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.
These P waves are able to travel through both solid rock, such as granite mountains, and liquid material, such as volcanic magma or the water of the oceans. The slower wave through the body of rock is called the secondary or S wave. As an S wave propagates, it shears the rock sideways at right angles to the direction of travel. If a liquid is sheared sideways or twisted, it will not spring back, hence S waves cannot propagate in the liquid parts of the earth, such as oceans and lakes. 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.
Where do these rocks come from? Sedimentary rocks come from the very thing they are named after; sediment. These rocks originate from weatherization and a few other processes over a long period of time. For example, if a mineral is stripped from some rocks during weatherization and are carried to a body of water, the minerals will eventually settle at the bottom of the lake and through some other processes settle down and form rocks (Murck, Skinner, & Mackenzie, 2008). Dead plants and animals, along with minerals already at the locations help to create the sedimentary rocks and their unique characteristics.
Each boundary between 2 plates have the capability of being a different type of boundary. The 3 types of boundaries are destructive (plate being destroy as another passes over the top), constructive plates moving apart from each other creating new crust) and conservative (sliding past one another). Each boundary will have its own key characteristics. Firstly, we will look at destructive plate boundaries. These are boundaries where the plats move towards each other but 1 plate travels underneath (subduction).
Second, the process of the two natural events is different than each others. The volcano usually happens and forms near the plates boundaries of the ground. First, the crust is moving a little bit and causing melt because of decreasing the
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
Rising air currents take water, as vapor, up into the atmosphere; with the water form of "evapotranspiration," which is water transpired or from plants and that has evaporated from the soil. The cooler temperatures in the atmosphere cause it to condense in the clouds, which float around in the air until they fall from the sky as precipitation. Some precipitation falls as snow and can accumulate as hail, where it can stay, as ice crystals, for thousands of years. In warmer climates, snow melts, then warmer spring and summer months, and that water flows into streams and rivers, which eventually return it to the ocean, or into the groundwater, which eventually reach underground purifiers. Over time, the water continues to flow, some to return to the ocean, where the water cycle renews itself.
The cycle returns carbon to the atmosphere through volcanoes. Earth’s land and ocean surfaces sit on several moving crustal plates. When the plates collide, one sinks under the other, and the rocks it carries melts under the extreme heat and pressure. The heated rock recombines into silicate materials, releasing carbon dioxide. When volcanoes erupt, they vent the gas to the atmosphere and cover the land with fresh silicate rock to start the cycle
How to predict an volcanic eruption Ground Deformation Ground deformation is the change in shape that happens before during or after a volcanic eruption. This happens because the sides of the volcano change shape because the magma in many ways to measure the change of shape of the volcano, like leveling, triangulation and more recently using continuous Global Positioning System (CGPS). It is also possible to use lakes as large tilt meters. Tilt meters measure the tiny degrees of tilt or slope on land. This is one of the oldest methods of knowing when ground deformation was caused because of rising lava.
Metamorphic alteration causes the texture and mineral composition to change. Recrystallization is the process of the formation of a new texture. Metamorphic rocks are usually classified as either regional or thermal. Regional metamorphic rocks are mostly formed by pressure instead of heat. Different types of rocks are created based on the amount of pressure.
