did that help?
Explanation:
The scientist that studies earthquakes is a ➡️"seismologist"⬅️
For future reference break down the word, get the root. if you don't know what the root-word means look it up in the dictionary, it should help :)
Good luck on your assignment and enjoy your day!

Answer:
C. The greater an element's density, the smaller the amount of it found in the crust
Explanation:
The layering of the Earth happened because of the different densities of the elements from which it was made. The denser elements started to sink deeper, the elements with medium density occupied the central part, and the elements with the smallest density remained at the surface. This resulted in the formation of the three basic layers of the Earth, core, mantle and crust. The core is composed of the densest elements, the mantle of the ones with medium density, and the crust from the ones with smallest density.
Usually to begin they use the process of relative dating,
then chemical dating. Then look at where the environment that we found the
fossil to determine if it has always been that environment. When fossil is found in marine life in a
country town suggesting that the environment was previously a marine
environment. Study the rocks that they
found the fossils to help determine a relative age. This came before that, but
after them to give us an approximate age. Then study the fossil itself to
classify it into groups to determine which branch of evolution it has come
from. Fossils can be found in rocks, bedding planes, (rock layers), trees (tree
ring dating). Mostly there are found in rocks or weathered rocks (sands, mud).
