1.4 Impact and Response

Question 1

3 variablees that may effect the severity of an earthquake

Answer 1

time of day
size of earthquake
population density

Question 2

what are Short-term responses

Answer 2

a response in the days and weeks immediately after a disaster has happened.

Question 3

what are Long-term responses

Answer 3

responses that go on for months and years after a disaster.

Question 4

Explain one way short-term relief helps to reduce earthquake impact in a developing country (2 marks)

Answer 4

Short-term relief efforts such as emergency shelter, food and water distribution can help reduce the immediate impact of earthquakes in developing countries. These efforts provide basic necessities to those affected, preventing further harm and loss of life.

Question 5

how does soil liquefaction occur?

Answer 5

Soil liquefaction occurs when a saturated or partially saturated soil loses strength when shaking happens during an earthquake. The material that is ordinarily a solid behaves like a liquid.

Question 6

what is soil liquefaction?

Answer 6

Soil liquefaction is when water-saturated soil becomes liquid-like during seismic activity like an earthquake. It loses strength and stiffness due to increased pore water pressure, reducing its ability to support structures. This can lead to structural damage, sinking, tilting, or collapsing of buildings, and ground deformations.
