I would say that Mercury show the most signs of volcanic activity.<span />
Answer:
The correct answer is D. The deepest parts of the oceans, located near the continents, are the oceanic trenches.
Explanation:
The ocean trenches are large depressions at the base of the seabed, which constitute the deepest parts of the Earth. Of these, the Mariana Trench, located in the Pacific Ocean to the east of China, is the deepest, being approximately 11,000 meters deep.
These trenches are formed by the activity of tectonic plates, specifically when one plate moves below the other and by the force exerted a depression is generated in the seabed, followed by a chain of volcanic islands at a close distance.
Answer:
b) Magma B
Explanation:
The magma that forms a basalt plateau or a shield volcano is a mafic (basaltic) magma. This magma is low in viscosity, making it very liquid, so when there's an eruption there's lava flows coming down the slopes like rivers, moving relatively fast. This type of magma has low content of silica, which is the reason why it is low in viscosity. The low viscosity also contributes to very small amount of gases in the magma, as the gases can escape from it very easily so they do not come in a situation to be trapped. The low amount of gases means that the volcanoes with this type of magma have calm eruptions, and explosive eruptions are either nonexistent, or extremely rare.
