B
lithosphere, elmentsphere, and the universe.
C

D
periodic table of elements.
Explanation: 

Detailed explanation-1: -Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).

Detailed explanation-2: -Oxygen, aluminum, calcium, iron, and silicon are the most abundant elements in Earth’s lithosphere.

Detailed explanation-3: -Biosphere: The biosphere contains Earth’s living matter. All plants and animals are part of this sphere. Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus are the most abundant elements in living things. Hydrosphere: All of the water on Earth is part of the hydrosphere.

Detailed explanation-4: -The hydrosphere contains water. Water is made of oxygen and hydrogen. One molecule of water is made of 2 hydrogen atoms and 1 oxygen atom For this reason, the hydrosphere is made of hydrogen and oxygen in a 2:1 ratio of 66% to 33%.

Detailed explanation-5: -Biosphere-The sum of all living matter, made of a limited number of elements including oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
