It turns into a river because of all the water the mountains have and then creates a path. Rivers cause erosion. Runoff from rivers cause rocks to erode. Because of gravity, runoff, and the sediment it has, to move downhill. An example of this sheet erosion.
There are volcanoes happens are hidden because it occurring under the oceans, furthermore, Also, many of them happen in the forest. In contrast, the earthquake occurs and happens in any place randomly. It happens in the oceans and in the continents. The source of the earthquakes is the melt area, the first layer under the surface of the ground. Second, the process of the two natural events is different than each others.
Rain, snow, and sleet return water from the atmosphere to Earth's surface. On the ground, the water cycle continues with infiltration, the process in which surface water seeps into the soil where it can become groundwater. The amount of water that infiltrates into the ground depends on many factors, such as soil type and rock type. Topography also influences infiltration — a steeper slope forces the water to run off more quickly, preventing much infiltration. In addition, if the soil is already saturated with water, it cannot absorb much more, which leads to an increase in runoff.
Global warming has been a highly debated topic for quite a bit of time now. Is it or is it not happening? Global warming is an increase of temperature that causes related changes in climate and the environment. This has been seen in Antarctica especially. The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already.
The actual speed of P and S seismic waves depends on the density and elastic properties of the rocks and soil through which they pass. In most earthquakes, the P waves are felt first. The effect is similar to a sonic boom that bumps and rattles windows. Some seconds later, the S waves arrive with their up-and-down and side-to-side motion, shaking the ground surface vertically and horizontally. This is the wave motion that is so damaging to structures.
Wegener's theory also provided an alternate explanation for the formation of mountains (orogenesis). The theory being discussed during his time was the "Contraction theory" which suggested that the planet was once a molten ball and in the process of cooling the surface cracked and folded up on itself. The big problem with this idea was that all mountain ranges should be approximately the same age, and this was known not to be true. Wegener's explanation was that as the continents moved, the leading edge of the continent would encounter resistance and thus compress and fold upwards forming mountains near the leading edges of the drifting continents. The Sierra Nevada Mountains on the Pacific coast of North America and the Andes on the coast of South America were cited.
But now due to the global distribution of these major plates it has been proposed by Wegener and his successors that convection currents in the mantle are the cause of the movement of plates. And it is through the movement of these large plates that cause many different processes that can each affect the landscape in its own way. Fold Mountains: When there is collision between two continental plates, the silica rich (quartz and feldspar rich) continental plates force against each other along the plate boundary as they never subduct due to their
The force of one plate being dragged under another causes intense friction and the pressure increases. Eventually, there is so much pressure that the plates suddenly jolt, causing an earthquake. Where an oceanic plate meets a continental plate, sediments are thrust upwards. Due to the friction caused by the plates scraping against each other, the temperature in the mantle increases. Magma rises forming a long chain of volcanic fold mountains for example the Andes.
Erosion is powerful among desert and glacial areas. Erosion is powerful because of high winds and the way rocks along with sand dunes in the desert are formed. Water erosion also plays a huge part in redeveloping the landscape of deserts by transferring sand from one region to another. Glaciers are created by the thickening of ice and snow. As a result of glaciers tends to float toward the outside using the pressure of its own weight.
Alfred could not explain how the huge masses of land could have moved so far. The major means for the lithospheric plates to float on the asthenosphere comes from the process of convection in the mantle of the Earth. Heat from the outer core rises in the mantle and “melts” the upper part, which is called the asthenosphere. The plates of the lithosphere move in three main ways. There are divergent boundaries where the plates are moving away from each other and new land is formed as magma is released from inside the mantle.
