Q:

What is the moon made of?

A:

Quick Answer

The lunar crust is made of 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, 3 percent calcium and 3 percent aluminum. The moon's core is thought to consist of iron, sulfur and nickel, with the largest middle layer, or mantle, composed of olivine, clinopyroxene and orthopyroxene.

Full Answer

The moon’s core occupies about 2 percent of the moon’s entire mass and is in a partly molten state. The moon’s surface layer also has trace amounts of 0.42 percent chromium, 0.18 percent titanium, 0.12 percent manganese, potassium, uranium, thorium, hydrogen and a few more elements. All these elements form a strong layer called regolith. Mafic plutonic and maria basalt are the two types of rocks found in the regolith.

    What is the Earth's lower mantle made of?

    A:

    Earth's lower mantle is made up of mantle-crust that consists of aluminum, silicon, magnesium, calcium, oxygen and iron. These elements in the lower mantle account for 72.9 percent of the entire mass of the Earth's mantle and about 50 percent of the planets entire mass. The lower mantle is directly underneath Earth's upper mantle and stretches from 416.319 to 1809.976 miles below the surface.

  • Q:

    What elements make up Earth's crust?

    A:

    Elements that make up Earth's crust include silicon, aluminum, iron, calcium, sodium and magnesium. Oxygen is also present and bonds with these other elements to create oxides. Oxygen is the most abundant element in the crust, followed by silicon. These elements form rocks and minerals.

    Which layer of the Earth has the greatest mass?

    A:

    The layer on Earth with the most mass in the mantle, which is made up of silicate compounds, iron, silicon, magnesium, oxygen and aluminum. The mantle is a solid mass that generates heat reaching over 1,832 degrees Fahrenheit, which causes it to melt in a way similar to plastic.

  • Q:

    What are the five elements found in nature?

    A:

    The five most abundant elements in the Earth's crust are oxygen, silicon, aluminum, iron and calcium, in that order. Sodium, potassium and magnesium are also prevalent in the Earth's crust. Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur are abundant elements in biological systems, commonly referenced using the memory device CHNOPS. Air is made mostly of oxygen and nitrogen with small amounts of other gaseous elements, such as carbon dioxide.
