The subduction of plate tectonics causes an ocean trench to form. This means one of the Earth's tectonic plate slides under another tectonic plate.
When forming an ocean trench, a heavy tectonic plate's edge presses against a lighter tectonic plate's edge. At the place where the plates meet, the heavier tectonic plate subducts below the lighter tectonic plate to form the subduction zone. The subduction zone is the site called an ocean trench. Ocean trenches most commonly form when a tectonic plate comprised of oceanic crust meets a tectonic plate comprised of continental crust, although some rarer trenches have been formed by two layers of oceanic crust meeting.Learn More
The four types of erosion are sheet erosion, rill erosion, gully erosion and splash erosion. Erosion is defined as the withering away of the surface of land by either rain or irrigation water, wind or ice.Full Answer >
Corrosion is a process by which a chemical reaction eats away at a metal. An example of a chemical reaction that causes corrosion is the oxidation of iron by water in an electrolytic process. The product of this reaction is rust.Full Answer >
Although both are methods by which liquid water transitions into a gas, evaporation describes the process in which heat changes standing water into water vapor, while transpiration refers to the process plants undertake that draws water from the ground and releases it into the air.Full Answer >
Acid rain has many environmental side effects, but its impact is largely seen on water sources and aquatic environment, such as lakes, wetlands and streams, explains National Geographic. Acid rain reduces the alkalinity, the capacity of water to neutralize acid, and thus increases the acidity of the water, leading to a weaker ecosystem. Acidic water is also toxic to fish, clams, crayfish and other aquatic animals.Full Answer >
