Diamond has a macromolecular structure and iodine is a simple covalent molecule. Use your knowledge of structure and bonding to explain why diamond has a higher melting point than iodine. The photo attached are key words and helpful tips that I’m meant to use and that should help (apparently)

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
