Answer:

d) All of the above

Explanation:

  • Three main types of magma are Basaltic magma, Rhyolitic magma and Andesitic magma.
  • Basically Andesitic magma is formed through the wet partial melting of the mantle under the ocean which has contact with water. .It is generated in the wedge of the mantle rock below the crust and above the subducted plate itself. Andesitic and rhyolitic magmas are generated at convergent plate boundaries where the oceanic lithosphere is subducted .
  • Comparatively high silica content ( 55 - 65 weight %) and lower temperature result in high viscosity and low gas content of Andesitic magma.

Answer:

The universe is comprised of more than 75% of materials that are not visible and are often considered to be the dark matter. These are the baryonic matter that is formed due to the accumulation of protons, neutrons as well as electrons. They can be baryonic or non-baryonic type of matter. These dark matters are the substance that interconnects mostly by gravity along with some visible matter such as the stars and planets. These matters do not reflect light and they attract other matters, forming the major mass of the entire universe.

vlabodo [156]

Answer:

B

Explanation:

Oceanic crust is the Earth's lithosphere's outermost layer located under the oceans and formed on the oceanic ridges at spreading centers that occur at divergent plate boundaries (ridge axis).

It is covered by a thin blanket of sediment that thickens away from the ridge axis.

Oceanic crust is different from the continental crust in numerous ways. For instance; It is younger, thinner, and denser than continental crust. Furthermore, It also has a different chemical composition.
