Coal extraction involves using machinery such as excavators, draglines, or continuous miners to remove the coal from the lithosphere. The process typically involves drilling into the ground to access the coal seam, then using heavy equipment to remove the overlying rock and expose the coal. Finally, the coal is extracted and transported to the surface for processing.
What else can I help you with?
Does the oceanic lithosphere get older or younger?
Oceanic lithosphere gets older as it moves away from the mid-ocean ridges where new lithosphere is formed. This process, known as seafloor spreading, causes older lithosphere to be pushed further from the ridge, resulting in a gradient of lithosphere age with the oldest being farthest from the ridges.
Where does recycling lithosphere take place?
Recycling of lithosphere primarily takes place at convergent plate boundaries, where oceanic lithosphere is subducted beneath continental lithosphere and melted back into the mantle. This process helps regulate the movement of tectonic plates and influences the formation of volcanic arcs and mountain ranges.
Which is thicker the earth's crust or the lithosphere?
The lithosphere is thicker than the Earth's crust. The lithosphere includes the crust and the upper part of the mantle, typically ranging in thickness from about 100 to 200 kilometers beneath the oceanic crust and up to 250 kilometers beneath continental crust.
What is the process by which new oceanic lithosphere is created as older materials are pulled away?
This process is called seafloor spreading. It occurs at mid-ocean ridges where tectonic plates move apart, allowing magma to rise from the mantle and solidify as new oceanic lithosphere. As the plates continue to separate, the new lithosphere gets pushed away from the ridge, creating a continuous cycle of formation and movement.
Where does the old lithosphere go when it is recycled?
Old lithosphere is recycled back into the Earth's mantle through the process of subduction. As tectonic plates converge, one plate is forced beneath the other and descends into the mantle along a subduction zone. This process allows the old lithosphere to be recycled and remelted into the mantle, contributing to the movements and dynamics of Earth's tectonic plates.
Why is it so difficult to extract iron from is ore?
Extracting iron from its ore, such as hematite or magnetite, is a complex process because it involves multiple steps. The iron ore must first be crushed and concentrated, then undergo processes like smelting to extract the pure iron. These processes require high temperatures, specific chemical reactions, and advanced machinery, making it a challenging and energy-intensive process.
What does oil do in the process of lubricating machinery?
Oil in the process of lubricating machinery reduces friction between moving parts, which helps prevent wear and tear, reduces heat generation, and prolongs the lifespan of the machinery.
What process is used to extract a aluminum?
Electrolysis
What is the process used to extract titanium?
Reduction
How can I convert all grain to extract in my brewing process?
To convert all grain to extract in your brewing process, you can use a method called "mashing." This involves soaking the crushed grains in hot water to extract sugars, then straining the liquid to create a concentrated extract. This extract can then be used in place of the grains in your brewing recipe.
How do you use word extract in a sentence?
The process used to extract oil from the oil sands in northern Canada is very costly. - Extract is a verb that means "To remove or take out by special means or by force." I use vanilla and orange extract when I bake a cake. - Extract is a noun: To withdraw (as a juice or fraction) by physical or chemical process
Does the oceanic lithosphere get older or younger?
Oceanic lithosphere gets older as it moves away from the mid-ocean ridges where new lithosphere is formed. This process, known as seafloor spreading, causes older lithosphere to be pushed further from the ridge, resulting in a gradient of lithosphere age with the oldest being farthest from the ridges.
The main process by which heat flows upward through the lithosphere is?
The main process by which heat flows upward through the lithosphere is conduction. Heat is transferred through the solid rock by the vibration of atoms and the transfer of energy between neighboring particles. Convection also plays a role in heat transfer within the Earth's mantle, but conduction is the dominant process in the lithosphere.
What is orogenesse?
Assuming that you are referring to orogenesis,it is the process of tectonic movements in Earth's lithosphere.
What is the function of the intestin in an earthworm?
To process food and extract nutrients.
Describe the process of subduction and how density plays a role in this process?
Ocean lithosphere is higher density so it sinks to the bottom.
Where does recycling lithosphere take place?
Recycling of lithosphere primarily takes place at convergent plate boundaries, where oceanic lithosphere is subducted beneath continental lithosphere and melted back into the mantle. This process helps regulate the movement of tectonic plates and influences the formation of volcanic arcs and mountain ranges.
