what is the meaning of extinct volcano? Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future.
Why are volcanoes extinct? What causes volcanoes to go extinct? Simply put, they’re cut off from their supply of lava. This is where a chamber of magma underneath the surface of the Earth finds its way to the surface through weaknesses in the crust.
What is being done to protect blue whales? All blue whales are protected under the MMPA and ESA. Our work strives to protect blue whales by: Reducing vessel strikes. Responding to dead, injured, or entangled blue whales.
Is paleontology still around? Modern paleontologists have a variety of tools that help them discover, examine, and describe fossils. Electron microscopes allow paleontologists to study the tiniest details of the smallest fossils.

how does extinction affect us?
Well, according to new research published December 2 in Nature, the answer is yes—healthy biodiversity is essential to human health. As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species.
how did the extinction of the dinosaurs affect mammalian evolution?
“When the dinosaurs went extinct, access to different foods and environments enabled mammals to flourish and diversify rapidly in their tooth anatomy and evolve larger body size,” said lead author Madelaine Atteberry from the University of Colorado Geological Sciences Department.

The spread of modern humans across Europe is associated with the demise and ultimate extinction of Neanderthal populations 40,000 years ago, likely due to competition for resources.

The combination of bigger brains, small size, their ability to eat a wider palate of foods, and their ability to fly ultimately may have helped birds survive the last mass extinction.
how long ago did the tasmanian tiger go extinct?
The Thylacine became extinct on the Australian mainland not less than 2000 years ago. Its decline and extinction in Tasmania was probably hastened by the introduction of dogs, but appears mainly due to direct human persecution as an alleged pest.
are extinct volcanoes really extinct?
A volcano which has not erupted in the past 10,000 years is often listed as extinct. The extinct volcano no longer has a lava supply. An extinct volcano is no longer near an active geologic hot spot, if it ever was. Volcanologists sometimes can’t tell whether a volcano is extinct or dormant.
do predators eat their prey to extinction?
The mere sounds or smells of predators seem to hurt some prey’s chances for survival. In the wild, a predator that eats too much of its prey can drive that species toward extinction.
when did other human species go extinct?

How long does a volcano have to be inactive to be considered extinct?
A volcano is currently active if it is erupting lava, releasing gas or generating seismic activity. An active volcano is labelled dormant if it has not erupted for a long time but could erupt again in the future. When a volcano has been dormant for more than 10 000 years, it is considered extinct.
Do predators drive their prey extinct?
Predators may increase the probability of prey extinction resulting from a catastrophic disturbance both by reducing prey population size and by changing ecological traits of prey individuals such as habitat characteristics in a way that increases the vulnerability of prey species to extinction.
What does increasing fortitude do in Ark?
If you add a point to fortitude, it becomes 51. You also increase your insulation, which is like resistance to both hot and cold. Each time you level up fortitude, you get an extra 4.5 points into your insulation. So with one point in fortitude, your hypo and hyperthermic insulation is 4.
What are the human causes of species extinction?
How do humans cause extinctions? Many species have become extinct because of human activities such as hunting, overharvesting, the conversion of natural ecosystems to cropland and urban areas, pollution, and other alternations or destruction of natural environments.
