A. Near a mid - ocean ridge (divergent boundary). B. Near a subduction zone (convergent boundary). C. Near a transform fault. D. In the middle of a stable continental plate. 相关知识点: 试题来源: 解析 A。解析:在大洋中脊(mid - ocean ridge,离散边界)附近,有强烈的岩浆活动。岩浆从地幔...
At DIVERGENT BOUNDARIES, plates move away from each other. As they move, they create mountain ranges, volcanoes, rifts (areas where the crust pulls away from the upper mantle), and new ocean floors. (1) Tap the mid-ocean ridge on the seafloor. What happens? As the plates move away ...
a. decompression melting of rising hot mantle rock b. the addition of water to the mantle during subduction c. the ascent of molten material from the outer core to the surface. d. heating of the Earth during magnetic polarity reversals Decomp...
Volcanic activity is due to subduction of the Indo-Australian tectonic plate as it moves northward toward mainland Asia. What type of tectonic plate interaction causes the eruption? The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and...
The terms "convergent" and "divergent" refer to tectonic plate boundaries and not the plates. The North American Plate has both convergent and divergent boundaries
They occur along the divergent plate boundaries, where a new ocean crust is formed due to the spreading of tectonic plates. As they grow apart, the molten rock beneath the earth’s crust rises to the seafloor through cracks generating significant volcanic eruptions containing lava and basalt. ...
In the area you have selected (Mozambique) earthquake hazard is classified as medium according to the information that is currently available.
(the ophiolite suite) is generated between them. The ocean basin in this stage is comparable to the Red Sea today. As the ocean basin widens the stretched and thinned edges where the two continents used to be joined cool, become denser, and sink below sea level. Wedges of divergent ...
The East Pacific Rise is a site of major seafloor spreading in the Ring of Fire, located on the divergent boundary of the Pacific Plate and the Cocos Plate (west of Central America), the Nazca Plate (west of South America), and the Antarctic Plate. The largest known group of volcanoes ...
Supplementary Material shows interactive maps demonstrating the main types of plate motion, which include spreading (divergent), subduction (convergent), and lateral sliding (transform), and the change in size of land due to plate movement. For example, the North America Plate is moving west ...
