How are pressure and heat involved in melting rock in the mantle?
Pressure and heat in the mantle cause the rocks to become ductile and start deforming. As pressure decreases and heat increases due to the rising of magma, the rocks reach their melting point, allowing them to melt. This melted rock can then rise to the surface as magma and form igneous rocks.
What are two factors in the mantle that contribute to the rock cycle?
Temperature and pressure are two factors in the mantle that contribute to the rock cycle. Heat from the Earth's interior and pressure from overlying rocks can cause rocks in the mantle to melt, solidify, or undergo metamorphism, leading to the formation of different types of rocks.
Where does heat that changing rocks into metamorphic rock come from?
The heat from the mantle and core.
In the mantle heat is transferred as soft rocks flow slowly in cycles known as?
In the mantle, heat is transferred through convection, where soft rocks flow slowly in cycles known as mantle convection cells. These cells are responsible for the movement of tectonic plates and the transfer of heat from the Earth's interior to the surface.
In the mantle heat is transferred as soft rocks flows in cycles known as?
Convection currents.
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 a concentration of heat in the mantle that produces magma?
Yes, a concentration of heat in the mantle can produce magma through a process called mantle melting. This occurs when temperatures rise sufficiently to melt rock, often due to factors like increased pressure or the presence of water, which lowers the melting point of the rocks. The resulting magma can accumulate and eventually lead to volcanic activity when it rises to the Earth's surface.
What are some examples of rock types?
Igneous rocks - rocks formed from molten rock of the mantle Sedimentary rocks - rocks found in streams Metamorphic rocks - rocks changed by the effects of heat and pressure
Does slow movements of mantle rock called radiation transfer heat in the mantle?
No, slow movements of mantle rock called convection transfer heat in the mantle. Convection occurs due to the heat generated by the radioactive decay of elements in the mantle causing molten rock to rise and cooler rock to sink in a continuous cycle.
How is metamorphic rocks organically made?
rocks pile on other rocks pushing them downward, as they reach about one eighth of the way towards the mantle the pressure and heat make metamorphic rocks
How do the rocks in the mantle move?
The movement of rocks in the mantle is driven by convection currents. Heat from the Earth's core causes the rocks to become less dense, causing them to rise towards the surface. As they cool, they become denser and sink back down, creating a cycle of movement within the mantle.
What does the heat that produces geothermal energy come from?
The heat comes from hot rocks deep under the surface of the earth.
