Answer:
The end-Permian mass extinction, and the one that preceded it by nine 9 million years, the end-Guadalupian mass extinction, were both related to flood basalt eruptions, which caused an episode of greenhouse warming and the onset of deep sea anoxia.
Explanation:
The Permian-Triassic mass extinction was a very large mass extinction of plant and animal species that occurred about 251 million years ago, during the transition from the Permian to the Triassic. Several large-scale extinctions are known in Earth's history, of which the Permian-Triassic mass extinction is the largest.
95% of all marine species and about 70% of terrestrial vertebrates died out at the Permian / Triassic transition. It was also the only time that the insects also became extinct on a large scale; about 1/3 of all insect species disappeared during the Perm-Triassic mass extinction.
It is now believed that this extinction wave occurred within a very short time (about 1 million years) by geological standards. Evidence of a less severe wave of extinction, 9 million years earlier, has also been found in Greenland.
The Permian-Triassic transition was characterized by intensive volcanism. During this period, the Siberian Steps, a 200,000 km² basalt plateau, literally arose from the most extensive volcanic activity in Earth's history. As a result of this volcanism, the climate may have changed enough to produce a mass extinction.
Well, if its only two feet its a wake
Answer:
Correct answer is widening of gender differences.
Explanation:
During Neolithic Revolution many new important changes occurred that led to improvement of life and better life conditions.
As people started settling more, they gained more reliable food supplies, while also certain labors were differentiated including hunting, food gathering...
Gender differences were not widened that much as male dominance already existed.
Answer:
Thermal power and irrigation remained the two main water users in 2015, and the total withdrawal for thermal power decreased but increased for irrigation.
Answer:I can think of many things that extrapolating on incomplete data can cause. First and foremost, the subject of climate change and the use of fossil fuels. If we continue down the path of green emery, the country will become so poor. There is not enough data to forecast what the cost of this green energy will cost the average house hold.
