High temperature and pressure in the mantle cause the rock to become more fluid-like. This allows it to flow slowly over geological timescales, contributing to the movement of tectonic plates. Additionally, the presence of partial melting can further decrease the viscosity of the rock, increasing its fluidity.
What else can I help you with?
What is the plastic like rock of the lower mantle called?
the plasic like rock of the lower mantle is the asthenosphere
Which layer makes up 2-3 of the earth's mass?
The mantle makes up about 84% of the Earth's mass. It is located between the crust and the core, consisting of mostly solid rock with some semi-fluid or plastic regions. The mantle's thickness is about 2,900 kilometers.
What rock makes up the crust and upper mantle?
The predominant rock in the Earth's crust and upper mantle is called silicate rock, composed mainly of silicon and oxygen. This type of rock is known as "peridotite" in the mantle and "granite" in the crust.
What makes a rock more rigid in the mantle?
The rigidity of a rock in the mantle is influenced by factors such as temperature, pressure, mineral composition, and presence of fluids. Higher temperatures and pressures tend to decrease rigidity, while the presence of minerals like olivine can increase rigidity. The absence of fluids can also contribute to rigidity in the mantle.
Most of Earth's volume is contained in the?
Most of Earth's volume is contained in the mantle, which is the layer between the crust and the core. The mantle makes up about 84% of Earth's volume and is composed of solid rock that can flow slowly over long periods of time.
What is the plastic like rock of the lower mantle called?
the plasic like rock of the lower mantle is the asthenosphere
What is the name of the rock that makes up Mars' mantle?
The mantle of Mars is probably made of peridotite, like Earth's mantle.
Which layer makes up 2-3 of the earth's mass?
The mantle makes up about 84% of the Earth's mass. It is located between the crust and the core, consisting of mostly solid rock with some semi-fluid or plastic regions. The mantle's thickness is about 2,900 kilometers.
What is the fluid in the mantle of the earth?
There is no "fluid"per se in the mantle of the earth. The temperatures at the interface of the mantle and the core are very high, but the pressure prevents melting of the rock. It is quite plastic (can be "shaped" or "formed"), but is solid. Some molten rock can move up through cracks and fissures in the mantle and form pockets. It can even break through the crust to give us volcanic action. Use the link below for more information.
What rock makes up the crust and upper mantle?
The predominant rock in the Earth's crust and upper mantle is called silicate rock, composed mainly of silicon and oxygen. This type of rock is known as "peridotite" in the mantle and "granite" in the crust.
Would plate tectonics work if the mantle were made out of normal solid rock?
No, plate tectonics would not work with a solid rock mantle. The movement of tectonic plates is driven by the flow of semi-fluid rock in the mantle. If the mantle were solid, there would be insufficient convection currents to drive plate movement.
What makes a rock more rigid in the mantle?
The rigidity of a rock in the mantle is influenced by factors such as temperature, pressure, mineral composition, and presence of fluids. Higher temperatures and pressures tend to decrease rigidity, while the presence of minerals like olivine can increase rigidity. The absence of fluids can also contribute to rigidity in the mantle.
What is the plastic-like part of the mantle?
The plastic-like part of the mantle is known as the asthenosphere. It is a semi-fluid layer located beneath the lithosphere, composed of partially molten rock material that allows for the movement of tectonic plates.
How does the addition to fluid relate to the formation of magma?
When the fluids enter the already hot mantle rock, the melting temperature of the hot rock decreases. As a result, the rock begins to melt.
Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
Most of Earth's volume is contained in the?
Most of Earth's volume is contained in the mantle, which is the layer between the crust and the core. The mantle makes up about 84% of Earth's volume and is composed of solid rock that can flow slowly over long periods of time.
Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?
The asthenosphere contains partly melted rock from the upper part of the mantle, while the lithosphere is a rigid layer of the Earth's crust and upper mantle that does not contain melted rock. The asthenosphere's semi-fluid behavior allows tectonic plates to move across it.
