What are the three most abundant elements found in earth`s crust that combine to form minerals?

• Correct answer is oxygen, silicon, aluminium. 
• Earth's Crust Elements. The crust is a rigid surface containing both the oceans and landmasses. ...
• #1: Oxygen. Oxygen is by far the most abundant element in the Earth's crust, making up 46% of mass—coming up just short of half of the total. ...
• #2: Aluminium: Aluminum is the third most common element in the Earth’s crust.

Because of its strong affinity for oxygen, aluminum is rarely found in its elemental state. Aluminum oxide (Al2O3), aluminum hydroxide (Al(OH)3) and potassium aluminum sulphate (KAl(SO4)2) are common aluminum compounds.

Aluminum and aluminum alloys have a variety of uses, from kitchen foil to rocket manufacturing.

• #3: Silicon: More than 90% of the Earth’s crust is composed of silicate minerals, making silicon the second most abundant element in the Earth’s crust.

Silicon links up with oxygen to form the most common minerals on Earth. For example, in most places, sand primarily consists of silica (silicon dioxide) usually in the form of quartz. Silicon is an essential semiconductor, used in manufacturing electronics and computer chips.
