Which of the following constitutes indirect sources of information about the interior of the Earth? 1. Volcanic eruption 2. Meteors 3. Seismic Waves Correct Answer 2 and 3 only

The correct answer is option 2, i.e 2 and 3 only.

  • There are two ways to find out the information about the interior of the Earth – direct sources and indirect sources.
  • Indirect sources of information about the earth’s interior are as follows:
    • Seismic waves
    • Meteorites
    • Gravitation
    • Magnetic field
  • Direct sources of information about the earth’s interior are as follows:
    • Deep earth mining and drilling reveal the nature of rocks deep down the surface.
    • Volcanic eruption forms another source of obtaining direct information.

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. Earthquakes are the shaking and moving of the ground when energy is released in waves.   P. These waves are similar to ocean waves, which move through water. Q. These waves are called seismic waves.  R. Seismic waves, however, move through the ground. S. Earthquakes can also be caused by other natural events, such as landslides and volcanoes.  6. Manmade earthquakes happen because of nuclear testing and mining explosions.
With reference to the interior of the earth consider the following statements. 1] All natural earthquakes take place in the lithosphere. 2] The lithosphere refers to the portion of depth up to 200 km from the surface of the earth. 3] Earthquake waves are basically of four types — body waves, surface waves, rolling waves and shock waves. Which of the statements given above is / are correct?
Which of the following statements is correct regarding secondary seismic waves (S waves)? I. They are also called longitudinal waves. II. These waves cannot pass through liquid materials. III. Their speed is lower than surface waves.
With reference to secondary seismic waves (S waves) which of the following statements are correct? I. These are also called longitudinal waves. II. These waves cannot pass through liquids. III. Their speed is less than surface waves.
In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: Historically, volcanic eruptions have caused catastrophic famines. B: Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere (or troposphere); however, they also absorb heat radiated from the Earth, thereby warming the upper atmosphere (or stratosphere). C: One such hazard is that volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature; the melted particles then adhere to the turbine blades and alter their shape, disrupting the operation of the turbine. D: Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption.
Which of the following is/are matched correctly?
1. Earthquake's origin - seismic focus
2. Epicentre - point on earth's surface directly above seismic focus
3. S waves - similar to sound waves
4. Richter scale - severity of earthquake
With reference to the interior of the earth consider the following statements. 1] Body waves are generated due to the release of energy at the focus. 2] Denser the material, the lower is the velocity of the Earthquake waves. 3] There are two types of body waves. They are called P and S-waves. Which of the statements given above is / are correct?
Which of the statements given above are correct?
1. P - waves are the first seismic waves to reach a place
2. S - waves travel only through liquids
3. Arrival time of P and S - waves is used to locate the epicentre
