The crust is the uppermost part of the earth. It is also the coolest and least dense. While the mantle is a warmer and dense. The mantle is made up of the Asthenosphere and the Lithosphere. The lithosphere floats in many plates on top of the taffy-like asthenosphere. The Lithosphere is made up of the upper part of the mantle and the crust.

∙ 14y agoThe crust is just the outer layer (that we walk on). The mantle inclues the astenosphere, lithosphere, and upper mantle. The crust is also made of rock, while the mantle has liquid, molten, and solid material.

∙ 15y agoThe crust is divided up into the continental and the oceanic. The latter is 5 km thick and is primarily composed of gabbro, basalt, and diabase. The former is 30-50 km thick and is primiarily composed of granite. It is less dense than the oceanic crust. As one goes further down into the Earth, you have an increase in iron and a decrease in silicon and aluminum. The mantle is approx. 2970 km thick and is divided into the upper and lower. It comprises 84 percent of the Earth's total volume.

∙ 10y agoThe divide between the crust and the mantle is based on the composition of the rocks. The igneous rocks of the crust are of a mafic to felsic (low silica to high silica) composition, with oceanic crust dominated by basalt and contintental rock dominated by granitic rock. The mantle consists of ultramafic (very low silica) rock, with the upper portion consisting largely of a rock called peridodite.

Below earths crust is a layer called the mantle which material will most likely be found in the mantle?
Ultramafic igneous rock.
What is the thick rocky layer around earths core?
The core of the earth is surrounded by the mantle.The earth's core is called the inner core. Just outside that is the outer core, and it is liquid. Outside the liquid outer core is the mantle.
What are tectonic made of Magma and solid mantle crust and magma crust and solid mantle solid rock and molten rock?
Igneous rock
What is a melted rock that can ooze out from below the earths surface through a crack in the crust is called a?
it is just called molten rock, and it comes out of the Earths crust via volcanoes. you can also say that its melted lava
What happens to mantle rock descending oceanic crust scrapes past continental crust?
The mantle rock descending from the oceanic crust causes the water in oceanic crust to be released. This lowers the melting point of the rock and causes it to melt.
What is the layer of the rock beneath the earths crust?
mantle
The layer of rock between earths crust and core?
its called the mantle
What mineral is made when the earths mantle and crust compose into a rock form?
diamond
What has to happen before rock from the earths mantle becomes new piece of crust?
It has to harden
What is the process of recycling materials that make up the earths crust and mantle?
The Rock Cycle ^_^
Below earths crust is a layer called the mantle which material will most likely be found in the mantle?
Ultramafic igneous rock.
What are three words that describe earths mantle?
It's only soft and plastic in that it is not as hard as the brittle rock of the crust and uppermost mantle.
What is the thick rocky layer around earths core?
The core of the earth is surrounded by the mantle.The earth's core is called the inner core. Just outside that is the outer core, and it is liquid. Outside the liquid outer core is the mantle.
What is the hardest layer in the Earth?
well, the earths crust is the hardest cause its made of rock and metal formed together.
What are tectonic made of Magma and solid mantle crust and magma crust and solid mantle solid rock and molten rock?
Igneous rock
What is a melted rock that can ooze out from below the earths surface through a crack in the crust is called a?
it is just called molten rock, and it comes out of the Earths crust via volcanoes. you can also say that its melted lava
What layer is the layer of rock between the earths crust and core?
There are several layers between the outer core and the crust mainly combined into one and called the Mantle.
