How do upper mantle rocks differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
What is the state of matter of the Earth's upper mantle?
The Earth's upper mantle is composed of solid rock that flows through liquid rock, also known as lava.
What are the layers of Earth today?
crust, upper mantle, lower mantle, outter core,inner core,rock
What rock does the upper mantle contain?
The dominant rock type of the upper mantle is peridotite.
What is the Texture of mantle?
the mantle is a hard rock in the upper Mantle and softer lower down.also the texture of it is coarse and solid. the colour of it is an Orange red colour.
What is the plastic like rock of the lower mantle called?
the plasic like rock of the lower mantle is the asthenosphere
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.
Is silica and forms of granite found in upper mantle?
Silica is found in the upper mantle, but not granite. Most of the minerals in the mantle are silicates, meaning they contain silica. Granite is found in the crust, primarily conditnental crust, as it forms from high-silica magma. The upper mantle is composed mostly of a lower-silica rock called peridotite.
What is the layer of softer rock in the upper mantle?
lithosphere
The molten rock that is found in the upper mantle are?
Magma.
