Can a dormant volcano become active or extinct? 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.
Can a volcano become extinct? The tectonic plate carrying the islands is slowly moving, so that volcanoes are cut off from the hotspot underneath. Eventually they go extinct, while the hotspot creates a new volcano further to the East. Some volcanoes look extinct, but it might just be a long time since they’ve erupted.

is the great wolf extinct?
The gray wolf was almost extinct in the lower 48 states of the United States by the mid 1900s. Thanks to the Endangered Species Act, the gray wolf may be well on its way to recovery. Issues still remain as the wolf’s successful repopulation may signal an end to its full protection under federal laws.
do 200 species extinct every day?
Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the “natural” or “background” rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.

The answer to your question is yes, bees are endangered. And because bees are endangered, nature, ecosystems, and our food supply are also at risk.
how did mammals evolve after the extinction of dinosaurs?
“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.
what happened after dinosaurs became extinct?
After the dinosaurs’ extinction, flowering plants dominated Earth, continuing a process that had started in the Cretaceous, and continue to do so today. But all land animals weighing over 25 kilogrammes died out. ‘What we’re left with are basically the seeds of what we have today.
Is Basque a revived language?
Growing Use of Once-Banned Euskera : Basques Revive Their Native Language. Inhabitants of the hilly Basque region of northern Spain were once banned from speaking or writing their national language. But Euskera is now being revived with an official stamp of approval.
What happened at the Eocene Oligocene boundary?
Following the Eocene/Oligocene boundary, deep-water temperatures began a long-term warming over the next 18 million years (33–15 Ma). The coldest deep-water temperatures of 3°C were recorded at 33 Ma, while temperatures reached 9°C at ∼25 and ∼15 Ma (Figure 7B).
How many species of animals have gone extinct due to poaching?

What has been extinct recently?
The Spix’s macaw is a recently extinct animal from near the Rio São Francisco in Bahia, Brazil. In 2019, the bird known as the “Little Blue Macaw” because of its vibrant blue feathers was declared extinct in the wild.
Does dark matter have positive mass?
In the first simulation, all particles have positive mass. In the second one, 84% of particles (the observed fraction of dark matter) have a negative mass. The positive mass simulation has the initial random inhomogeneities amplified by gravity to form concentrations and voids at an accelerated rate.
What would’ve happened if dinosaurs didn’t go extinct?
“If dinosaurs didn’t go extinct, mammals probably would’ve remained in the shadows, as they had been for over a hundred million years,” says Brusatte. “Humans, then, probably would’ve never been here.” But Dr. Gulick suggests the asteroid may have caused less of an extinction had it hit a different part of the planet.
What will happen when the Y chromosome goes extinct?
In a 2016 paper, she points out that Japanese spiny rats and mole voles have lost their Y chromosomes entirely – and argues that the processes of genes being lost or created on the Y chromosome inevitably lead to fertility problems. This in turn can ultimately drive the formation of entirely new species.
How do you raise the purity of Celestial Crystals?
Purity can only be increased by splitting maximum-size crystals in Liquid Starlight. Purity provides a transmission efficiency multiplier to things that focus or redirect starlight; the multiplier is the square root of the purity (so 25% purity provides a 50% multiplier).
Why are they extinct now?
Recent estimates suggest that extinction threatens up to a million species of plants and animals, in large part because of human activities such as deforestation, hunting, and overfishing.

The answer to your question is yes, bees are endangered. And because bees are endangered, nature, ecosystems, and our food supply are also at risk. However, there are a few ways you can help bee populations.
How does dark matter interact with normal matter?
Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
