Scientists know that (at least part of) the Earth's mantle is made up of solid rock because p-waves can be detected going through it. S-waves can only go through solids and are not able to pass through the parts of the mantle that are "molten".

∙ 11y agoWe have directly observed the molten rock, also known as magma, that lies underneath the Earth's crust, because it sometimes rises to the surface in the form of volcanic eruptions.

∙ 9y agoBecause s-waves from earthquakes can travel through the mantle rock. S-waves (i.e. shear waves) cannot travel through liquids or gasses.

Is the earths mantle made of liquid?
No. The Earth's mantle is a ductile solid.
What is earths lithosphere made out of?
it is made out of the outer mantle and the crust.
What are these parts primarily made up of in the earths interior?
they are crust and the mantle and also the core
What is rigid layer of earths surface made up of the crust and a part of the upper mantle?
the Lithosphere or Lithospheric Plates
What kind of landforms are made by volcanoes?
It when plates colliding and making the volcanos also when the earths crust is open and the mantle or lava comes out,
Is the earths mantle made of liquid?
No. The Earth's mantle is a ductile solid.
What is earths lithosphere made out of?
it is made out of the outer mantle and the crust.
What is the earths middle mantle made of?
its three layers of the mantle and the middle mantle is were the asthenoshpere is located also through the mantle there are convection currents
How have scientists determined the composition of the earths mantle?
by studying seismic wave travel times, scientist have determined that the lithosphere, which includes the crust and the top of the upper mantle is made up primaraly of the ingenueos rocks granite, basalt and peridotite
What is 80 percent of Earths volume made up of?
The mantle.
How much of earth mass is made up by the mantle?
The Mantle accounts for about 79% of the earths mass
How does plate tectonics affect the mantle?
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.
What mineral is made when the earths mantle and crust compose into a rock form?
diamond
How do scientists think earths crust moves?
The crustal plates (made mostly of low density granitic rock) float on the mantle (made mostly of high density basaltic rock). Convection cells in the mantle move the floating crustal plates around.
How thick earths mantle?
The mantle is found between the core and the innermost layer of the earth. The mantle is made up of mostly solid rock that is 1,802 miles thick.
What are these parts primarily made up of in the earths interior?
they are crust and the mantle and also the core
Rigid layer of earths surface made up of the crust and a part of the upper mantle?
lithosphere
