It oozes up into the gap and hardens into solid rock, forming new crust on the torn edges of the plates. Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created. ...
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...
What is the difference between a convergent and a divergent plate boundary? What are lithospheric plates? At which kind(s) of plate boundaries does subduction occur? What are Earth's plates? What is the Mariana Trench and its tectonic plates?
What do tectonic plates do at divergent boundaries? What do tectonic plates move on? What are some examples of plate tectonics? What tectonic plates caused the Boxing Day tsunami? What is a geological disaster? What are the names of the major tectonic plates? Which layer of earth is made up...
The Theory of Plate Tectonics explains how and why crustal plates drift around on the surface of the Earth. Tectonic plates have three major boundaries. Divergent boundaries are areas on the Earth’s surface where two plates are moving apart. Convergent boundaries are areas where tectonics plates ...
The boundaries of tectonic plates are typically where Earthquakes, volcanos, tsunamis occur and new mountains form. Divergent boundaries occur where... Learn more about this topic: Plate Tectonics | Definition, Theory & Summary from Chapter 7/ Lesson 5 ...
A plate boundary is a location where two tectonic plates meet. There are three different types of tectonic plate boundaries, which are defined by the relative motion of each plate. The three types of plate boundaries are divergent, convergent, and transform. These plate boundaries can occur both...
Divergent boundariesoccur where plates are spreading apart or separating from one another. This spreading is caused by convective forces in the molten magma below them. When this occurs between two oceanic plates, as they slowly spread apart, this fluid basalt lava fills the gap and quickly solid...
Tectonic Plate Boundaries As the plates of the earth move, three types of tectonic plate boundaries occur. Divergent boundaries occur when two plates move in opposite directions, such as the pulling apart of North and South America from Europe and Africa, which, according to the U.S. Geological...
What is used to determine earthquake risk? What is the fault of an earthquake? What do tectonic plates do at divergent boundaries? What tectonic plates caused the 2004 tsunami? What is a seismic event? What are three types of tectonic plate boundaries?
