Volcanism, but not as we know it #MarsRock

A new rock in Algeria sheds light on the history of our little brother, Mars.

As announced on

“An unusual meteorite found in Algeria in 2012 has given scientists information about volcanic activity on Mars, and it’s not like anything we’ve ever seen on Earth. Analysis of the 6.9-ounce meteorite by an international team of scientists, has helped determine that sometime in its 4.5 billion-year history, Mars had a single volcano that erupted continuously for more than 2 billion years.”

Earth has plate tectonics, which constantly shuffle the Earths surface, like pieces of jigsaw being moved around a table. This regenerates the surface of the Earth every few thousand years of so, and so Earth volcanoes can’t get much older than that. But on Mars there is very little tectonics, and probably none at all. So a volcano can just keep going and going. The mystery of the Mars rock, solved by old volcanism

  1. It is very interesting that mars had a volcano that erupted for about 2 billion years. I never knew that a volcano could erupt for that long of a time period. So now that scientists have studied the rock we now can understand what kind of rocks and stuff we are dealing with before we send people.

  2. I never knew Mars had active volcanoes. The fact that one still remains is insane to me. It’s crazy that it is the size of Arizona. I’m from Arizona and it’s a pretty big state. The crust doesn’t move on Mars and that is interesting to me. Thats a main reason the volcano is so huge. It is so cool to learn information like this.

  3. This is really I interesting because we know that the plate tectonics cause shifts on earths like volcanoes and earthquakes. Because mars doesn’t really have plate tectonics, their volcanoes are always continuously growing.

  4. How could a Volcano erupt continually for 2 billion years? Just wrapping my mind around the idea of 2 billion years is difficult. Makes a lifetime seem smaller than a grain of flour. The enormous scale of our solar system is fascinating.

  5. I find it amazing how a meteorite that small of only 6.9 ounces could hold so much information for scientists to uncover. The fact that we are able to gather information about Mars without ever stepping foot on Mars. Especially the fact that there’s evidence of volcanoes on Mars is mind blowing. I never knew that there was that much information being found on Earth. I’m excited to find out more.

  6. It is very neat how we can collect all this knowledge we have about Earth. We compare to other planets, who know that we slowly have plate tectonics. Another thing that was interesting was that the shadows of the volcano can cover that much space.

  7. It’s amazing to think that a single volcano has been erupting for more than 2 billion years. Even the size of it is pretty unimaginable. Mars is such an interesting planet and the fact that it’s so close to us makes it possible to discover so much more about it.

  8. They said that Mars used to have numerous volcanoes. What happened to them? I dug further into another video and it explained it was caused by sputtering. A new term I had never heard of.

  9. It’s just amazing that planets are all created or orginated roughly at the same time but yet have such differences. It’s odd to think both of the terrestrial planets (earth and mars) have a different makeup. One has tectonics and the other does not. Planets are strange to think about because we just assume they are the same in one way or another. It’s amazing what we can learn from just a meteorite, such a small fragment of a planet and space.

  10. How amazing is that we still continue to find many more astonishing facts about these planets!!! And it really is using out “earth based knowledge” Being able to experiment and compare the two is very valuable to human history!

  11. A volcano the size of Arizona, that erupted for over 2 billion years is amazing! Learning about Mars is so interesting because its so close to us, but it is also very different. It’s interesting to think about how plate tectonics have stopped Earth from having these huge volcanoes that erupt for 2 billion years, I’ve never been thankful for plate tectonics until now!

  12. Its weird when you think about the creation of the planets. All of them originated from the same place and yet they are all so different. Yeah Earth and Mars are terrestrial planets but the fact that Mars lack of tectonics is fascinating. A single volcano versus a lot of scattered volcanoes here. Also we found this out through a meteorite. That’s just amazing.
