Volcanic eruptions are more common in certain areas due to plate tectonics. Which area is most likely to have frequent volcanic eruptions? A. Areas far from any plate boundaries B. Areas where plates are slowly moving away from each other C. Areas where plates are sliding horizontally against ...
The editor reflects on the role of volcanic eruptions in global warming. He mentions the tendency of the aerosol from the eruption to block the solar radiation. He stresses the role of the warming effect of volcanism in climate regulation and in the increase of atmospheric carbon dioxide CO2. ...

Basaltic eruptions are the most common form of volcanic eruption, and for the most part, they involve relatively tame magma activity. Occasionally, however, the magma activity results in highly explosive and hazardous eruptions. The latter are known as Plinian eruptions, after the Ancient Roman writ...
For almost all of the volcanic eruptions we've ever seen, this relationship holds. But when researchers consider supervolcanoes—behemothslike the one beneath Yellowstonethat can spew out up to 120 cubic miles of magma—the mathematical rule breaks down. Supervolcanic eruptions are so rare that...
A. So B. But C. Or D. And 相关知识点: 试题来源: 解析 A。“Volcanic eruptions are dangerous”(火山喷发很危险),“people should stay away from active volcanoes”(人们应该远离活火山),前后是因果关系,因为危险所以要远离,用“So”表示“所以”。反馈 收藏 ...
The smallest, simplest, and most common type of volcanoArticle by: Hobart M. King, PhD, RPGCumbre Vieja Volcano on the Canary Island of La Palma, has been erupting cinders, volcanic ash and lava from multiple cinder cones high on Cumbre Vieja Ridge. These eruptions are powered by jets of...
我们可以根据常识判断,火山喷发会引发巨大的声响,所以选项D中的sounds(声音)最符合题目要求,是正确答案。其他选项与自然现象“火山喷发”不太相关,因此不是正确答案。 故本题答案选D。 movements:运动,动作 waves:波浪 impacts:撞击 sounds:声音 Volcanic eruptions:火山爆发反馈 收藏 ...
Biologists call it “homeostasis”; physicists call it entropy, or a “state of thermodynamic equilibrium.” Either way, nature’s final, healthy state is balance, harmony. Volcanic eruptions, earthquakes, massive storms, and other menaces indicate nature’s level of imbalance. These are the valv...
A. The crust blocks all the magma from the mantle during eruptions B. Magma from the mantle rises through the crust because of pressure differences C. The mantle shrinks away from the crust during volcanic eruptions D. The crust absorbs all the heat from the magma of the mantle ...
