Answer:
B. Geothermal refers to heat sources on the Earth’s crust
Explanation:
- The geothermal energy is the heat that is derived from the storing of energy that creates by the earth's temperature and the earth's crust is origin for this type of energy along with the radioactive decay of the elements of the crust.
- <u>Thus said to be earth's internal heat and needs to be trapped as it can get lost during the formation stages. </u>
- The temperature that occurs at the earth's core and the metal zone reaches up to 4000°C and thus the high temperature causes the rocks to melt and give rise to the temperature in the plastic mantle to get activated by the convection currents that reach the surface.
- Some examples of this geothermal energy are those of the hot spring and the rising lava or the magmas.
Answer:
luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.
Explanation:
Answer:
Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.
Explanation:
"The result is a topographic depression where the oceanic plate comes in contact with the overriding plate, which may be either oceanic or continental. If the overriding plate is oceanic, an island arc develops. The trench forms an arc in plan view, and islands with explosive volcanoes develop on the overriding plate. If the overriding plate is continental, a marginal trench forms where the topographic depression appears to follow the outline of the continental margin. Explosive volcanoes are found there too"
A supplementary angle of θ° is 180° - θ°.
Supplementary angle = 180° - 74°
Answer :
106°
