To start off, Silicon and oxygen are among the most abundant elements in the universe: oxygen is the third most common element and silicon is the seventh. They readily combine to form silicon dioxide (silica), making it one of the most common solid materials in the universe. Additionally, silica is less dense than many other abundant substances within Earth. Therefore when Earth formed, the more silica-rich materials tended to float toward the surface.
What else can I help you with?
What is the comostion of the earths crust?
Mostly iron, oxygen, silicon, magnesium, sulfur, nickel, and calcium.
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.
What elements are found in the earths crust and has 14 protons?
Silicon is the element in the Earth's crust that has 14 protons. Quartz is crystallized Silicon Dioxide. Flint is also silicon dioxide. The compounds of Silicon are known as silicates.
What is the mass of the earth is made by which two elements?
In the Earth crust the most abundant are oxygen and silicon.
What happens when earths two most abundant elements are combined?
The two most abundant elements in the Earth's crust are oxygen and silicon. When you combine them, you get silicon dioxide; which depending on the exact form it takes is glass or quartz or sand.They tend to combine further with other elements to produce silicate rocks.The two most abundant elements in Earth as a whole are iron and oxygen. When you combine them, you get iron oxide (rust, hematite, magnetite). The reason iron isn't more common in the crust than it is is that it's heavy and has been concentrated in the Earth's core.
What are the two most common elements in the earths crust?
One is silicon, but I don't know the other:(oxygen
Identify the two most abundant elements in the earths crust?

Which two elements are the most abundant in the earths crust?
Oxygen and silicon are the two most abundant elements in the Earth's crust. They make up about 75% of the Earth's crust by weight.
What elements are found in a high proportion in Earths crust?
The Elements found in a high proportion in the Earths crust are, 1. Oxygen. 2. Silicon. 3. Aluminum. 4. Iron. 5. Calcium. 6. Sodium. 7. Potassium. 8. Magnesium.
What three elements make up earths crust?
The three main elements that make up Earth's crust are oxygen, silicon, and aluminum. These elements combine to form the most abundant minerals found in the Earth's crust, such as quartz (silicon dioxide) and feldspar (aluminum silicates).
What are the two most abundant elements in earths crust and what mineral group do these elements form?
oxygen and silicon they form silicates, i think
