A long long time ago, maybe about 1,000,000 years ago, the mantel which is under the earth's crust (and we're standing on the earth's crust) was just like the earth's crust. But now it is hot melted rock. Over the years the mantel gets hotter. The Mantel gets so hot that it melts through the continents and separates them even more. Answer Plate Tectonics. The earths crust is floating on the molten magma which is what the centre of the Earth is made of. There are currents in the magma which tore the original single land mass (Pangea) apart and dragged the pieces apart. The pieces, called plates, are still drifting. Sometimes they crash into each other like India and Asia.
What else can I help you with?
What would happen if particular continents broke up?
If particular continents broke up, it would lead to significant geological, environmental, and ecological changes. Tectonic activity would increase, potentially resulting in earthquakes and volcanic eruptions. The separation could also alter ocean currents and weather patterns, impacting climates and ecosystems. Additionally, the fragmentation could affect biodiversity, as species would become isolated and evolve independently.
Pangaea broke up into what two continents?
Pangaea broke into Gondwanaland and Laurasia.
Which fossil occurs on the most landmasses and what does this suggest about when these particular continents broke up?
The fossil that occurs on the most landmasses is the Glossopteris, a seed fern found in South America, Africa, Antarctica, India, and Australia. Its widespread distribution suggests that these continents were once part of a single supercontinent, Gondwana, which existed during the late Paleozoic era. The presence of Glossopteris on multiple continents indicates that they were connected until relatively recently in geological history, supporting the theory of continental drift and suggesting that these landmasses began to separate during the Mesozoic era.
What was the super-continent in the continental drift hypothesis called?
Pangaea or Pangea was the super-continent in the continental drift hypothesis.
What do you call the crust making up the continents?
The crust that makes up the continents, or land masses on Earth is called continental crust. The crust that makes up the oceans is called oceanic crust.
Which fossil occurs on the landmasses what does this suggest about when these particular continents broke up?
This isn't the full answer sorry but The globetrotters plant
What fossils occur on the most landmasses when does this suggest about when these particular continents broke up?
This isn't the full answer sorry but The globetrotters plant
What does this suggest about when these particular continets broke up?
This suggests that these continents broke up around 200 million years ago during the Mesozoic era. This breakup eventually led to the formation of the Atlantic Ocean.
What does glossoptetsis suggest about when these particular continents broke up?
Glossopteris was a plant whose fossils have been found across South America, Africa, India, Antarctica, and Australia, suggesting that these continents were once connected as part of the supercontinent Gondwana. This supports the idea that these continents broke up around 180 million years ago during the Jurassic Period.

What does the glossoptersis plant suggest about when these particular continents broke up?
The presence of Glossopteris fossils in present-day southern continents such as South America, Africa, India, Antarctica, and Australia suggests that these landmasses were once joined together in a supercontinent known as Gondwana. The breakup of Gondwana began around 180 million years ago during the Jurassic period.
What was the name of the continent that then broke up into 7 continents?
Pangea
What were the two continents called when Pangaea broke into two?
The two continents that formed when Pangaea broke apart are Laurasia in the north and Gondwana in the south. These two supercontinents eventually broke up further to form the continents we have today.

Additionally, the fragmentation could affect biodiversity, as species would become isolated and evolve independently.
Which fossil occurs on the most land masses what this suggest about when these particular continents broke up?
The trilobite fossil is found on all continents, suggesting they were once connected in a supercontinent called Pangaea about 300 million years ago. The distribution of trilobite fossils across land masses helps support the theory of continental drift, which states that continents were once joined together before drifting apart due to tectonic plate movements.
What was the name of the supercontinent before all of the continents broke up?
Panpeia
