Where is pangaea

In the early s, Alfred Wegener proposed the idea of Continental Drift. His ideas centered around continents moving across the face of the Earth. The idea was not quite correct - compared to the plate tectonics theory of today - but his thinking was on the proper track. In addition, a variant spelling of Pangaea is " Pangea ". It appears in some textbooks and glossaries; however, Pangaea is the current preferred spelling.

Careful studies by scientists showed that rocks had diverse origins. Some rock layers, containing clearly identifiable fossil remains of fish and other forms of aquatic animal and plant life, originally The Great Ice Age, a recent chapter in the Earth's history, was a period of recurring widespread glaciations.

During the Pleistocene Epoch of the geologic time scale, which began about a million or more years ago, mountain glaciers formed on all continents, the icecaps of Antarctica and Greenland were more extensive and thicker than today, and This vast span of time, called geologic time by earth scientists and believed by some to reach back to the birth of the Solar System, is difficult if not impossible to comprehend in the familiar time units of months and years, or even centuries.

How then do scientists The Tertiary is a system of rocks, above the Cretaceous and below the Quaternary, that defines the Tertiary Period of geologic time.

During the million years of dinosaur existence this supercontinent slowly broke apart. Its pieces then spread across the When did dinosaurs become extinct? Dinosaurs went extinct about 65 million years ago at the end of the Cretaceous Period , after living on Earth for about million years. If all of Earth time from the very beginning of the dinosaurs to today were compressed into days one calendar year , the dinosaurs appeared January 1 and became extinct the third week of September.

Did people and dinosaurs live at the same time? After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals including shrew-sized primates were alive at the time of the dinosaurs. Many scientists who study dinosaurs vertebrate paleontologists now think that birds are direct descendants of one line of carnivorous dinosaurs, and Did all the dinosaurs live together, and at the same time? Dinosaur communities were separated by both time and geography.

Different dinosaur species lived during each of these three periods. For example, the Jurassic dinosaur Stegosaurus had already been extinct What is declination? At most places on the Earth's surface, the compass doesn't point exactly toward geographic north. The deviation of the compass from true north is an angle called "declination" or "magnetic declination". It is a quantity that has been a nuisance to navigators for centuries, especially since it varies with both geographic location and time.

Do any mass extinctions correlate with magnetic reversals? There is no evidence of a correlation between mass extinctions and magnetic pole reversals. Are there geologic maps or publications for where I live? Hey there Jasmine, Elijah, and Amelia! The Earth's continents are moving - very s l o w l y - but they are moving closer to one another.

Scientists study the patterns of the continents and recognize those shifts. It's fascinating! Do you have your geology hats on today? We're going back in time to Wonder about the world before we were around! Earth is a super cool place, and the continents shift and move as time goes on.

Can you imagine living on a supercontinent? Great work, Mattisen, Joshua, and Rebecca! We are undergoing some spring clearing site maintenance and need to temporarily disable the commenting feature.

Wonder What's Next? Try It Out Can you believe that supercontinents used to exist? Grab a friend or family member and have fun exploring one or more of the following activities: What continent do you live on? Do some independent Internet research to learn more about your home continent. How many countries does it hold? What are they? How many people live there? What range of climates can be found there? What are its highest and lowest points?

Have fun learning more about the place you call home! Back when Earth was the home of Pangaea, it was also home to something else super. What was it? A super ocean, of course! Think about what it would've been like to build a ship and set sail across an ocean even larger than those that exist today. Do you think you would've wanted to have been an ocean explorer back then?

Why or why not? Can you imagine traveling all the way across a super ocean only to reach the other side of the continent you left from? Do you think you would've had any idea you were just on the other side of the same continent? Have fun thinking about what exploring would've been like way back when!

Ready to have some fun with geography? It can be fun to imagine what life might have been like millions and millions of years ago when there might have been one humongous land mass called Pangaea. Of course, it might not have been called Pangaea by the creatures that lived on the supercontinent long ago. What do you think they might have called it?

While you're at it, can you think of some new names for the current continents? That's right! We want you to rename the continents. Pretend that you're putting together an interstellar brochure for Earth.

You hope to lure beings from other planets and galaxies to visit Earth. But you think that the names of the continents just aren't snappy and descriptive enough. Consider each continent individually. What is special about it? What one word might sum up each continent?

Use those thoughts to help you brainstorm new, snappy, brochure-worthy names for the continents. Have fun and be as imaginative as you want! Did you get it? Test your knowledge.

It's amazing to think that long ago we were all connected.

It's also incredible that the oceans divided us not just geographically, but they divided our culture too. If we all were still connected, would we all be the same? Feb 21, It's funny because Alfred Wegener actually died on an expedition to prove his theory, but nobody found his body it was frozen in ice and later his work was finally accepted, it's really sad to think he wasn't alive to experience his work.

Feb 19, That's some great insight! Thanks so much for stopping by and sharing your thoughts. Beez Kneez Feb 19, Amazing article. It is helping me out in my science class.

Thanks guys! We're glad we could help you out! Cole Feb 19, This article is awesome and we are learning about this in science so this article helped me out a little bit.

We're glad we could help you learn more, Cole! Mariah Feb 7, Elaine Jan 24, We are learning this in science class an it is so cool that all the contents use to all be conected into one super mega content!!!

Jan 26, That's a great way to put it, Elaine! Hi, I'm a collie : Dec 29, Wait a second Jan 3, Isaveth the Fox Mage Apr 3, Apr 4, Isn't it? When you look at a globe, can you see how the continents would come together? Oct 18, What part did you find confusing, alexis? Gloria Oct 15, I love this so much now i know more about this type of stuff. Gloria Oct 12, Oct 15, Awesome, Gloria! We're so glad that you found this Wonder really interesting! Jan 29, That's cool pun intended!!

Braxton Jan 24, Lucas Esten Jan 24, Thanks, Lucas! We're glad you enjoyed learning more about Pangaea! Gabe Jan 24, Thanks, Gabe! We think that you're awesome, too!! I love this artical but what time did this take. Hi, braxton! Pangaea was a super-continent million years ago!!! Ryan Nov 29, Hi i'm Ryan your awesome i love your wonders thx :. Dec 4, Hi, Ryan!! We think you're awesome, too! The second major phase in the break-up of Pangaea began in the Early Cretaceous — Ma , when the minor supercontinent of Gondwana separated into multiple continents Africa, South America, India, Antarctica, and Australia.
