Why does molten rock in earth's mantle rise to the lithosphere in a convection current?
Molten rock in the Earth's mantle rises to the lithosphere due to convection currents driven by heat from the Earth's core. As the mantle material heats up, it becomes less dense and rises, while cooler, denser material sinks. This continuous cycle creates a convection current that facilitates the movement of molten rock toward the lithosphere, where it can lead to volcanic activity or contribute to the formation of new crust.
What else can I help you with?
What is the mantles cycle that involves heating rising cooling and sinking?
The mantle cycle you are referring to is known as mantle convection. It involves the movement of hot, less dense mantle material rising towards the Earth's surface, cooling, then sinking back down into the mantle. This process is a driving force behind plate tectonics and the overall dynamics of Earth's lithosphere.
Crust and earths upper mantle makes up what?
it is the lithosphere
What type of stresses broke Earth's lithosphere into plates?
The movement of convection currents in the mantle is believed to have caused the Earth's lithosphere to break into plates. These currents create stress within the lithosphere, leading to the formation of tectonic plates.
What states that the earths lithoshere is broken into huge moving slabs of rock driven by motions in the mantle?
The theory of plate tectonics states that the Earth's lithosphere is divided into several large plates that move over the semi-fluid asthenosphere of the mantle. The motion of these plates is primarily driven by convection currents in the mantle.
What is the irregular section of the lithosphere that floats on earths mantle?
The irregular section of the lithosphere that floats on Earth's mantle is known as the tectonic plates. These plates are composed of the Earth's crust and the uppermost part of the mantle, and they vary in size and shape. The movement of these plates is driven by convection currents in the underlying mantle, leading to geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
Which forces responsible for earths crust and lithosphere floating on the mantle?
convection currents in the upper mantle
Is the heat source for the convection current in the mantle in the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
How convection currents are caused and how they move material in the mantle and lithosphere?
Because the mantle and lithosphere have gases or liquids that circulate
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
Mantle is part of the Earth's lithosphere.
How do convection currents in the mantle effect lithosphere movement?
Convection currents in the mantle drive the movement of tectonic plates on the Earth's surface. As the mantle heats up and rises near mid-ocean ridges, it spreads and pushes the plates apart. When the mantle cools and sinks back down near subduction zones, it pulls the plates back together. This process of convection and plate movement is known as plate tectonics.
Which part of the asthenosphere and lithosphere are parts of Earths?
Both the asthenosphere and lithosphere are part of Earth's upper mantle. The asthenosphere is a semi-fluid layer beneath the lithosphere where convection currents occur, while the lithosphere includes the rigid outer layer of the Earth that consists of the crust and the uppermost part of the mantle.
Does the earths lithosphere include part of the mantle?
Yes it does.
What are the three parts that make up Earths mantle?
mesosphere, asthenosphere, ionosphere
Which process is currently accepted explanation of the movement of drifting continents?
the convection currents in the mantle under the earths curst is moving the broken plates in earths lithosphere causing the plates slide across the lithosphere. this process is called tectonics. (jon lay wrote this,)

What is the term for the circular of material inside earths mantle?
QuestionThe term for the circular movement of material inside earth's mantle is convection current. This current causes the movement of the tectonic plates.
What do geologist call the earths crust and upper mantle?
The lithosphere.
