How Are Perfectly Rectangular Icebergs Formed?



In October, NASA scientist Jeremy Harbeck spotted two almost perfectly rectangular icebergs that broke off of the Larsen C ice shelf in Antarctica. These tabular icebergs have a flat top and hard corners, indicating that they were recently formed.

How Are Perfectly Rectangular Icebergs Formed?

Following is the transcript of the video:

Narrator: Does this image look Photoshopped, fake, or even created by aliens? You wouldn’t be alone in thinking that. But, you would be wrong. This is actually a naturally occurring phenomenon. What you’re seeing is a tabular iceberg. Tabular icebergs form a plateau, with a flat top. Unlike non-tabular icebergs, which usually have a rounded top. This iceberg was photographed in October, by NASA scientist Jeremy Harbeck. Most icebergs look similar to this at first, although this one is exceptionally rectangular. So how are these perfect icebergs formed? All icebergs form when a piece or sheet of ice breaks away from a large ice shelf or glacier. And because of ice’s innate crystal structure, it tends to break along straight lines.

Dr. Jan Lieser: The icebergs that we usually see are weathered. They get beaten up by winds and waves and they lose bits here and they shed a bit of, shed a piece there. This is a recent carving event.

Narrator: This iceberg broke off of the Larsen C Ice Shelf in Antarctica. Over time, wind, waves, and warmer water will degrade the iceberg and break it apart, eventually turning it into the rounded shape you’re probably more familiar with.

Dr. Jan Lieser: These regular shapes, that won’t stick around for long. If we look for this iceberg today, which is only a couple weeks after it was originally spotted, it won’t look like that anymore at all.

Narrator: As this tabular iceberg floats away and changes shape, it won’t resemble the iconic iceberg in the photo. But it will live on, thanks to social media.

    Watch flat earthers gonna add this as an example to their "Theories" but completely distorted using their science

  2. I CALL Buullshiiiiit !!! Those are disguised (Snow-camo) military bases housing troops that prevent us from discovering the earth is flat!

    (My next comment'll probably be "r/whoosh).

  3. Mr

    WHAT ?!??

    Antarctica Still exists ????

  4. rían

    this didnt help whatsoever tf

  5. Joshua Gloria

    Maybe you can also ask the expert of the "Ancient Aliens" for further explanations?😂😂😂

  6. KMS Tirpitz

    Rectangular icebergs are actually giant chunks of white-chocolate Hershey Bars, hence why they're shaped like that. The iceberg is a Hershey bar. It's not first grade you doo-doo heads!

  7. Cerellix

    so basically "it just broke off like that"

  8. gtsyptr

    Relax, god is just experimanting with the terrain tools

  9. Jeff Beck

    ICEBERGS DO NOT AND CAN NOT EXIST. ICE MELTS QUICKLY IN WATER. DO THE EXPERIMENT YOURSELF. SEARCH AARON DOVER "ICEBERGS ARE A HOAX"

  10. Marcus Wong

    It is not a perfect cuboid with rectangular surface

  11. A7C

    Idk if nasa actually have twitter

  12. Salah Kefah

    americans have AliEn sPeCiAliStS and wow there logic😂😂

  13. Eman M

    Sees one kind of rectangle looking ice sheet makes an entire video showing one random sheet

  14. Daniel 031118

    is it me or the doctor sounds like Arnold schwarzenegger lol

  15. bg70

    I'll name it "Wow iceberg!!"

  16. ExtraOx

    So…

    You didn't even explain why its rectangular

  17. Battery🔋10%

    Narrator said :"created by aliens"

    Me: lol. N ow, thats explains how they're made 😂👌

  18. Cronibet

    So does global warming make square shapes? Lmao

  19. InCrIpTiOn

    "We simply drop a giant ice cube into the ocean every now and then"

  20. Clueless

    It's probably because you flew very fast over it with your elytra

  21. Daniel Tan

    Chill guys. It's just one of Cell's failed arenas.

  22. Pineapple Pizza

    So, according to the comments the iceberg was either made by aliens or Thanos.
