There will be a mass extinction in the cenozoic era?
There is no concrete evidence to suggest a mass extinction will occur in the Cenozoic era. Extinctions have happened throughout Earth's history, but predicting a mass event in a specific era is challenging. It is crucial to focus on conservation efforts to prevent any potential threats to biodiversity.
When geologists refer to the big five' what are the referring to?
When geologist refer to the Big Five they are referring to the five mass extinctions on Earth. Some of these extinctions are the Paleozoic and Mesozoic eras.
What are the causes of planet destruction?
1. local star goes nova and obliterates planet with cast off stuff 2. planet falls into a star or black hole 3. impact from another object such as a large enough meteor, comet or other planet
Why many scientists believe that something other than asteroids have caused most of the catastrophic extinctions of the Earth's past?
Many scientists believe that something other than asteroids have caused most catastrophic extinctions because some events, like the Permian extinction, show multiple stressors occurred simultaneously. The Deccan Traps volcanic eruptions coincide with the extinction of dinosaurs, suggesting a connection. Additionally, gradual environmental changes and feedback loops could have contributed to mass extinctions more than singular events like asteroid impacts.
What do fossils teach us about extinction?
The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.
Name some birds that survived mass extinctions.?
If they went extinct they wouldn't survive
When geologist refer to the big five what are they referring to?
When geologist refer to the Big Five they are referring to the five mass extinctions on Earth. Some of these extinctions are the Paleozoic and Mesozoic eras.
What are mass extinctions followed by?
Mass extinctions are usually followed by long periods of low or absent population. Some species always survive a mass extinction, following the Darwinian law of survival. When the dinosaurs died out the mammals began to prevail and eventually took over.
The causes of some of the earliest extinctions such as the Permian extinction are because humans started changing the earth?
A+ False
When geologists refer to the Big Five what are they referring to?
When geologist refer to the Big Five they are referring to the five mass extinctions on Earth. Some of these extinctions are the Paleozoic and Mesozoic eras.
How many mass extinctions have occurred in the 500 million years?
In the last 500 million years, there have been five major mass extinctions, often referred to as the "Big Five." These include the Late Ordovician, Late Devonian, Permian-Triassic, Late Triassic, and Cretaceous-Paleogene extinctions. Each event resulted in the significant loss of biodiversity and had profound impacts on Earth's ecosystems. Additionally, some scientists suggest that we may be in the midst of a sixth mass extinction driven by human activities.
There will be a mass extinction in the cenozoic era?
There is no concrete evidence to suggest a mass extinction will occur in the Cenozoic era. Extinctions have happened throughout Earth's history, but predicting a mass event in a specific era is challenging. It is crucial to focus on conservation efforts to prevent any potential threats to biodiversity.
What is it called in particular when a high percentage of the species on earth dies off at a particular time?
These are called "mass extinctions", and there have been five such events (that we know of) on the Earth. These are generally caused either by astronomical impact events (such as the asteroid that killed off the dinosaurs 65 million years ago) or massive volcanic activity. The causes of these extinctions has been a matter of some dispute, since they happened so long ago.
When geologists refer to the big five' what are the referring to?
When geologist refer to the Big Five they are referring to the five mass extinctions on Earth. Some of these extinctions are the Paleozoic and Mesozoic eras.
How does the background rate of extinction differ from mass extinctions?
The background rate of extinction is much smaller than those that occur during a mass extinction. For example, carnotaurus sastrei went extinct during the mid-Cretaceous, when only a handful of dinosaurs went extinct. On the other hand, 65 million years ago, all dinosaurs went extinct during the K/T mass extinction event.
What are some extinctions other than dinosaurs?
dodos, elephant birds, passenger pigeons
What are the causes of planet destruction?
1. local star goes nova and obliterates planet with cast off stuff 2. planet falls into a star or black hole 3. impact from another object such as a large enough meteor, comet or other planet
