Question

Arrange the events to describe how one earthquake happens.

1)The plates create great stresses in rocks near the edges of the plate

2)The intensity of the earthquake reduces with the distance from the epicenter

3)Large chunks of Earth called tectonic plates collide with each other

4)The seismic waves created at the hypocenter spread out radially and cause shaking wherever they travel.

5)The energy released causes shaking of Earth in that position.

6)The edges of the plates slide past each other in close contact.

7)The separation of the plates release a great amount of energy.

Answer 1

Answer: Event 3, Event 1, Event 4 and Event 2 (From first to last)

Explanation: Earthquake occurs due to the sudden release of energy in the interior of the earth. The steps that follows an earthquake are given below-

• Initially, the lithospheric plates moving over the earth's upper mantle collides with one another. This could be due to the convergent, divergent or transform plate movement.
• Due to this collision, the denser plates gets subducted beneath the lighter one, as a result of which stress generates at the edge of those plates.
• Because of this stress, seismic waves generates from the hypocenter, that radiates in all direction, causing vibration or shaking of the earth.
• Due to this shaking, earthquake occurs and the intensity is very high at the epicenter but as we move away from the epicenter, the intensity decreases.
