What kind of rock is Venus made of?
Venus is made up of a central iorn core and a rocky mantle similar to earth. Venus is made up of a central iorn core and a rocky mantle similar to earth.
What is one large piece of the lithosphere?
its made of mantle and crust
What are some of the differences and similarities between the mantle crust and the core?
Crust- The crust is the thinnest layer of the Earth and is from 0-50 km deep. The crust is not one whole rather it’s separated into different pieces called the plates. The earth’s crust is also the lightest layer, it’s rocky and rigid. Mantle- The mantle of the Earth is the largest and the layer that takes up most of the space-2900 km deep. The mantle is mostly made up of magma and molten rocks because of the heat given off by the core. Core- The core is the hottest, second biggest and inner most layer of the earth. It mainly consists of solid iron and nickel. The heat in the core is what causes the mantle to be in fluid form. The core is really hot heating up from 3500 C to more than 6000 C Compare- The similarities of the three types of layers are- The three layers help to support the structure of the Earth. The mantle and the core are really hot and the two biggest layers. Both the Mantle and crust are solid. Contrast- The difference is that the crust of the earth is made out of soil and rocks while the mantle consists of lava and molten rocks, finally the core is made up of solid iron and nickel. All the layers are made up of different natural materials.
What mineral is common in Earth's mantle?
Olivine is the most common mineral in the Earth's mantle.
What feature of the ocean floor does the center slit stand for?
the mantle
What is the composition of the Earth lower mantle?
•Thet Low•The Lower Mantle is made of Olivine, Pyroxene, and Feldspar.v •The Lower Mantle is made of Olivine, Pyroxene, and Feldspar.er Mantle is made of Olivine, Pyroxene, and Feldspar.
What is the lower mantle made out of?
The earth's lower mantle is composed of an olivine mineral with a perovskite structure.
What is the lower layer of the mantle called?
The mesosphere
What is the earth's lower mantle made of?
The earth's crust lower mantle is made up of silicate perovskites and ferropericlase. While the silicate perovskites are the names given to calcium silicates and magnesium iron, ferropericlase is an oxide of magnesium/iron. The lower mantle is at a depth that ranges from 650 kilometers to 2,890 kilometers.
Is the lower part of the mantle called the lithosphere or asthenosphere?
The lower part of the mantle is actually names the mesosphere. It is overlain by the asthenosphere which is part of the upper mantle and this in turn is overlain by the lithosphere which is made up of the very uppermost mantle and the crust.
What is above the lower mantle?
The middle mantle is just above the lower mantle.
What material is the lower mantle made of?
The earth's lower mantle is composed of an olivine mineral with a perovskite structure.
What is the lower part of the mantle callet?
The Lower Mantle
What contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
What is the lower mantle beneath?
The lower mantle is beneath the crust.
What are the part of the mantle?
The upper mantle and the lower mantle.
What is the Difference between the upper and lower mantle?
Working outwards from the centre: The Earth is believed to be formed of an inner core, outer core, inner mantle, outer mantle, and the crust. The mantle is two thousand miles thick and makes up more than three-quarters of the Earth's volume.
