What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
Which components are much more abundant in mantle rocks than crustal rocks?
Mantle rocks are typically richer in magnesium and iron compared to crustal rocks. They also tend to contain higher concentrations of elements like silicon, calcium, and aluminum. Additionally, mantle rocks often have a higher density than crustal rocks due to their mineral composition.
What Crustal rocks are made up primarily?
Crustal rocks are primarily made up of silicate minerals such as feldspar, quartz, and mica. These rocks include granite, basalt, and gneiss, and are commonly found in the Earth's crust.
What are denser crustal rocks or mantle?
Mantle rocks are denser than crustal rocks. The mantle is composed of ultramafic rocks such as peridotite, which have higher densities compared to the mostly granitic rocks found in the Earth's crust. This difference in density plays a key role in the movement and dynamics of tectonic plates on the Earth's surface.
What is crustal material called?
Crustal material is called rock. Rocks are composed of different minerals and can be classified into three main types based on how they are formed: igneous, sedimentary, and metamorphic. These rocks make up the outermost layer of the Earth's crust.
What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
What density of the moon is comparable to that of mantle rocks on?
The mean density of the Moon is around 3.34 g/cm³, which is similar to the densities of mantle rocks found on Earth. The Moon's composition is primarily made up of silicate rocks similar to those found in the Earth's mantle, which contributes to its comparable density.
What Moon rocks have characteristics similar to?
Moon rocks have characteristics similar to basalt and anorthosite found on Earth. Basalts from the Moon display similar mineral compositions to volcanic rocks on Earth, suggesting similar volcanic processes. Additionally, anorthosite, which is rich in the mineral plagioclase, resembles some ancient crustal rocks on Earth, indicating a shared history of planetary formation and differentiation. Overall, the study of Moon rocks provides insights into both lunar geology and the early history of terrestrial planets.

What are the two elements that make up 75 percent of the total mass of the crustal rocks of the earth?
Oxygen and silicon are the two elements that make up 75 percent of the total mass of the crustal rocks on Earth.
Where are fault block mountains most common?
in places where earth crustal rocks are weak.
What are denser crustal rocks or mantle?
Mantle rocks are denser than crustal rocks. The mantle is composed of ultramafic rocks such as peridotite, which have higher densities compared to the mostly granitic rocks found in the Earth's crust. This difference in density plays a key role in the movement and dynamics of tectonic plates on the Earth's surface.
Is gravitational attraction varies directly with tilt of the earth axis?
No the Earth's gravitational attraction is caused by its mass. It varies slightly because the Earth is an oblate spheroid not a sphere, and as a result of variation in the density of crustal rocks. The tilt of Earth's axis has no affect on gravitational attraction.

Are rocks opaque?
Yes. Rocks on the moon are similar to volcanic rocks on Earth.
How did density affect the formation of earth's layers?
As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.
