Questions Related to structure of earth

Fill in the blank:

Seismometers can record motions in ________ directions.

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

  1. one

  2. all

  3. opposite

  4. same

Show answer
Correct Option: B
Explanation:

Seismometer devices are located in $3$ directions and work on principle of inertia to catch the motions in all directions.

  1. mantle

  2. outer core

  3. crust

  4. none of the above

Show answer
Correct Option: C
Explanation:

Earth consist of three parts core, mantle, crust. The uppermost layer is called crust.

Weak zones of plates are also known as:

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

  1. seismic zones

  2. fault zones

  3. danger zones

  4. both A and B

Show answer
Correct Option: D
Explanation:

The boundaries of the plates are the weak zones where earthquakes are more likely to occur. These are also known as seismic zones and fault zones.

The inner most part or the centre of the Earth is known as ________.
physics structure of earth seismic waves and tsunami causes of earthquakes origin of earth and its internal energy transfer of charge lightning safety

  1. outer core

  2. inner core

  3. mantle

  4. crust

Show answer
Correct Option: B
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.
