Melting above the subducted slab produces mafic magma, as described above, yet intermediate rocks (andesite, diorite) between oc

eanic and continental lithosphere, explain how this intermediate magma forms.
(a) A relatively small amount of intermediate magma occurs in volcanic island arcs. Remembering that melting above the subducting slab produces mafic magma, explain the origin of the intermediate magma.
(b) Much more intermediate magma erupts in continental arcs. Why?

Answer and Explanation:

A. Intermediate magma occurs with the partial melting of the overlying ultramafic oceanic crust. This melting is caused by the fluids released by the subducted slab. As a result of this parvial melt there is a magmatic differentiation where the formed magma leaves a material residue, called intermediate residue, which is assimilated by the basaltic magma, thus forming the intermediate magma.

B. This is because as the intermediate magma is produced, the continental crust is either assimilated by it, or melted and assimilated by the magma.

Felicity is taking a test. She has to write about the importance of biomass. Which point should she include in her answer?
maxonik [38]

Answer:

Explanation:

Biomass refers to the organic matter from plants and animals.

It is also a source of renewable energy which can be used to produce electricity.

Energy from biomass orginates from the process of photosynthesis where green plants manufacture food for the ecosystem using carbon dioxide and sunlight.

Biomass has the following use:

It is widely available: Biomass can easily be sourced for. It is widely abundant in the environment.

It is inexpensive: Due to its wide availability, its source materials are very cheap and lies readily in the environment when we compare this to exploration for fossil fuels and mining for uranium.

It is carbon neutral: Since biomass constitutes a part of the carbon cycle, energy from biomass does not lead to climate change. Green plants use carbondioxide to manufacture their food and it is released back to the atmosphere when biomass is tapped.

It is environmentally friendly: The use of biomass as a source of energy does not affect the environment negatively. It is a clean source of energy.

It helps to reduce amount of waste: biomass energy helps us put wastes into a very good use.
