What are these parts primarily made up of in the earths interior?
they are crust and the mantle and also the core
What is the lower crust made up of?
The lower crust is primarily made up of igneous rocks such as gabbro and basalt. It is denser and more mafic (rich in magnesium and iron) compared to the upper crust. The lower crust is also hotter and more ductile than the upper crust.
Percent of Earth's crust is made up of magnesium using volume?
Magnesium makes up about 2% of the Earth's crust by volume. It is the eighth most abundant element in the Earth's crust.
What layer is made of magnesium and smaller amounts of aluminum and silicon?
earths mantle is made of silicon,iron,aluminum,calcium,sodium,potassium,magnesium,and mostly oxygen
Is the moon composition similar to the composition of the Earth's crust?
The moon's crust composition is similar to the Earth's, but the moon's mantle contains a higher amount of iron. While the moon's crust is composed of 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, and trace amounts of other elements. The Earth's crust is made up of 46.6 percent oxygen, 27.7 percent silicon, 8.1 percent aluminum, 5.1 percent of iron, 2.1 percent magnesium, and other elements.
What percent of Earths crust do silicates make up?
Silicates make up about 90% of Earth's crust. These minerals are composed of silicon and oxygen, along with other elements like aluminum, iron, calcium, and magnesium. Silicate minerals are the building blocks of most rocks on Earth's surface.
