Answer:
B. Pacific Ocean
Explanation:
According to the map description, the ocean identified with the number 1 is the Pacific Ocean. We can see this, because according to the description, this ocean is on the left side of the American continent, covering the entire territory that includes North America to South America. The ocean that is located in this region is the Pacific Ocean.
Answer: 15 million square km.
Explanation:
The rainforests cover about 2 percent of the total area of the Earth surface but the 50 percent of the animals and plants of the earth live in the rainforest. The rainforests can be found in different countries of the world. These can be found in Alaska, Canada, Asia, America and Africa. The rainforest cannot be found in Alaska because the temperature in Alaska is too cold.
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.
Answer:
Hilly flanks theory
Explanation:
HILLY FLANKS THEORY is the theory proposed by Robert Braidwood, arguing that agriculture arose in areas where the wild ancestors of domesticated wheat and barley grew, and resulted from human efforts to increase the productivity and stability of their food base.
He proposed and suggest in 1948, that agriculture began in the hilly flanks of the Taurus and Zagros mountains, where the climate was not drier, as Childe had believed, and that fertile land supported a variety of plants and animals amenable to domestication.
