  1. Non-mechanical waves

  2. Elastic waves

  3. Mechanical waves

  4. Electromagnetic waves

Show answer
Correct Option: C

The movement of Earth's plates causes

  1. Lightening

  2. Cyclons

  3. Earthquake

  4. Thunderstorms

Show answer
Correct Option: C
Explanation:

The movement of Earth's plates causes Earthquake. Earth's crust is broken up into large pieces called tectonic plates. Tectonic plates are giant pieces of the Earth's crust that fit together and move around on the Earth's surface. Tectonic plates are constantly moving slowly, but sometimes friction between them causes them to lock together and become unable to move. The rest of the plates carry on moving, which leads to increased pressure on the locked section. Eventually, the locked section succumbs to the pressure, and the plates move past each other rapidly. This movement causes a tectonic earthquake. The waves of released energy move through the Earth's crust and cause the shaking we feel at an earthquake site. 

Which of the following is not a after-effect of earthquake?

  1. Destruction of livelihood

  2. Death and injuries

  3. Water waves and tsunamis

  4. Rainfall

Show answer
Correct Option: D
Explanation:

An earthquake is a sudden shaking movement of the surface of the earth. The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, liquefaction, destruction of livelihood. death and injuries. Rainfall is not an after-effect of earthquake.

Earthquake can cause

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

  1. Tsunami

  2. Floods

  3. Landslide

  4. All of the above

Show answer
Correct Option: D
Explanation:

The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, flood and liquefaction. Fires are probably the single most important secondary effect of earthquakes.

State whether the given statement is True or False :

Tremors on the Earth can also be caused by the eruption of a volcano. 

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:
Tremors on the Earth can be caused when a volcano erupts, or a meteor hits the Earth, or an underground nuclear explosion is carried out. However, most earthquakes are caused by the movement of Earth’s plates.

State whether the given statement is True or False :

Earthquakes occur all the time all over the world. 

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:
The statement is true. Earthquake in less magnitude are not even noticed. 

Seismic waves that vibrate perpendicular to the direction of their path.

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

  1. Spread on the surface of the earth

  2. Travel through the solid as well as other parts of the earth

  3. Travel through the solid parts of the earth only

  4. None of the above

Show answer
Correct Option: C
Explanation:

Seismic waves that vibrate perpendicular to the direction of motion travel through the solid parts of earth only.

Earthquake 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. nektons

  2. blusters

  3. temblors

  4. flickers

Show answer
Correct Option: C
Explanation:

An earthquake also known as a temblor, quake, tremor is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Which of the following is/are true regarding Earthquake ?

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

  1. It refers to shaking of the Earth.

  2. It occurs due to release of energy.

  3. It generates waves that travel in all direction.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

Earth's crust is broken up into large pieces called tectonic plates. Tectonic plates are giant pieces of the Earth's crust that fit together and move around on the Earth's surface. Tectonic plates are constantly moving slowly, but sometimes friction between them causes them lock together and become unable to move. The rest of the plates carry on moving, which leads to increased pressure on the locked section. Eventually, the locked section succumbs to the pressure, and the plates move past each other rapidly. This movement causes a tectonic earthquake. The waves of released energy move through the Earth's crust in all direction and cause the shaking we feel at an earthquake site.
