Option 4 : Geothermal energy

The correct answer is Geothermal energy.

  • "Geo" = Earth, "Thermal" = Heat.
  • Geothermal energy is the heat energy obtained from within the Earth. Therefore not derived from Sun's energy.
  • Geothermal Energy:
    • ​The heat that comes from the earth's subsurface is known as geothermal energy.
    • It can be present in the minerals and fluids underneath the earth's surface, as well as in the hot molten rock known as magma.
    • Mile-deep wells are drilled into underground lakes to access steam and hot water, which can then be used to power turbines attached to electricity generators.
    • Dry steam, flash, and binary geothermal power plants are the three types of geothermal power plants.

In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The questions below is followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
