Q5.
The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.
Q6
The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy
B. a few kilometers below Earth’s surface.
C. just below Earth’s surface.
D. on Earth’s surfac
Most metamorphic processes take place B. a few kilometers below Earth’s surface.
Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.
There are other ways that metamorphic rocks can form, Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.
Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

Most metamorphic process takes place a few kilometres below Earth’s surface. The metamorphic process occurs due to the presence of intense heat and high pressure below the surface of Earth.
Further Explanation:
The metamorphism of rocks is due to either due to the physical or chemical alteration by dense heat and high pressure exhibited by a sedimentary or igneous material into a denser form. Rocks are compacted into a smaller volume of space due to actions of tectonic plates, presence of shearing forces for a more extended period, stress and compression. All these factors play an essential role in the wrapping and deformation of rocks.
Due to this, the metamorphic rocks are denser than the original sedimentary material. So such rocks are less susceptible to breakdown due to erosion. The process of metamorphism is also influenced by chemically active fluids that are circulated around the newly forming rock and also introduce different ions results in the formation of a new and different mineral.
