What elements make up most of the lower mantle?
The most common compound is silicate perovskite, made up of magnesium, iron, silicon and oxygen. The other common main component of the lower mantle is ferropericase, which is made of magnesium, iron and oxygen.
Which layer makes up the mantle?
The mantle is composed of the mesosphere and the asthenosphere and the uppermost part of the mantle. That uppermost part of the mantle is what is combined with the crust to make the lithosphere.
What element make up most of the mantle shade only 4?
The major elements that make up the mantle are oxygen, silicon and magnesium.
What is the most abundant element in the earth’s crust?
Oxygen
Q: What is the most abundant element on Earth? A: Oxygen, which composes about 49.5\% of the total mass of the Earth’s crust, waters and atmosphere, according to the textbook “Modern Chemistry.” Silicon is second at 28\%.
What’s the mantle made of?
silicate rocks
Earth’s mantle is our planet’s thickest layer and is a mostly-solid layer that lies between the crust and core. It can be found about 1,800 miles (2,890 km) deep and is composed mostly of silicate rocks rich in oxygen, magnesium, aluminum and silicon.

What is the most abundant element in the core?
Iron
Iron is the most abundant element, by mass, in the Earth, constituting about 80\% of the inner and outer cores of Earth. The molten outer core is about 8000 km in diameter, and the solid inner core is about 2400 km in diameter.
Is the mantle made of magma?
Much of the planet’s mantle consists of magma. Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur. The high temperatures and pressure under Earth’s crust keep magma in its fluid state.
What is the most abundant element in the atmosphere?
Nitrogen
Gases. The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78\% of air. Oxygen (O2) is the second most abundant gas at about 21\%. The inert gas Argon (Ar) is the third most abundant gas at .
What are the 5 most important elements?
1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.
What is the most common element in the atmosphere?
What are facts about the mantle?
The mantle is a layer between the crust and the outer core. Earth’s mantle is a silicate rocky shell with an average thickness of 2,886 kilometres (1,793 mi). The mantle makes up about 84\% of Earth’s volume. It is predominantly solid but in geological time it behaves as a viscous fluid.
What is the Earth’s mantle made of?
The best description of Earth’s mantle is it is made up of rock so hot that it flows. This layer is also called the asthenosphere. This Earth’s mantle has a thickness that reaches 2,900 kilometers to wrap up the Earth’s core. It is a rocky layer that covers 84\% of Earth’s volume.
What material is the upper mantle made of?
The upper mantle is made up of rock, which is very similar to the Earth’s crust. The rock in the upper mantle tends to have more magnesium, as opposed to rocks in the crust that have more silicon and aluminum.
What are some interesting facts about the Earth’s mantle?
6 Fascinating Facts About the Earth’s Mantle Earth has the same recipe of elements as the Sun and the other planets (ignoring hydrogen and helium, which have escaped Earth’s gravity). The top part of the mantle is slowly stirred by the plate motions occurring above it. This is caused by two types of activity. Our most powerful technique for exploring the mantle is monitoring seismic waves from the world’s earthquakes.
