Evolution by natural selection provides an explanation for the diversity and survival of living things. Elements consist of one type of atom, and compounds consist of atoms of different elements chemically combined. The electromagnetic force produces both electricity and magnetism. Earth and its climate have changed over geological time.

Life processes are performed at the cellular level. The behaviour of matter can be explained by the kinetic molecular theory and atomic theory. Energy can be transferred as both a particle and a wave. The theory of plate tectonics is the unifying theory that explains Earth’s geological processes.

Cells are derived from cells. The electron arrangement of atoms impacts their chemical nature. Electric current is the flow of electric charge. The biosphere, geosphere, hydrosphere, and atmosphere are interconnected, as matter cycles and energy flows through them.​
