I’m sorry i thought this was géographie
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).
NUMBER ONE "Natural phenomena such as earthquakes, mountain formation, and volcanoes occur at plate boundaries. Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. This type of boundary eventually results in a collision." NUMBER TWO At what type of boundaries do oceans occur? List a location where an ocean is getting wider today. . "The theory of plate tectonics is nowadays more or less universally accepted by geologists, and I have mentioned the basic idea briefly at the beginning of this class. The basic thought is, that instead of being permanent fixtures of the earth's surface, the continents and ocean basins undergo continuous change. Both are parts of lithosphere plates that move against each other, and in the process new crust is created at midoceanic ridges (spreading centers), and old crust is consumed at convergent plate boundaries (subduction zones)." NUMBER THREE "The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate."
