Which statement forms part of cell theory? cell organelles are capable of reproducing themselves. cells differ in shape, but they have identical components. all cells begin life as prokaryotic cells. all living things are made up of cells.

idk im sorry.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
