Answer:

Option (1)

Explanation:

The lithospheric plates are commonly known as either oceanic or continental plates. These plates covers the entire crust portion of the earth. These plates move over the layer of less dense asthenosphere due to the generation of convection current in the mantle. This occurs due to the heat provided from the core of the earth.

In a convergent plate boundary that is shared by the two oceanic plates, the two plates are of high densities and the denser one sinks beneath the less denser one. Due to this, a subduction zone is formed that is marked by a deep sea trench above it. The downgoing, subducting plate undergoes partal melting at great depth and the magma is uplifted towards the surface in the over-riding plate forming large volcanic islands. Generally the deep focus earthquakes are generated due to this type of collision.

Thus, the correct answer is option (1).

Answer:

The answer would be "convergent ocean-ocean boundary". Two plates come together and collide, the impact of the collision causes the plates to come out as mountain ranges or in this case a string of small volcanic islands. Hope that helps! :)

It oxidies iron and inorganic sulfur compounds. The oxidation process can be harmful, as it produces sulfuric acid, which is a major pollutant. It has been suggested that T. ferrooxidans forms a symbiotic relationship with members of the genus Acidiphilium, a bacterial capable of iron reduction. Other species of Thiobacillus grow in water and sediment; there are both freshwater and marine strains.

The bacteria are usually found in rivers, canals, mine drainage effluents and mining areas. So there may be some source of these bacilli near their house.They require inorganic sources to grow and contain an enzyme called ferrous oxidase that allows them to metabolize iron.
