虽然海平面下降与12次灭绝事件有关,但只有7次涉及物种的重大损失。另一方面,火山已导致11个ELE,所有这些都很重要。末端二叠纪,末三叠纪和末端白垩纪的物种灭绝与火山爆发有关,称为洪水玄武岩事件。火山通过释放灰尘,硫氧化物和二氧化碳来杀死,通过抑制光合作用使食物链坍塌,使酸雨对陆地和海洋造成毒害,并产生全球变暖。下次你去黄石公园度假时,花一点时间停下来思考火山喷发时的影响。至少夏威夷的火山不是行星杀手。最终,大规模物种灭绝的最终原因是全球变暖或全球变冷,通常是由其他事件之一引起的。全球降温和冰川作用被认为是末奥陶纪,二叠纪 – 三叠纪和晚泥盆世物种灭绝的原因。虽然温度下降导致某些物种死亡,但随着水变成冰,海平面下降的影响更大。全球变暖是一种更有效的杀手。但是,不需要太阳风暴或红巨人的极端加热。持续加热与古新世 – 始新世热量最大值,三叠纪 – 侏罗纪物种灭绝和二叠纪 – 三叠纪物种灭绝有关。大多数问题似乎是高温释放水的方式,将温室效应添加到等式中并导致海洋中的缺氧事件。在地球上,这些事件总是随着时间的推移而平衡,但一些科学家认为地球有可能走向金星的道路。在这种情况下,全球变暖将使整个地球消毒。

新加坡南洋理工大学环境学Essay代写:海平面下降

Although sea level decline was associated with 12 extinction events, only 7 major losses were involved in the species. On the other hand, the volcano has led to 11 ELEs, all of which are important. The extinction of the end Permian, Late Triassic and Terminal Cretaceous is associated with volcanic eruptions and is known as the flood basalt event. Volcanoes are killed by the release of dust, sulfur oxides and carbon dioxide, which causes the food chain to collapse by inhibiting photosynthesis, causing acid rain to poison land and sea and produce global warming. Next time you go to Yellowstone for a holiday, take a moment to stop and think about the effects of the volcanic eruption. At least Hawaii’s volcano is not a planet killer. Ultimately, the ultimate cause of mass extinction is global warming or global cooling, usually caused by one of the other events. Global cooling and glacial effects are thought to be the cause of the extinction of the Permian-Triassic and Late Devonian species. Although the temperature drop causes some species to die, as the water turns into ice, the effect of sea level decline is greater. Global warming is a more effective killer. However, there is no need for solar storms or extreme heating by the Red Giant. Continued heating is associated with the Paleocene-Eocene heat maximum, the Triassic-Jurassic species extinction and the Permian-Triassic species extinction. Most of the problems seem to be the way water is released at high temperatures, adding the greenhouse effect to the equation and causing anoxic events in the ocean. On Earth, these events are always balanced over time, but some scientists believe that the Earth may be on the way to Venus. In this case, global warming will disinfect the entire planet.
