However, almost every other type of landslide is possible, including highly disaggregated and fast-moving falls; more coherent and slower-moving slumps, block slides, and earth slides; and lateral spreads and flows that involve partly to completely liquefied material (Keefer, 1999).
Slides are also sub-classified by the form of the surface(s) or shear zone(s) on which movement happens. The planes may be broadly parallel to the surface ("planar slides") or spoon-shaped ("rotational slides"). Slides can occur catastrophically, but movement on the surface can also be gradual and progressive.
The most dramatic orogenic belt on the planet is the one between the African plate and the Indo-Australian plate on one side (to the south) and the Eurasian plate on the other side (to the north). This belt runs from New Zealand in the east-south-east, through Indonesia , along the Himalayas , through the Middle East up to the Mediterranean in ...
One explanation for Venus's lack of plate tectonics is that on Venus temperatures are too high for significant water to be present. [101] [102] Earth's crust is soaked with water, and water plays an important role in the development of shear zones. Plate tectonics requires weak surfaces in the crust along which crustal slices can move, and it ...
A landslide, also called a landslip, [10] is a relatively rapid movement of a large mass of earth and rocks down a hill or a mountainside. Landslides can be further classified by the importance of water in the mass wasting process. In a narrow sense, landslides are rapid movement of large amounts of relatively dry debris down moderate to steep ...
The study included data from 1993 through 2010, and showed that the pumping of as much as 2,150 gigatons of groundwater has caused a change in the Earth’s tilt of roughly 31.5 inches. The ...
The original calculations assumed that the Earth has the same density throughout - and the gravitational force changes as you approach the center, much like the weight of a spring that bounces up ...
Aaron Judge should have been called for interference for his slide on a botched double-play attempt that sparked New York’s winning rally Sunday at Milwaukee, crew chief Andy Fletcher ...
