What is present in the mantle that can melt the crust that moves downward? What is plate tectonics? What is the largest tectonic plate called? Which layer of the geosphere supports the tectonic plates? What theory states that plates move around on the asthenosphere?
The Pacific Plate moves in a northeasterly direction relative to the North American Plate. The San Andreas fault is also called a right-lateral strike slip fault. If you look across the fault it looks like the land has moved to the right.This describes what is plate tectonics theory of ...
The process of subduction forms deep sea trenches. Subduction happens when one tectonic plate moves under another tectonic plate. One plate that is... Learn more about this topic: Deep Ocean Trench | Definition, Formation & Examples from
A reverse fault is one in which the hanging wall moves up relative to the footwall. What causes faulting? A fault is formed in the Earth's crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in ...
In simple terms, it works to measure the up and down movements of theearth, by using a weight attached to a spring, which will move up and down depending on vibrational movements in the ground. A pen is attached which records these movements on paper every time the weight moves. ...
The movements begin when the compaction is so dense that it moves under the pressure of its weight. It is estimated that more than 75% of the world’s freshwater is currently locked in these frozen reservoirs. The glaciers include the Greenland Ice Sheet, the Antarctic Ice Sheet and the Ca...

A lake (from Latin lacus) is a terrain feature (or physical feature), a body of liquid on the surface of a world that is localized to the bottom of basin (another type of landform or terrain feature; that is, it is not global) and moves slowly if it moves at all. On Earth, a ...
In some cases, coupling between the cold surface and the hot mantle is reduced, and plates move slowly while the mantle moves much faster. We return to their model to investigate the physics that causes these distinct plate/mantle relationships, derive mathematical descriptions for this behavior, ...
Possibly the world's most famous building shock absorber is a giant, 660-tonne ball inside the Taipei 101 skyscraper in Taiwan. If an earthquake (or high wind) makes the tower sway in one direction, the ball (mounted onhydraulic rams) moves the other way, effectively canceling out the ...
