Human activity impacts the carbon cycle by introducing more carbon dioxide into the atmosphere: carbon dioxide accumulates in the atmosphere, changes temperatures and alters the salinity levels of oceans, disturbing the salt and water balance equilibrium that supports proper growth of marine plants and animals.
Answer: Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule.
Explanation: Atoms form covalent bonds as a result of the Octet Rule. The Octet Rule states that all atoms in a molecule need to have eight electrons in their valence shell. This rule can be satisfied by sharing, losing or gaining electrons. A covalent bond allows atoms to satisfy the Octet Rule via sharing.
