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 slowly over time.”,即构造...
Tectonic plates move due to a combination ofmantle convection,ridge push,slab pull, andtrench suction.The Earth's outer layer, called thelithosphere, is broken into large, rigid plates that float on the semi-fluid layer beneath, known as theasthenosphere. This movement is complex and results fr...

题目What causes earthquakes? A. Movement of tectonic plates. B. Changes in the weather. C. Volcanic eruptions. D. Human activities. 相关知识点: 试题来源: 解析 A。解析:地震是由地壳板块的运动引起的,A 选项正确。B 选项天气变化不会导致地震。C 选项火山喷发可能伴随地震,但不是地震的主要原因。D...
What are tectonic plates made of? Plate Tectonics The ground beneath us is moving, although it is at such a slow rate that it cannot be noticed by people. Over millions of years, however, this movement results in massive mountains and giant valleys. ...
They will move towards the equator over time C. Their body size will become much smaller D. They will start to hibernate all year round 相关知识点: 试题来源: 解析 B。解析:当板块运动使一些大陆向极点移动时,环境会变得寒冷。原本生活在这些大陆的温血动物为了寻找更适宜的温暖环境,会随着时间向...
the magma cools underwater it forms basalt, which makes up the majority of the oceanic crust. Examples of divergent faults include the Mid-Atlantic Ridge, a “crack” in the Atlantic Ocean where molten rock rises upward, and the boundary between the African and Arabian Plates in the Red Sea...
Tectonic plates move at a rate of 1 to 2 inches (3 to 5 centimeters) per year,according to National Geographic. That's about as fast as your fingernails grow! How many plates are there? Because Earth is spherical, its tectonic or lithospheric plates are fractured into dozens of curved sec...
A . The recent discovery of an unusual tectonic plate B . The effects of underwater riffs on plate boundaries located on land C . The development of a new technology for studying rifts located on land D . The process by which tecatonic plates are separated ...
The Earth's crust, or lithosphere, is divided into seven major areas called tectonic plates. Each plate drifts around slowly based on convection currents in the mantle. Even though the movement is slow, tectonic plates can have enormous impacts, creating impact phenomena, like mountain ranges, vo...
