pyramids were built has been proposed.

And on this day in history, we look back at CBS's Our Secret Weapon.

That's coming up on Cool Stuff.

Well, going back to one of my favorite science news sources today.

That would be Tom Howarth and BBC Science Focus.

How and why do quote unquote stable parts of continents gradually rise to form some of Earth's

greatest topographic features like the plateaus of Southern Africa?

It's a question that's puzzled geoscientists for decades.

But now, thanks to a new study published in the journal, Nature, we might have an answer.

A team of researchers led by Professor Thomas Gernan discovered that when tectonic plates break apart,

they trigger powerful waves deep within the earth that can cause continental

surfaces to rise by over a kilometer. That's about three-fifths of a mile, if you're

wondering. This process explains the formation of dramatic landforms, such as escarpments and

plateaus, each of which significantly influence climate and biodiversity.

Per Gernan, quote, scientists have long suspected that steep kilometer-high topographic features

called great escarpments, like the classic example in circling South Africa, are formed when

continents rift and eventually split apart.

But explaining why the inner parts of continents, far from such
