Why are silicon and oxygen the main elements in the Earth's crust?
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 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.
