27. Classified as warm - water or cold - water currents






28. The science of the atmosphere and weather






29. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.
