Answer:
Devonian, Silurian, Ordovician
Explanation:
The geologic age sequence of the surface bedrock from Ithaca to water town is Devonian, Silurian, Ordovician.
A bedrock is the hard, solid rock under the material surface of soil or grovel. The material that is on top of the material layer is mostly unconsolidated rock usually consisting of loose particles. Bedrocks have the capacity to expand hundreds of meters. They can even be found extended all the way to the earths crust.
Fossil fuel are cheap and easy to use, but pollute the earth so no we shouldn't use it, and we should work on greener sources of energy that can power a nation! (Still not there yet though.)
Answer:
The best answer to the question: With the discovery of magnetic reversals, there was evidence that:___, would be: the sea floor could create new continental crust.
Explanation:
The theory of sea floor spreading, which came from the studies of how continents formed, and the general mechanics of geology and geophysics, led scientists, since the 1960´s to understand how continental crust, and new land, is formed from the Earth´s lava mantle and the core. This sea floor spreading has been defined as the process during which, as mid-ocean ridges, which delimit two continental plates, move apart, weakening the crust, magna is able to pour through the ridge and form new crust. In relation with magnetic reversals, it must be said that this new crust that forms as lava pours forth will be magnetically charge at the time of its deposition on the surface, and as it cools down, it will store in it the magnetic charge to which it was exposed in the mantle before it was poured forth. As such, magnetic reversal shows that the earth has changed polarity throughout time, polar reversals, and these reversals have been proven through rock evidence that has been present in the ocean ridges, almost like records of the magnetic event.
The answers are:
a. physical geography
b. human geography
Geography is divided into two main branches, physical geography, and human geography, and after that, they branch out much more and include the other geographical disciplines in them.
Physical geography is mainly concerned with the study of the natural characteristics of the Earth, both the ones on the surface and the once close to the surface.
Human geography is mainly focused on the study of the human race, the background, perceptions, interactions, organizing, human groups, effects on and from the environment etc.
Answer: I guess the explanation is the answer
Explanation: An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction.
