What else can I help you with?
The driving forces to tectonic plates are related to convection currents in earths what?
mantle.
What is decompression melting how it relates to Earths internal convection?
Decompression melting occurs when a decrease in pressure on a mantle rock causes it to melt without an increase in temperature. This process is related to Earth's internal convection because rising mantle material undergoes decompression as it moves towards the surface, leading to melting and the formation of magma chambers.
What components are least likely found in the earths mantle?
High concentrations of water, carbon dioxide, and other volatile elements are least likely found in the Earth's mantle due to its high pressure and temperature conditions, which tend to drive these volatile components to the Earth's surface and atmosphere.
How many layers in earths mantle?
The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.
All what are conditions in which the mantle will melt and liquefy except?
The mantle will melt and liquefy under conditions of increased temperature, decreased pressure, or the addition of water (flux melting). However, melting does not occur simply due to an increase in pressure alone, as higher pressure typically raises the melting point of mantle materials, preventing them from liquefying. Thus, while temperature and water can induce melting, pressure alone does not lead to mantle liquefaction.
Which combination of temperature and pressure is inferred to occur whitin earths stiffer mantle?
High temperature and high pressure are inferred to occur within Earth's stiffer mantle. As depth increases in the mantle, both temperature and pressure increase. This combination of high temperature and pressure allows for the solid rock to exhibit ductile behavior, resulting in the flow of solid material over long periods of time.
When rocks return to earths mantle to earths mantle they can eventually melt and become magma. and are the main factors that control this change.?
heat and pressure
Is the earths lower mantle hot?
the average temperature for the Earth's lower mantle is 5400 degrees
Which layer of the Earths atmosphere is the pressure inferred to be 1.0 million atmospheres?
Stiffer mantle.
The driving forces to tectonic plates are related to convection currents in earths what?
mantle.
What is decompression melting how it relates to Earths internal convection?
Decompression melting occurs when a decrease in pressure on a mantle rock causes it to melt without an increase in temperature. This process is related to Earth's internal convection because rising mantle material undergoes decompression as it moves towards the surface, leading to melting and the formation of magma chambers.
Why do few earthquake happen in earths mantle?
Few earthquakes happen in the earths mantle do to the fact that the mantle has a folded deformation. This means that the amount of pressure on the mantle caused it to deform.
Why isn't the earths entire mantle liquid?
The Earth's mantle is not entirely liquid because of the high pressure and temperature gradients that exist within it. While parts of the mantle can be semi-molten or partially melted, most of it remains solid due to the immense pressure acting on the rock materials. The solid regions allow for the transmission of seismic waves and support the tectonic plates that make up the Earth's crust.
Which temperature is inferred to exist within Earths plastic mantle?
2000 celcius
How does pressure determine whether the mantle is solid or liquid?
The melting temperature of materials is affected by their confining pressure. The higher the pressure the higher the melting temperature. As such as you move deeper into the mantle, the tempraeture will increase, but because of the overlying material so to will the confining pressure which drives up the melting temperature. When high temperature mantle material moves nearer to the surface such as near a mid-ocean-ridge the confining pressure falls faster than the materials temperature and this can cause the melting point to drop below the temperature of the material leading to melting.
What is the range temperature within the stiffer mantle?
The temperature range within the stiffer mantle is between 500 and 900 degrees Celsius. This region is known as the upper mantle and is composed of solid rock that can deform under high pressure and temperature.
What components are least likely found in the earths mantle?
High concentrations of water, carbon dioxide, and other volatile elements are least likely found in the Earth's mantle due to its high pressure and temperature conditions, which tend to drive these volatile components to the Earth's surface and atmosphere.
