Cool regions of the mantle are typically found near the Earth's surface, while hot regions are deeper within the mantle. The boundary between the two is known as the lithosphere-asthenosphere boundary, which separates the cooler, rigid lithosphere from the hotter, more ductile asthenosphere.

Where is Convection occurring in the mantle?
Convection in the mantle occurs in the asthenosphere, which is a semi-fluid layer located just below the lithosphere. Heat from the Earth's core causes hot material in the mantle to rise, cool, and then sink back down in a continuous cycle, driving plate tectonics and geological processes on the Earth's surface.
What is the area between the mantle and core where hot rocks forced into the crust?
The area is known as the mantle transition zone and it is located between the upper mantle and the lower mantle. This region is characterized by high pressures and temperatures, causing rocks to undergo changes in their physical and chemical properties.
What layer of the earth is hot and semisolid?
The layer of the Earth that is hot and semi-solid is the mantle. The mantle is located between the Earth's crust and core and is made up of molten rock, called magma, that circulates due to heat convection from the Earth's core.
What is the composition and approximate thickness of the mantle?
The mantle is composed primarily of silicate minerals rich in magnesium and iron. It is approximately 2,900 kilometers thick and is located between the Earth's crust and the core.
What best describes the mantle?
The mantle is the layer of the Earth located between the crust and the core. It is composed of hot, solid rock that is capable of flowing slowly over long periods of time. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive plate tectonics.
What regions was the result of plumes of hot mantle rising in a hot spot within a plate?
the islands of hawaii
A very long lived magma source located deep in the mantle is called?
A mantle plume. These plumes are thought to be responsible for hotspot volcanism, where magma erupts through the Earth's crust in localized regions, such as the Hawaiian Islands. The source of mantle plumes is still debated among geologists.
How do currents in the mantle transfer heat?
hot stuff rises, cool stuff sinks
Where is the mantle hot spot?
The mantle hot spot is located beneath the Earth's lithosphere, usually at the boundary between the mantle and the core. Hot spots are areas where magma from the mantle rises and generates volcanic activity on the Earth's surface. Examples of hot spots include Hawaii and Yellowstone.
Where is Convection occurring in the mantle?
Convection in the mantle occurs in the asthenosphere, which is a semi-fluid layer located just below the lithosphere. Heat from the Earth's core causes hot material in the mantle to rise, cool, and then sink back down in a continuous cycle, driving plate tectonics and geological processes on the Earth's surface.
How can mantle flow because its made of hot liquid magma?
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.
What are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
What is the circulation within earths mantle called?
The circulation within Earth's mantle is called mantle convection. This process involves the movement of hot material rising and cool material sinking in the mantle, creating convection currents that drive plate tectonics.
What is the area between the mantle and core where hot rocks forced into the crust?
The area is known as the mantle transition zone and it is located between the upper mantle and the lower mantle. This region is characterized by high pressures and temperatures, causing rocks to undergo changes in their physical and chemical properties.
What is the layer of the earth above the core called?
The layer of the Earth above the core is called the mantle. It is located between the core and the Earth's crust. The mantle is composed of hot, semi-solid rock.
What layer of the earth is hot and semisolid?
The layer of the Earth that is hot and semi-solid is the mantle. The mantle is located between the Earth's crust and core and is made up of molten rock, called magma, that circulates due to heat convection from the Earth's core.
What a Mantle?
A mantle is a layer of hot rocks.
