The Mesozoic period (roughly 180MYA) was a period when much change was happening in the Earth's continental arrangement. The final stage of the break up of the supercontinent Pangaea is generally considered to have taken place in this period. Land and sea were different to how we see them today. Pangaea was on the onset of forming 2 smaller supercontinents called Laurasia and Gondwana. The Atlantic Ocean had not yet formed. The Himalayas were not there. It was a very different picture to what we see today. Have a look at this page for further details concerning the break up of Pangaea. http://en.wikipedia.org/wiki/Pangaea

Which is true of North America during the Mesozoic era?
During the Mesozoic era, North America was divided by a shallow sea called the Western Interior Seaway. Landforms such as the Rocky Mountains began to form during this era due to tectonic activity. Dinosaurs were the dominant land animals during this time period.
During what time period did shallow seas cover much of the land?
Shallow seas covered much of the land during the Mesozoic Era, from around 252 million years ago to 66 million years ago. This era is also known as the "Age of Dinosaurs" and was characterized by warm climates and high sea levels contributing to widespread shallow sea formations.
What was the climate like near the end of the mesozoic era?
The climate before the Mesozoic period/era was a relatively warm climate. The Mesozoic Era was an interval of geological time from about 252 to 66 million years ago and is also called the Age of Reptiles.
What geological events were in mesozoic era?
The geological events in the Mesozoic Era include, but are not limited to...The breaking up of Pangaea.The great meteor that hit earth destroying the dinosaurs
What happened to many land and sea animals at Paleozoic era?
During the Paleozoic era, many land and sea animals experienced significant evolutionary changes and diversification. The era saw the emergence of early fish, amphibians, and reptiles, as well as the development of extensive marine ecosystems. However, it ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history, which wiped out around 90% of marine species and a significant number of terrestrial organisms. This extinction dramatically reshaped the biological landscape and set the stage for the Mesozoic era.
What lived in the mesozoic era?
Dinosaurs, birds, early mammals, and flowering plants lived during the Mesozoic Era, which spanned from about 252 million years ago to 66 million years ago. This era is often referred to as the "Age of Reptiles" due to the dominance of dinosaurs during this time.
How was the tethys sea formed in India?
Tethys sea was formed in the Mesozoic era (current era is Cenozoic) about 50-80 million years ago. It was located in the region where the Indian state of Kashmir lies. It was formed due to collision of the Indian and Eurasian tectonic plates, and subsequent draining of the sea/lake.
In what geologic time period did the tethys sea occur?
The TethysOcean was an ocean that existed between the continents of Gondwana and Laurasia during the Mesozoic era before the opening of the Indian Ocean.
What significant tectonic activity occurred during the Mesozoic?
During the Mesozoic era, significant tectonic activity included the breakup of the supercontinent Pangaea, which led to the formation of the Atlantic Ocean through the process of seafloor spreading. This era also experienced the opening of the Tethys Sea and the formation of the Western Interior Seaway in North America.
The super-continent formed at the end of the Paleozoic era?
That was Pangea (from the Greek for Entire Earth). It was surrounded by Panthallasa (Greek for Entire Sea).
Did Significant plate tectonic changes occurred on Earth during the Mesozoic Era?
Yes, significant plate tectonic changes occurred during the Mesozoic Era, which lasted from about 252 to 66 million years ago. This era saw the breakup of the supercontinent Pangaea into smaller landmasses, leading to the formation of the Atlantic Ocean and the repositioning of continents. These tectonic movements influenced global climate, sea levels, and biodiversity, contributing to the evolution of distinctive ecosystems.
