Describe how the meteorite collision at the end of the Mesozoic affected the atmosphere and the biosphere?
The meteorite collision at the end of the Mesozoic era caused significant changes in the atmosphere by releasing immense amounts of debris and gases that led to global cooling and darkening of the skies, disrupting photosynthesis and causing mass extinctions. The biosphere was greatly impacted as the sudden environmental changes wiped out around 75% of all species, including dinosaurs, and allowed for the rise of new species and ecosystems in the following Cenozoic era.
How did the meteorite collision at the end of the Mesozoic affect the atmosphere and the biosphere?
The meteorite collision at the end of the Mesozoic era caused widespread fires, tsunamis, and dust that blocked sunlight, leading to a cooling of the atmosphere. This period, known as the Cretaceous-Paleogene extinction event, resulted in the mass extinction of many species, including the dinosaurs, and paved the way for the rise of mammals and other new life forms in the aftermath.
What was the composition in the atmosphere during the Mesozoic age?
During the Mesozoic era, which lasted from about 252 to 66 million years ago, the atmosphere was characterized by higher levels of carbon dioxide, approximately 1000 to 2000 ppm (parts per million) compared to current levels of around 400 ppm. Oxygen levels were also higher, ranging from 26% to 30% compared to the current 21%.
What is the other name for the mesozoic era?
The Mesozoic Era is also known as the Age of Reptiles.
The Cretaceous period was a part of what era?
It was part of the Mesozoic Era.

What contributed to the extinction that marks the end of the Mesozoic era?
meteorite collision
was a meteorite responsible for the extinctions in the mesozoic era?
paleontologists think but nobody knows its just a theory
Where is the crater that is evidence of the meteorite impact that ended the Mesozoic?
The Chicxulub impact crater in the Gulf of Mexico is the most likely suspect for the meteorite impact that caused the Mesozoic extinction. The crater is 180 km in diameter, suggesting that the impacting body was approximately 10 km in diameter.
Was there oxygen in the Mesozoic Era?
Yes, the atmosphere was more than adequately oxygenated for life in the Mesozoic.
Which event marks the end of mesozoic era?
The end of the Mesozoic Era is marked by the mass extinction event that wiped out the dinosaurs, known as the Cretaceous–Paleogene extinction event. This event was likely caused by a combination of factors, including a meteorite impact and volcanic activity, and led to significant changes in Earth's ecosystems.
What likely contributed to the extinction that marks the end of the Mesozoic Era?
The likely contributors to the extinction event marking the end of the Mesozoic Era, known as the Cretaceous-Paleogene (K-Pg) extinction event, include a large asteroid impact on Earth, massive volcanic activity, and climate change. The asteroid impact at Chicxulub in present-day Mexico is considered a primary factor, causing widespread devastation and leading to the decline of many species, including the dinosaurs.
When did mesozoic area begin?
http://en.wikipedia.org/wiki/Mesozoic Btw, it's not the Mesozoic "area" but the Mesozoic era. Hope this was helfpul!
What is the period of the mesozoic era?
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
What era began and ended with mass extinctions?
Paleozoic - climate change Mesozoic - meteor
