I enjoyed reading this article because it explained how Earths water has come from meteorites and comets, which I had never heard of before. I found it interesting that scientists can figure this by studying minerals in rocks and comparing them to the water on earth. I agree with the author that understanding where earths water came from can help us understand where life on earth began. It also makes you realize how valuable water actually is, and makes you appreciate it more.

I enjoyed reading this article because it helped me understand why we function so well. For instance, when it talked about how we are the right distance from the sun. And then explained what would happen that if we were too close most of our ice would be frozen but if we were closer, we would be at risk for a "scorching surface," like Venice.

I found this article interesting because it explained the different theories to how water could have arrived on Earth. It makes sense that comets could have brought large amounts of water to Earth, but it seems weird to me that asteroids could have brought as much water without significantly damaging Earth's surface. Despite hyperactive comets being quite rare, I still feel like they majorly contributed to the water on Earth.

Something I found interesting about this article is how it says how water got on Earth. I would have never guessed that it would've came from things like comets and such. It is still hard to comprehend but very cool, especially knowing how much we rely on water to live.

I enjoyed reading this article because it made me realize how surprising it is that Earth even has water at all. I found it interesting that the early Earth was too hot for liquid water to stay on the surface, which means our oceans had to arrive later from asteroids or comets.

I enjoyed reading this article because I've always wondered where water came from. It described that it came from both comets and asteroids. It was a very interesting concept to think about and the details provided helped me better understand it.

I learned that most of the water on Earth probably came from asteroids and comets that brought ice to our planet after it formed. I also learned that scientists study the types of hydrogen in water, called isotopes, to figure out where it came from. I enjoyed reading this because it made me realize that something as simple as water has an amazing story that connects Earth to the rest of the solar system. It was interesting to see how science can uncover events that happened billions of years ago and help us understand the world we live in today.

I loved this article because I always wondered how and what water is like how it started/came from and I liked how details it is

I enjoyed reading this article because I often find myself pondering where the water on Earth came from, it's cool to learn that it came from asteroids and comets.
