A. It is destroyed B. It is compressed C. It is created 相关知识点: 试题来源: 解析 C。解析:在离散型板块边界,板块相互分离,地幔中的岩浆上涌,冷却后形成新的地壳,所以地壳是被创造出来的。而在汇聚型板块边界地壳会被破坏,板块被压缩是汇聚型板块边界板块碰撞时的状态,所以这题选C。
A. It is being compressed B. It is being stretched C. It is being subducted D. It is being transformed 相关知识点: 试题来源: 解析 B。解析:在背离型(divergent)板块边界,岩石圈主要是被拉伸(stretched)。A选项compressed是被压缩,这是汇聚型板块边界的情况;C选项subducted是俯冲,与背离型板块边界无关...
When two tectonic plates slowly move away from each other it creates a divergent boundary. As this happens, magma rises from the Earth’s mantle into the widening gap between the plates. When it reaches the surface it forms solid rock, creating new crust material. Divergent plate boundaries of...
What happens at a transform boundary? Geologic Processes The geologic processes of the earth may seem to be happening very slowly, but they still affect our everyday lives. For example, the different types of boundaries formed by tectonic plates cause different geologic events such as volcanoes an...
Learn a transform boundary definition and what happens at transform plate boundaries and what they create. Also see transform boundary examples and...
The tectonic plates boundaries are also sometimes called fault lines. Fault lines are infamous as the location of earthquakes and volcanoes. A great deal of geologic activity happens at these boundaries. At divergent plate boundaries, the plates move away from each other, and lava often is present...
As this process continues, the activity causes a ridge in the seafloor. An example of an oceanic divergent boundary is the Mid-Atlantic Ridge. Iceland actually sits atop the Mid-Atlantic Ridge. Eventually, the island will be split into two separate landmasses because the plates will continue to...
Which plate boundary and movement commonly create non-volcanic mountains? What happens when tectonic plates shift? On which layer of the earth do tectonic plates float? What is a tectonic cycle? What is the tectonic setting of a thrust fault? How do tectonic plates cause earthquakes and volcanoe...
Discuss what an effusive ocean-ocean divergent boundary is. What is the salinity of the mesopelagic zone? What type of crust is involved in divergent boundaries? What is another name for divergent boundaries? What happens at a convergent boundary? What are three types of tectonic plate boundaries...
