It's because of Plate tectonics.
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.
4.) Movement along these plates can cause powerful earthquakes
They mostly had resources , and locations in common.
Answer:
There are mainly 4 types of volcanoes.
Explanation:
1. Cinder cones: They are a bowl-shaped crater, build from particle or blobs of congealed lava that is ejected from a single gas vent, as the air is broken into small fragments that are solidified and falls as cinders.
2. Composite volcanoes: stratovolcano or composite cone are those that form a steep-sided, symmetrical cone of large dimensions built around by lavas. Some examples are Mount Shasta in California, Mount Hood in Oregon.
3. Lava domes: There internal structure is defined by bulbous masses of lava, that are too vicious.
4. Shield volcanoes: These are built entirely by fluid lava, and flow p[ours in all directions.
A volcano can change its surrounding weather patterns but not the climate of a place as a climatic zone is composed of stable and static atmosphere like that of poles, tropics, and temperate lands, etc.
Not all volcanic eruptions can be predicted successfully as they are also triggered by an earthquake and the active or dominant type of volcano can be identified based on its previous eruption patterns.
