A。解析:在板块构造学说中,离散型板块边界(divergent plate boundary)处板块是相互分离(move apart)的。B选项plates move together是板块汇聚型边界的情况,C选项plates slide past each other是板块转换型边界的情况,根据板块运动知识,本题答案为A,这里没有特殊语法运用,主要考查对板块运动不同边界情况的词汇理解。反...
Types of plate boundaries There are 3 types of plate boundaries, depending on how the plates move relative to each other: Divergent boundariesoccur where two plates move apart from each other. This happens at the mid-ocean ridges, where seafloor spreading and volcanic activity continuously add new...

B。解析:在板块构造理论中,汇聚边界(Convergent boundaries)通常伴随着板块的碰撞挤压,这种剧烈的地质活动使得地下深处的物质被带到地表附近,容易形成贵金属矿床,像金和银等。离散边界(Divergent boundaries)主要是板块分裂,更多与岩浆活动相关,常和新的大洋地壳形成以及一些金属硫化物矿床有关,而不是主要与油气矿床相关,所...
Tectonic Plate Boundaries Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. How can two plates move relative to each other? Divergent plate boundaries: the two plates move away from...

As the name suggests, divergent boundaries are tectonic boundaries where plates "diverge" or are tugged apart. This motion creates giant troughs on land, such as the East Africa Rift. In the ocean, this same process createsmid-ocean ridges. Hot magma from Earth’s mantle wells up at these...
divergent boundaries, also called spreading centers; and conservative transform boundaries. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The lateral relative movement [2] of the plates varies, though it is typically 0– 100 mm ...
