Abundance of Elements

Abundance of elements refers to how common each element is in the universe or Earth's crust. Some elements, like oxygen and silicon, are very abundant because they are major building blocks of planets and life. Others, like gold or platinum, are rare and found in small amounts. This distribution results from processes like cosmic fusion, stellar life cycles, and geological activity over billions of years. Understanding element abundance helps scientists learn how planets form, how materials are distributed in space, and how Earth's resources are composed.
