What are the percentages of elements in the Earth's spheres?

In summary, the Earth's spheres consist of the hydrosphere, atmosphere, geosphere, and biosphere. The hydrosphere is made up of water and covers about 70% of the Earth's surface. The atmosphere, which is composed of gases, makes up about 78% nitrogen and 21% oxygen. The geosphere, or solid Earth, is made up of different layers and elements, with iron and oxygen being the most abundant. The biosphere is the part of the Earth where living organisms exist, and it makes up a very small percentage of the Earth's total mass. Overall, the Earth's spheres are a complex and interconnected system, with each element playing a crucial role in sustaining life on our planet

I am a 6th grader in Texas and I sometimes need some answers! (like everyone here, duh) Right now, I am trying to figure out the percentages of elements in all the 4 spheres because somehow, they are not on the internet! Can anyone help?

Welcome to PhysicsForums! It's good to have you here. :smile:

For schoolwork questions, please start a new thread in the Homework Help, Introductory Physics forum and describe the problem well and show your work and initial thoughts on the solution.

If this is not for schoolwork, you can start a new thread in the Classic Physics forum and mark it with a "B" prefix to indicate it is at a Basic level. Then do the same thing about describing the question well and show your initial thoughts. Enjoy PF! :smile:

BTW, when I do a Google search on your terms percentages of elements in all the 4 spheres I get lots of good hits, including some that discuss the percent of some of the elements in each sphere. Here is one example, but there are better ones on the Google hit list:
