The last one, " Scientists predict a volcano will erupt based on current volcanic activity." This one is false because they actually predict a volcanic eruption by the volcanic waves and other complicated things.
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:
Index fossil that is also known as indicator fossil is used to determine the age of the layers of the rocks. It says that the new layer of sedimentary rocks lie over the old layer.
The deeper we go, the older the rocks we will find. Index fossil of animals that lived or survived only for a short period of time are very useful. An example of index fossil can be Ammonites that were found in Mesozoic era that was about 25-35 million years ago.
Their location, or layer
The cells produce three germ layers:
endoderm- becomes the gut
mesoderm- becomes muscle, skeletal system, some organs, and connective tissure
ectoderm- becomes skin and nervous system
