What is the Middle Jurassic?
Q: What is the Middle Jurassic?
A: The Middle Jurassic is the second epoch in the Jurassic period that began 174.1 million years ago and ended at 163.5 million years ago.
Q: What happened in the Middle Jurassic?
A: In the Middle Jurassic, Pangaea began to split apart, separating into Laurasia and Gondwana, and the Atlantic Ocean formed. Tectonic activities closed the Paleo-Tethys Ocean, and a subduction zone on the coast of western North America created the ancestral Rocky Mountains.
Q: When did the Middle Jurassic end?
A: The Middle Jurassic ended 163.5 million years ago.
Q: What is Pangaea?
A: Pangaea was a supercontinent that existed during the Paleozoic and Mesozoic eras that included all the continents of today.
Q: What is Laurasia?
A: Laurasia was a supercontinent that formed in the Late Triassic and included modern-day North America, Europe, and Asia.
Q: What is Gondwana?
A: Gondwana was a supercontinent that formed in the Late Neoproterozoic and included modern-day South America, Africa, Antarctica, Australia, and the Indian subcontinent.
Q: What geological events led to the formation of the Atlantic Ocean?
A: The separation of Pangaea into Laurasia and Gondwana and tectonic activities that closed the Paleo-Tethys Ocean led to the formation of the Atlantic Ocean.
