Question

By mass, which element makes up 26 per cent of the Earth's crust?

Answer 1

The element that makes up 26 per cent of the Earth's crust by mass is silicon. It is the second most abundant element in the Earth's crust after oxygen. Silicon is widely used in industries such as electronics, construction, and healthcare.

Answer 2

By mass, the element that makes up 26% of the Earth's crust is oxygen. Oxygen is the most abundant element on Earth, making up roughly 46% of the Earth's crust by mass. It is essential for life on the planet, and is found in air, water, and rocks.

Answer 3

By mass, the element that makes up approximately 26% of the Earth's crust is silicon. Silicon is a chemical element with the symbol Si and is the second most abundant element in the Earth's crust after oxygen. It is a major component of many minerals, particularly silicates, which are the most common type of minerals found in the Earth's crust.

Answer 4

By mass, the element that makes up approximately 26% of the Earth's crust is aluminum (Al). It's one of the most abundant elements in the Earth's solid outer layer and plays a significant role in various geological and industrial processes.

Answer 5

By mass, the element that makes up about 26 percent of the Earth's crust is silicon. Silicon is a major component of many minerals, especially silicates, which are the most abundant type of minerals in the Earth's crust. It often forms tetrahedral structures with oxygen, creating a wide variety of minerals that contribute significantly to the composition of the Earth's crust.

Answer 6

Oxygen, constituting approximately 26% of the Earth's crust by mass, is a vital element in the planet's composition. This abundance is primarily attributed to the prevalence of oxygen in various minerals, such as silicates and oxides, which form the fundamental building blocks of the Earth's solid outer layer. The significance of oxygen extends beyond its role in geological formations, as it is a crucial component for life and plays a key role in various chemical and physical processes shaping the Earth's dynamic environment.
