The outer layer of the Earth is made up of large slabs of rock called tectonic plates. Tectonic plates are usually made up of both continental plates and oceanic plates. Oceanic plates are usually thicker and more dense than continental plates. Convergence is when two plates collide; what ...
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...
Plateaus usually form when two tectonic plates collide, causing a slow upward movement of land. Some plateaus, such as the Colorado Plateau in the United States, still rise by a measurable distance every year. Plateaus can also be formed by volcanic activity, when layers of lava cool and hard...
Igneous rocks are formed directly from the cooling of magma. As the magma cools, it changes from a liquid state to a solid state and forms crystalline structures. Igneous rocks are subclassified according to their mineral composition and the size of their crystals. When magma cools slowly in m...
Convergent boundaries form when two tectonic plates are collide. A subduction zone occurs when one plate is forced beneath a lighter plate where it melts forming molten rock.
They found that earthquakes occurred in earthquake zones that outlined the tectonic plates on Earth. Formation of mountain rangesWhen two continental plates collide they form mountain ranges between the plates as the rocks are compressed. The Himalayan Mountains are an example of the Indian Plate ...
ridges. As the plates split apart, they do so at differing speeds, creating space—anywhere from a few to several hundred miles—between spreading margins. As the plates in this space continue to diverge, they do so in opposite directions. This lateral movement forms active transform boundaries...
Tectonic earthquakes occur when the Earth’s plates move. This can happen when two plates collide, when one plate slides underneath another, or when a plate is forced to move by the movement of the mantle. Effects: Tectonic earthquakes are incredibly powerful and can cause extensive damage. The...
When two oceanic plates converge, a deep trench forms, such as theMariana Trenchin the North Pacific Ocean which is believed to be the deepest point on Earth. These types of collisions can also lead to underwater volcanoes. Plate tectonics are responsible for the Mid-Atlantic Ridge. Thingvellir...
The Earth consists of several layers that sit on top of one another. The outermost layer is the lithosphere, and this layer is made from tectonic plates. Answer and Explanation:1 The lithosphere is broken into several tectonic plates that are composed of hard rocks. This layer floats on top...
