Seven of the world's major tectonic plates make up around 84 percent of the Earth's total surface. This map shows those and also includes many other plates that are too small to label. Geologists refer to the very small ones as "microplates," although that term has loose definitions. The...
The movement of tectonic plates can cause ___. A. volcanic eruptions and earthquakes B. rain and wind C. storms and floods D. snow and ice 相关知识点: 试题来源: 解析 A。板块运动能引起火山喷发和地震。选项 A“volcanic eruptions and earthquakes”是火山喷发和地震;选项 B“rain and wind”是...
What are tectonic plates? A. Small pieces of the Earth's crust. B. Large pieces of the Earth's crust that move slowly. C. Pieces of the moon. D. Pieces of the sun. 相关知识点: 试题来源: 解析 B。解析:文章中提到“Tectonic plates are large pieces of the Earth's crust that move ...
A. When plates moved apart, it often led to the formation of large inland seas, which made the climate more humid B. Plate collisions usually caused mountains to rise, blocking the wind and resulting in a drier climate on one side C. As plates shifted, the distribution of land and sea ...
A. the mantle B. the crust C. the core 相关知识点: 试题来源: 解析 A。解析:地幔(the mantle)中的对流会影响板块构造(tectonic plates)的运动。地壳(the crust)是板块本身,地核(the core)虽然也对地球有重要影响,但不是直接影响板块运动的部分,所以B和C选项错误。反馈 收藏 ...
Tectonic plates are mainly composed of _. A. only soil B. only magma C. lithosphere which includes crust and upper mantle D. water and air 相关知识点: 试题来源: 解析 C。解析:板块主要由岩石圈组成,岩石圈包括地壳和上地幔。选项A说板块仅由土壤组成是错误的,土壤只是地壳表面很薄的一部分。选项...
The areas near the boundaries of tectonic plates have a high probability of ___ due to intense geological activities. A. 亲斯着去科亲斯着去科earthquake and volcano formation亲斯着去科亲斯着去科 B. 所理江到较者是边省置京除空层容区便半所理江到较者是边省置京除空层容区便半iceberg forma...
A. The rotation of the Earth B. The heat from the Earth's interior C. The gravitational pull of the Moon D. The influence of the Sun's rays 相关知识点: 试题来源: 解析 B。解析:地球内部的热量导致了地球板块的运动。地球内部的热量使地幔中的物质产生对流,从而推动板块运动。选项A地球的自转不...
The plate tectonic framework also allows for interpretation of park features in ancient settings, such as rock layers in Grand Canyon National Park deposited along a passive continental margin, and granite in the Sierra Nevada that formed during subduction.LILLIE, Robert J...
The theory of plate tectonics describes how the surface of Earth is split into an organized jigsaw of seven large plates of similar sizes and a population of smaller plates whose areas follow a fractal distribution. The reconstruction of global tectonics during the past 200 million years4 suggests...
