A glacial outwash plain is a field of alluvial sediment deposited by the flow of glacial meltwater. Other types of outwash plains can form under different circumstances, but glacial outwash plains tend to be located downhill of glaciers that experience partial melting during warm seasons.Know More
Glaciers form when snow deposited on the ground fails to melt completely and builds up to form a large mass of compacted ice. Because of the way they form, glaciers contain much more than pure ice. Dust, windblown debris and spillage from nearby landslides is incorporated into the glacier as fresh snow falls on it each winter. The glacier picks up still more debris as it slides downhill.
This acquired material tends to be broken down by the crushing force of the mass of ice until the glacier is rich with fine sediment mixed with ice. When the glacier melts, the water it releases carries much of this debris downhill with it. As the meltwater flows, it loses energy and drops the large stones it carries. Farther downstream, the water flows slowly enough to deposit fine sediment that can build over time to cover a large area. This field of sediment is the glacial outwash plain.Learn more about Earth Science
The three main examples of constructive forces are crustal deformation, volcanic eruptions and deposition of sediment. Constructive forces are the processes that build land formations. These formations include mountains and sedimentary rock layers.Full Answer >
In the field of ecology, a natural system is one that exists in nature, independent of any human involvement. The natural system consists of all the physical and biological materials and their intertwined processesFull Answer >
Earth leakage refers to the unwanted flow of electrical current from the live wire (red wire) to the earth wire (green or yellow wire). It is also referred to in some countries as ground leakage or leakage current.Full Answer >
According to the National Oceanographic and Atmospheric Administration, seafloor spreading is caused by the flow of plastic mantle rock beneath the Earth's oceanic crust. These flows force the seafloor apart, allowing pressurized mantle rock to force its way upward, causing a chain of vents and volcanoes along the mid-ocean ridges. The flow of mantle rock is thought to be responsible for all movement of crustal plates and the resulting interactions.Full Answer >
