Elements and compounds in the Earth's crust are extracted through various methods, primarily mining and quarrying. Mining involves the removal of minerals from underground deposits, often using techniques like open-pit or underground mining, depending on the depth and location of the resource. Quarrying, on the other hand, is used for extracting stone and other materials from surface deposits. Once extracted, these materials undergo processing to separate the desired elements and compounds for use in various applications.

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.
Why is iron found as a compound in the earths crust?
Iron is found as a compound in the Earth's crust primarily due to its high reactivity, which leads it to combine with other elements, such as oxygen and sulfur, to form minerals like hematite and magnetite. These compounds are stable and form during geological processes, including oxidation and sedimentation. Additionally, iron is one of the most abundant elements in the universe, and its compounds are integral to various geological formations and processes.
What are the three most common elements in Earths continental crust and oceanic crust?
The three most common elements in Earth's continental crust are oxygen, silicon, and aluminum. In the oceanic crust, the predominant elements are oxygen, silicon, and magnesium. While oxygen and silicon are abundant in both types of crust, aluminum is more prevalent in the continental crust, whereas magnesium is more common in the oceanic crust.

Oxygen is a gas at normal conditions. Scientists report that oxygen is the most common element in the earths crust. The earths crust is composed of solids and liquids. Explain this apparent contradi?
If you talk about elements, then oxygen is O, and O is found in many, many COMPOUNDS. So, if a compound is found in the crust, and if it contains oxygen (like water, H2O), then the element oxygen will be counted. It doesn't have to be in a gaseous form. In addition, O2 gas can also be found dissolved in some liquids.
