  3. Mercalli Scale

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All three following instruments are useful in measuring the seismic activity under the earth's surface. A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions. Richter scale a quantitative measure of an earthquake's magnitude. The modified Mercalli intensity scale also measures the effect of an earthquake on the Earth's surface.

The Mercalli scale grades the earthquake on _____________.

  1. 10-point scale

  2. 12-point scale

  3. 15-point scale

  4. 20-point scale

B Correct answer
Explanation

The modified Mercalli intensity scale also measures the effect of an earthquake on the Earth's surface. The Mercalli scale grades the earthquake on a 12-point scale. The intensity scale helps to analyze the data by constructing isoseismal curves, which are lines that connect points of equal intensity.

  3. Both A and B

  4. Saffir-Simpson scale

C Correct answer
Explanation

  • There are a number of ways to measure the magnitude of an earthquake. The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.
  • Another way to measure the strength of an earthquake is to use the Mercalli scale. Invented by Giuseppe Mercalli in 1902, this scale uses the observations of the people who experienced the earthquake to estimate its intensity.

A Correct answer
Explanation

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Decibel is a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.

The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the size of an earthquake.

Kaleidoscope operates on the principle of multiple reflection, where two or more reflectors are placed at an angle to one another. When the eye is placed at one end of the reflectors, the original view from the aperture on the other side is multiplied into a symmetrical mosaic pattern. A two-mirror kaleidoscope yields a circular pattern isolated against a solid black background, while the three-mirror equilateral triangle type yields an infinite pattern that fills the entire visual field.

  1. Cascograph

  2. Seismograph

  3. Earth machine

  4. None of these

B Correct answer
Explanation

A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions, and explosions. Seismometers are usually combined with a timing device and a recording device to form a seismograph

Activities like walking, climbing, pulling, pushing etc need  ____________.

  1. solar energy

  2. muscular energy

  3. wind energy

  4. mechanical energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Activities like walking, climbing, pulling, pushing etc need Muscular energy.
Muscular energy is the conscious movement of energy along the lines of the body, drawing muscle to bone and connecting limbs to joints as the energy moves ever inward to the body's core.

 Sum of potential energy and kinetic energy is called ______________.

  1. mechanical energy

  2. muscular energy

  3. solar energy

  4. wind energy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sum of potential energy and kinetic energy is called Mechanical energy.
The mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
