Subduction is the process where tectonic plates collide, causing one plate to be forced deep into the Earth's mantle. This movement carries sediments and water from the Earth's surface into the mantle. The sediments and water can then influence mantle dynamics and geological processes.

What is a deposition of sediments?

The process of loosening and removing rock and sediments?
This process is called erosion, which involves the wearing away of rock and sediments by natural forces such as water, wind, and ice. Erosion can result in the transport of these materials to new locations, shaping the landscape over time.
What is compaction and cementation?
Compaction does not necessarily cause materials to stick together. Cementation is more like having a binding material between the layers. Even compaction CAN result in binding together of materials such as sandstone.
What is it called when sediments are layered and sorted by size?
It is called stratification - when sediments are deposited in layers based on their size and weight. This process is often driven by water or wind.
The process in which sediments are dropped by wind water ice or gravity?
The process is called deposition, where sediments are deposited or laid down by agents such as wind, water, ice, or gravity. This typically occurs when the energy of the transporting medium decreases, causing the sediment particles to settle out and accumulate in a new location.
Why is water a necessary component of the melting process in subduction zones?
Water plays a crucial role in the melting process at subduction zones by lowering the melting temperature of the Earth's mantle rocks. As the subducting oceanic plate sinks into the mantle, water is released from the subducted crust and sediments, which then infiltrates the mantle wedge above the subducting slab. This water reduces the melting point of the mantle rocks, leading to the formation of magma that rises to the surface and contributes to volcanic activity at subduction zones.
How can floating sediments be removed from water vapor?
Floating sediments can be removed from water vapor using the process of purification. This process is used to create drinking water for every day use.
Why does a floodplain contain fertile soil that is good for growing plants?
because when the water floods it carries the rich sediments of the water floor and brings them to the surface where it deposits
What is the process alluvial deposition?
Alluvial deposition is the process by which sediments carried by flowing water are deposited when the water loses its energy. As the water slows down, it can no longer transport the sediments, causing them to settle and accumulate on the riverbed or floodplain. Over time, these sediments contribute to the formation of alluvial deposits, such as river deltas and alluvial fans.
How do you feel about the water cycle?
Water cycle is a rejuvenating process. It brings rain.
Sediments that settle out during water treatment?
The sediments that settle out during water treatment are typically removed through a process called sedimentation. In this process, water is allowed to stand still in a tank or basin, causing the heavier particles to settle to the bottom. These settled sediments, often referred to as sludge or floc, are then removed from the water through a scraping or draining mechanism.

What is the process that changes a rock into sediments?
Weathering and erosion break down rocks into smaller pieces called sediments. This process can happen through physical weathering (mechanical breakdown) or chemical weathering (decomposition of minerals). The resulting sediments can then be transported by wind, water, or ice to new locations.
What process brings water down on earth?
The process that brings water down on Earth is called precipitation. This occurs when water droplets or ice crystals in clouds become too heavy to remain suspended and fall to the ground as rain, snow, sleet, or hail.
What is the process called that moves water from bodies of water to the atmosphere?
Precipitation brings water from atmosphere to earth's surface. It brings water in the form of snow, sleet, rain and hailstone.
What is the process that carries sediments into rivers?
The process that carries sediments into rivers is called erosion. Erosion occurs when weathering and other factors break down rocks and soil, which are then transported by water, wind, or ice and deposited into rivers.
