Fill in the blank:

The uppermost layer of the Earth is called _______.

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

  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.

Tremors on the earth can also be caused when?

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

  1. Valcano erupts

  2. Metero hits the earth

  3. Underground nuclear explosion

  4. All of the above

Show answer
Correct Option: D
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.

The intensity of an earthquake is measure on the ______?

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

  1. Righter scale

  2. Richter scale

  3. Seismic scale

  4. None of the above

Show answer
Correct Option: B
Explanation:

Magnitude of earthquake is measure on Richter scale really distructive earthquake have magnitude higher than $7$ on the Richter scale.

The Earth's crust plates moves brushing past each other or collide. It causes:

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

  1. landslides

  2. volcanic eruption

  3. earthquake

  4. none of the above

Show answer
Correct Option: C
Explanation:

Any disturbance deep inside the Earth's crust leads to earthquake.

The uppermost layer of the Earth is:

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

  1. a huge single piece

  2. fragmented

  3. in two large pieces

  4. none of the above

Show answer
Correct Option: B
Explanation:

The Earth's crust is not a huge single piece. It is fragmented into pieces.

The plates or the fragments of the Earth's crust is 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. crust plates

  2. surface plates

  3. tectonic plates

  4. none of the above

Show answer
Correct Option: C
Explanation:

Earth's crust is fragmented into pieces which are called plates. These plates are also known as tectonic plates.

Fill in the blank:

Most destructive earthquakes have magnitudes _______ on the Richter scale.

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

  1. $4$

  2. $7$

  3. less than $7$

  4. higher than $7$

Show answer
Correct Option: D
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.
