C Correct answer
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

D Correct answer
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.

D Correct answer
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. 

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Earthquake is also known as :

  1. nektons

  2. blusters

  3. temblors

  4. flickers
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
