The ancient Chinese did not understand that earthquakes were zhanghengcaused by the shifting of tectonic plates in the Earth's crust; instead, the people of the ancient Zhou Dynasty (zhōu cháo 周朝) explained them as disturb...
Passage Three The theory of plate tectonics describes the motions of the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere is divided into a few dozen plates of various sizes and shapes, in general the ...
The vector diagram for the relative motion of the three plates during the late Cainozoic suggests that the Juan de Fuca Plate is being thrust obliquely below the American Plate at 2.5 cm yrin a direction of N 35掳 E (ref. 1).doi:10.1038/250133a0R. A. Stacey...
1.(used with a sing. verb)A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interaction of the earth's lithospheric plates. ...
The cracks in between these plates are boundaries. There are three main types of boundaries between the tectonic plates. The first is a divergent boundary, which occurs when two tectonic places move away from each other. Volcanic activity is common along this boundary A rift valley can also be...
The country sits at the boundary three pieces of Earth’s crust(地壳)that fit together like a jigsaw puzzle(拼版玩具)— 4 (call) tectonic plates.(板块)As one plate slides slowly 5 another, stress builds up over time. At some point, the stress becomes so great that all the energy ...
The types of plate boundaries are primarily classified into three main categories: Divergent, Convergent, and Transform. Each of these boundaries can result in specific geological features and processes. 1. Divergent Boundaries Divergent boundaries occur where two tectonic plates are moving away from eac...
Occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle. ...
阅读理解Earth's surface(表面) is shaped by the movement of tectonic(地壳构恋的) plates that move into, against, or away from one another. Scientists study what happens to Earth's crust(外壳) at the boundaries of these plates. There are three kinds of boundaries: divergent boundaries, transf...
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...
