In the Late Permian, a volcanic region in India called the Deccan Traps formed, pumping large amounts of gases into Earth's atmosphere. These created a greenhouse effect, raising global temperatures. This is known as the End Permian Extinction.
By the Permian-Triassic boundary, 250 million years ago, vast deserts covered the planet. Over 90 percent of all animal species on Earth had died out.

How many years do the majority of geologists believe it took for sedimentary rocks to form?
The majority of geologists believe it takes thousands to millions of years for sedimentary rocks to form. The exact time can vary depending on factors such as the type of sediment, environmental conditions, and geologic processes.
How do geologists believe the great lakes were formed?
Geologists believe the Great Lakes were carved from glaciers that crossed over the area thousands of years ago.
Geologist think Earth's continents began to form?
Geologists believe that Earth's continents began to form around 3 billion years ago through a process called plate tectonics. This process involves the movement and interaction of Earth's lithospheric plates, leading to the gradual assembly of landmasses over millions of years. The shifting and collisions of these plates continue to shape the continents we see today.
What do scientists believe happened after an asteroid struck earth million years ago?
The dinosaurs died.
When did snails evolve?
Scientists believe snails started evolving around 5 million years ago, around the Cambrian period.
What rocks of the sierra Nevadas tell geologists about the geologic history of California?
that it was magma about 210 million and 100 million years ago.
Cockroaches how long on earth?
Scientists believe there have been cockroaches on Earth for at least 280 million years. They have discovered fossils from that long ago.
What was Earths Age According to Geologists?
Earth is estimated to be around 4.5 billion years old, based on radiometric dating of meteorites and rocks from Earth's surface. Geologists have used various dating methods to determine the age of Earth, including studying the decay of radioactive isotopes in rocks and minerals.
How far will the moon be from the earth ten million years from now?
The distance between the Earth and the Moon is increasing at a rate of about 1.5 inches (3.8 cm) per year due to tidal forces. In ten million years, the Moon will be significantly farther from Earth, but the exact distance is difficult to predict due to various factors influencing orbital dynamics.
What people studies changes in the earth that took place millions and billions of years ago?
Geologists
Who was one of the two geologists that proposed that the earth has changed over millions of years?
James Hutton
How many years was earth around without life?
Most geologists date the Earth at 4.54 billion years and the oldest fossils (of stromatolites) date from around 3.8 billion years, so based on that, the Earth was without life for around 740 million years. However, there may well have been earlier life - there aren't that many sites with rocks dating back that far.
