<u>Answer:</u>
Granitic rock in the ocean floor was not included in the support for Harry Hess's hypothesis of sea-floor spreading.
<u>Explanation:</u>
- Separation of the ocean floor which leads to the expansion of the ocean is called as sea-floor spreading.
- By this process there is formation of oceanic crust that are formed by volcanic activity along with the mid-oceanic ridge.
- Rock are basaltic and dense in nature. By this theory, it is suggested that the rock which are present near the mid-oceanic ridge are younger and the rock which are far from them are older than them.
- Plate tectonic movement is the cause for the sea-floor spreading.
Explanation:
The law of conservation in generation of electricity from fossil fuels;
Fossil fuels are derived from the remains of plants and animals.
These fuels stores and preserves chemical energy which have produced through their activities which originates from the sun as form of solar energy.
The chemical energy is obtained for used as fossil fuels.
As fuels, they combine with oxygen in power generating plant to produce heat energy. The combustion process transforms chemical energy to heat energy.
The heat energy is used to heat boilers of water to produce steam. Heat energy is expressed as thermal kinetic energy which are converted to mechanical energy to drive turbines. The turbine is connected to a generator where electricity is produced.
This totally agrees with the law of conservation of energy.
The law states that "energy is neither created nor destroyed but transformed from one form to another"
Chemical energy - heat energy - mechanical energy - electrical energy

The electromagnetic radiation with wavelengths between 380 nm and 700 nm is visible light (option D).
<h3>What is electromagnetic spectrum?</h3>
Electromagnetic spectrum is the entire range of wavelengths of all known electromagnetic radiations extending from gamma rays through visible light, infrared, and radio waves, to X-rays.
The electromagnetic spectrum is made up of the following radiations separated by differing ranges of wavelengths;
- ultraviolet (400 nm - 1 nm)
- visible: (750 nm - 400 nm)
- near-infrared: (2.5 μm - 750 nm)
- infrared: (25 μm - 2.5 μm)
- microwaves : (1 mm - 25 μm)
- radio waves : > 1 mm
Therefore, the electromagnetic radiation with wavelengths between 380 nm and 700 nm is visible light (option D).
