Solution :
The type of melting that is responsible for the mafic magmas for the following plate tectonic settings :
a). Mid - ocean ridges
At the mid oceanic ridges, the two plates diverges away and the new oceanic crust is formed by the effusion of the magma. The earth's interior is exposed as the two plates are moved away.
b). Continental rift :
A new oceanic crust is formed by the effusion of the magma and the two plates diverges away. Thus it causes the formation of the melt in the continental drift. As a result, the crustal thickness decreases.
c). Oceanic and continental volcanic arc :
The oceanic arc and the volcanic arc are the locations of the convergence. The denser plate of the arcs subducts under the less denser plates or the lighter plates and it moves downwards into the mantle, which causes the increase in temperature of the surroundings.
No. The earth is not flat.
Answer:
B. when they impact Earth.
Explanation:
- Asteroids are minor planet type rocky masses that are broken off and found in the inner solar system and also been called the inner planetoids as they are orbiting around the sun. They are similar to comets based on surface features.
- Computerized methods are used to find out the presence of asteroids in the shy. The asteroid belt has tended to evolve in the nebula formation of the sun with the presence of heavy metals sinking in the ice cores leaving the rocky mineral in the crust. They are almost 1000 km to 1 meter wide and can be large as miniature planets
- However waste the majority of them are irregular in the shade the three largest asteroids are Ceres, Vesta, and Pallas that form a type of the dwarf planet.
A meander is best described as a bend or curve in a stream channel.
