What else can I help you with?
mantle is composed of these rocks?
ferro magnesium silicate rocks
What are rocks that come from the mantle?
Rocks that come from the mantle are called mantle rocks. These rocks are typically formed deep within the Earth's mantle and can include peridotite, dunite, and eclogite. Mantle rocks are brought to the surface through processes like volcanic eruptions or tectonic movements.
The flotational balance achieved between rocks of the crust lithosphere and deeper mantle is called?
Isostasy is the flotational balance achieved between rocks of the crust lithosphere and deeper mantle. This balance is maintained as lighter rocks of the crust "float" on the denser rocks of the mantle below.
How is the reservoir of molten rocks called?
The Mantle.
Magma forms when rocks begin to melt?
Yes. Magma is underground molten rock.
What is the area between the mantle and core where hot rocks forced into the crust?
The area is known as the mantle transition zone and it is located between the upper mantle and the lower mantle. This region is characterized by high pressures and temperatures, causing rocks to undergo changes in their physical and chemical properties.
What happens to the rocks in the mantle?
the minerals posses a number of properties that are used as an aid in their identitification
What forms earth crust?
thickness 1/8( a mixture of lighter and heavier rocks which were forced out from the mantle by volcanic activity)
How do upper mantle rock differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
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
What a Mantle?
A mantle is a layer of hot rocks.
What are rocks that come from the mantle called?
Igneous rock.
What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
mantle is composed of these rocks?
ferro magnesium silicate rocks
What it the Mantle made of?
the mantle is made of hot lava with rocks and pee
What are rocks that come from the mantle?
Rocks that come from the mantle are called mantle rocks. These rocks are typically formed deep within the Earth's mantle and can include peridotite, dunite, and eclogite. Mantle rocks are brought to the surface through processes like volcanic eruptions or tectonic movements.
WHAT ARE Mantle rocks classified as?
Mantle rock is classified as ultramafic igneous rock.
