“plates” that float on the asthenosphere. As a result of the plates floating on the more fluid asthenosphere, there is a pattern of drift between the continents; the plates are moving between 1-10 cm/year Plate Tectonic Theory can explain the existence of earthquakes, volcanoes, mo...
About 1500 active volcanoes can be found across the world though countless others are on the ocean floor.世界各地大约有1500座活火山，但还有无数活火山位于海底。Most volcanoes whether on land or underwater are located where tectonic plates meet.无论是在陆地上还是在水下，大多数火山都位于地壳板块交...
10. Volcanoes are usually where tectonic plates meet. Volcanoes often occur where tectonic plates meet. Tectonic plates are like puzzle pieces that cover the Earth. They are underneath the ground. The plates always move very slowly but when the plates move suddenly they often cause an earthquake....
选项只是将not very predictable换成了unpredictability而已。 第18题答案:(the tectonic) plates 对应原文:C部分第四段:and you can see the rough outlines of what are called tectonic plates – the plates which make up the earth’s crust and mantle. 解析:阅读原文中有三次提到了crust,分别是A部分的第...
Italy's position on theconverging boundaryof the African and Eurasian tectonic plates makes it a volcanically active region. This geological setting has given rise to several notable volcanoes, including the active Mount Etna, Stromboli, Mount Vesuvius, and Vulcano, as well as dormant giants like ...
There are hundreds of active volcanoes on earth, most of them in the Circum-Pacific "ring-of-fire" at tectonic plate boundaries where a sea plate moves under a land plate at what is called a subduction zone. A volcano is considered active if it has erupted at least once in the past ...
Volcanoes form on the boundaries of the tectonic plates that continuously move inside the Earth. There are 17 such tectonic plates inside the Earth’s Crust. The Earth is divided into several parts such as the Crust, Upper Mantle, Mantle, Outer Core, Inner Core. These tectonic plates exist ...
Although most volcanoes are found at convergent or divergent plate boundaries, intraplate volcanoes are found in the middle of a tectonic plate. The Hawaiian Islands are the exposed peaks of a great chain of volcanoes that lie on the Pacific plate. These islands are in the middle of the Pacifi...
Tectonic plates are huge pieces of the earth's crust, which fit together like pieces of a puzzle. The plates are constantly moving on top of a layer of solid rock called the mantle (地幔). Sometimes these plates collide, move apart, or slide next to each other, which shows the normal ...
re on Earth. Instead, they’re more or less randomly scattered over Venus’ surface. Well, that’s significant: [recapping] Venus has mostly shield volcanoes, and they’re randomly scattered—that indicates that Venus does not have moving tectonic plates, and that’s a big difference compared...
