What two elements is earth's atmosphere mostly made up of?
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%).
What are the two most abundant elements in the solid earth?
The two elements that commonly occur within the earth crust are Oxygen and Silicon.
Which two elements make up center earth?
iron and nickel
What are the two most aboundant elements on Earth?
Nitrogen 78 % Silica in soil
The center of the earth is made up of?
the two different elements that make up the center of the earth are iron and nickel. there have been recent studies that there might be other elements there, but we can not know for sure because there has been no artificial (man - made) objects that have been down there.
The mass of the earth is made up mostly of which two elements?
Oxygen and Hydrogen
What are the two most abundant elements by mass found in the earth's crust?
The two most abundant elements by mass in the earth's crust are oxygen and silicone. The crust of the earth typically runs between 20 and 25 miles deep from the surface.
What are the two most abundant element by mass found in the Earth?
The two most abundant elements by mass in the earth's crust are oxygen and silicone. The crust of the earth typically runs between 20 and 25 miles deep from the surface.
When two elements chemically react the mass of the product is?
When two elements chemically react, the mass of the product is equal to the sum of the two masses of the two elements.
About 75 by mass of Earth's crust is composed of what two elements?
About 75 percent of the weight of the Earth's crust is made up of Oxygen and Silicon. The remaining percentage is composed of Aluminum, Iron, Calcium, Sodium, Potassium, and Magnesium.
What are the two elements that make up 75 percent of the total mass of the crustal rocks of the earth?
Oxygen and silicon.
Anyting that is made on earth is made up of?
A liquid, solid, gas, or plasma. Everything on earth is made of several different elements (such as carbon, nitrogen, hydrogen, etc.) in various combinations and variations and mixtures. These elements all derive from hydrogen and helium from the sun. These two basic elements broke down and aged into the elements that can be found, and are yet to be found, in the periodic table.
What accounts for most of the mass of water?
water is made of two elements oxygen and hydrogen. H2O..being that there are two parts of hydrogen and one part oxygen. then most of the mass of water would be hydrogen.
Compounds are made made of how many elements?
Two or more elements.
Earths magnetic field is not the cause of gravity?
No. Those are two quite different forces. The Earth's gravity is caused by the amount of mass Earth has.No. Those are two quite different forces.

What are the two most abundant elements by mass found in Earth's crust?
The 8 most common elements in Earth's crust (by mass): 46.6% Oxygen (O) 27.7% Silicon (Si) 8.1% Aluminum (Al) 5.0% Iron (Fe) 3.6% Calcium (Ca) 2.8% Sodium (Na) 2.6% Potassium (K) 2.1% Magnesium (Mg) Therefore, the most common metallic elements in the Earth's crust would be Silicon and aluminum. (Note that aluminum is a metal, but silicon is considered to be a metaliod -- not to be confused with Silicone which is a synthetic polymer.)
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
