About 250-million years ago, long, long after the Earth had formed, all the continents of the time had joined together to form a super-continent called Pangaea. This super-continent broke up about 200-million years ago to form two giant continents, Gondwana and Laurasia.In fact, 250 millions years ago the Earth’s seven continents were all grouped together into a supercontinent called Pangea. Just before the days of the dinosaurs the Earth’s continents were all connected into one huge landmass called Pangaea .He began to toy with the idea that in the late Paleozoic Era (which ended about 252 million years ago) all the present-day continents had formed a single large mass, or supercontinent, which subsequently broke apart. Wegener called this ancient continent Pangaea.

What did the Earth look like long ago?
What did Earth look like 3.2 billion years ago? New evidence suggests the planet was covered by a vast ocean and had no continents at all. Continents appeared later, as plate tectonics thrust enormous, rocky land masses upward to breach the sea surfaces, scientists recently reported.
What was Earth like 240 million years ago?
Some 240 million years ago, the patch of land that would one day become the National Mall was part of an enormous supercontinent known as Pangea. Encompassing nearly all of Earth’s extant land mass, Pangea bore little resemblance to our contemporary planet.
How would you describe the shape of the continents today?
All the continents except Antarctica are wedge-shaped, wider in the north than they are in the south. The continents are the planet’s mainlands. They are distinguished from islands, which are smaller land areas that are completely surrounded by water.
How do you think this continent has changed over time?
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn’t.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

8) are supported by paleogeographic evidence originally from the beginning of the Mesozoic supercontinent (Pangaea) and what was the original-Pacific Ocean.
In what way have the continents changed over time?
Impacted by changing temperatures in the layers of the planet, tectonic plates move over and under one another, causing shifts in the locations of the continents over time. The movement of tectonic plates also causes changes in the ocean floor, and volcanoes often form where one tectonic plate meets another.
What will happen to the continents 250 million years from now?
For now it appears that in 250 million years, the Earth’s continents will be merged again into one giant landmass…just as they were 250 million years before now. From Pangea, to present, to Pangea Ultima!
How did continents form?
In 1912, German scientist Alfred Wegener proposed a theory he called continental drift. According to Wegener’s theory, Earth’s continents once formed a single, giant landmass, which he called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today.
How did the continents separate?
Wegener called the supercontinent Pangaea, meaning “all lands” in Greek, and he said it was bordered by Panthalassa, the universal sea. He claimed the lands separated 250 million years ago by the process of continental drift, which means the continents just slowly fractured and went their separate ways.

In Earth’s Beginning

By 220 million years, the beginning of the Triassic era, ago the supercontinent of Pangea had started to break apart. As a rift opened between what is now northern Africa and western Eurasia the Tethys Sea moved in to fill the gap. The land was now dominated by the dinosaurs and the first mammals had already appeared.
Where are the continents in one million years?
Their assessment showed two possibilities – That the current continents will become one super mass akin to Pangea near the equator called “Aurica” or that with Antarctica staying as it is, other continents would be pushed north of the equator and form a landmass called “Amasia”.
What are some characteristics of a continent?
Although each is unique, all the continents share two basic features: old, geologically stable regions, and younger, somewhat more active regions.
