So I will match them but by words so if necessary you will have to do the number letter pairing.. kool:
protons plus neutron = atomic mass
proton number = atomic number
detects radiation = Geiger Counter
fixed shape = solid
neutral charge = neutron
positive charge = proton
occupies the whole container = gas
measures the intensity of radiation = photographic film
smallest particle to retain characteristics = atom
negative charge = electron
Hope this helps and doesn't leave you with too much work
Answer:
These vents contribute dissolved minerals to the oceans, which is one reason the oceans are salty. Rivers and surface runoff are not the only source of dissolved salts. Hydrothermal vents are recently-discovered features on the crest of oceanic ridges that contribute dissolved minerals to the oceans.
