From the Ted Talk by Jill Heinerth: The mysterious world of underwater caves

Unscramble the Blue Letters

I also work with physicists, and they're interested oftentimes in global climate chnage. They can take rocks within the caves, and they can slcie them and look at the layers within with rocks, much like the rgins of a tree, and they can count back in history and learn about the climate on our planet at very different times. The red that you see in this photograph is actually dust from the Sahara Desert. So it's been pekicd up by wind, blown across the Atlantic oacen. It's rained down in this case on the island of aabco in the Bahamas. It soaks in through the ground and deposits itself in the rckos within these caves. And when we look back in the layers of these rocks, we can find times when the climate was very, very dry on earth, and we can go back many hundreds of toanhdsus of years.

Original Text

I also work with physicists, and they're interested oftentimes in global climate change. They can take rocks within the caves, and they can slice them and look at the layers within with rocks, much like the rings of a tree, and they can count back in history and learn about the climate on our planet at very different times. The red that you see in this photograph is actually dust from the Sahara Desert. So it's been picked up by wind, blown across the Atlantic Ocean. It's rained down in this case on the island of Abaco in the Bahamas. It soaks in through the ground and deposits itself in the rocks within these caves. And when we look back in the layers of these rocks, we can find times when the climate was very, very dry on earth, and we can go back many hundreds of thousands of years.
