Answer:
sedimentary (ex: limestone), metamorphic (ex: marble), igneous (ex: granite)
Explanation:
sedimentary, metamorphic, and igneous are the 3 types of rocks formed by the rock cycle. didnt know if you only needed that or examples of each kind so I gave both. also not important but a fun fact igneous means made by fire, metamorphic (think of a butterfly, they go through metamorphosis) this means they change, and sedimentary (rocks pressed together to form a new one often found after events such as erosion, etc). hope this helps :)
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).
