The crust
Silicon is not converted to magnesium in earth; some artificial isotopes of silicon decay to magnesium isotopes.
The dense rock made of magnesium, aluminum, and silicon is likely representative of the Earth's mantle, particularly the upper mantle. Studying this rock can provide insights into the composition, temperature, and dynamics of the mantle, as well as the processes that drive plate tectonics and volcanic activity. Additionally, it can help scientists understand the mineralogical transitions that occur between the crust and the mantle.
The four elements that make up 95 percent of the Earth's mass are oxygen, silicon, iron, and magnesium. These elements are abundant in the Earth's crust and core, contributing to its overall composition.
earths mantle is made of silicon,iron,aluminum,calcium,sodium,potassium,magnesium,and mostly oxygen
The Earth's crust contains oxygen, silicon, aluminum, calcium, iron, sodium, potassium, and magnesium. These elements are the major components of the minerals that make up the Earth's outermost layer.
iron in the core,the mantle is a mix of magnesium, silicon, iron, and oxygen.
The largest layer of Earth's surface that is composed mostly of silicon, oxygen, magnesium, and iron is the mantle. The mantle is located between the Earth's crust and core and makes up about 84% of Earth's volume.

90% is a combo of Iron, Oxygen, Silicon and Magnesium. Order of decreasing percentile
The eight most common elements in Earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. They make up the majority of the minerals and rocks found on the Earth's surface.
