What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
What is the second thickest layer of earth?
The second thickest layer of the Earth is the mantle, located between the crust and the core. It is composed of solid rock that is divided into the upper mantle and the lower mantle. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive geological processes on the Earth's surface.
Which layer of the earth contains the lower mantle?
The lower mantle is located in the middle layer of the Earth's interior, known as the mantle. The mantle is divided into two main regions: the upper mantle and the lower mantle. The lower mantle is situated beneath the upper mantle and above the outer core.
What is the earth's lower mantle?
The lower mantle of the Earth is the layer directly above the core. It is very dense, hot, and composed of thick rock.
Which layer of the earth is thought to be responsible for continental drift?
simple....the answer is mantle.(: Glad to help!
How is the lower mantle different from the inner core?
The lower mantle is a solid layer located between the upper mantle and the outer core of the Earth, composed mainly of silicate minerals. In contrast, the inner core is a solid sphere composed primarily of iron and nickel at Earth's center due to extreme pressure. The lower mantle is part of the mantle layer, whereas the inner core is part of the core layer of the Earth.
What layer is the largest of the earth?
It is in the mantle, consisting of the upper and lower mantle, which measures about 2855 km. It is situated below the Earth's crust, about 35km from Earth's surface.
What layer is 6000 km in depth?
A depth of 6000 km would be within the lower mantle layer of the Earth. The lower mantle extends from about 660 km to 2900 km below the Earth's surface.
What does the upper mantle and lower mantle form?
The upper mantle and lower mantle together form the Earth's mantle, which is the layer of rock between the Earth's crust and core. This region plays a critical role in plate tectonics and the movement of Earth's lithosphere.
What is the lower layer of the mantle composed of?
The lower layer of the mantle is composed of solid rock that is under high pressure and temperature conditions. This layer is known as the lower mantle and is made up of silicate minerals such as peridotite and olivine. It plays a significant role in Earth's mantle convection and the movement of tectonic plates.
What is is the meaning of Earth's lower mantle?
The lower mantle is the portion of the Earth's mantle layer that extends from a depth of 670 km to 2798 km from the surface. Minerals present in the rock of the upper mantle become unstable at these depths. Little is known about the lower mantle other than that seismic waves indicate it is fairly homogenous in lithology and therefore density.
What is the layer of the earth that lies above the outer core?
The layer of the Earth that lies above the outer core is the mantle. It is a viscous layer composed of silicate rocks and is divided into the upper mantle and the lower mantle. The mantle is responsible for most of the Earth's internal heat and convection currents that drive plate tectonics.
