Waves produced due to earthquakes are known as :

  1. seismic waves

  2. shock waves

  3. infrasonic waves

  4. destructive waves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion, which travel through the earth's layers.

Multiple choice physics structure of earth seismic waves and tsunami causes of earthquakes origin of earth and its internal energy transfer of charge lightning safety

Waves produced due to the earthquake are known as

  1. seismic waves

  2. shock waves

  3. infrasonic waves

  4. Tectonic waves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seismic waves are the scientific term for waves produced by earthquakes. While shock waves describes their nature and many are infrasonic, seismic waves is the correct terminology used in seismology to describe waves that travel through Earth's layers.

The inner most part or the centre of the Earth is known as ________.

  1. outer core

  2. inner core

  3. mantle

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

Earth consist of core, mantle and crust. Core is the centre of the Earth. Core, again, consists of inner core and outer core. Inner core is inner most part, or, the centre of the Earth.

Fill in the blank:

Most destructive earthquakes have magnitudes _______ on the Richter scale.

  1. $4$
  2. $7$
  3. less than $7$
  4. higher than $7$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An earthquake of magnitude 7 is found to be destructive. And, obviously, most destructive earthquakes are of magnitude higher than 7 on the Richter scale.
