Earthquakes

Question 1

What is a jault live

Answer 1

A fracture in the rock where pressure builds up if the plates stick

Question 2

What is an epicentre

Answer 2

The point on the Earth surface directly above the focus

Question 3

What is the focus

Answer 3

The point underground where plates slip

Question 4

what is a seismic wave

Answer 4

Energy waves that radiate out from the focus and cause the ground to shake

Question 5

What is the magnitude of an earthquake?

Answer 5

The amount of energy the earthquake releases alongside how bad the destruction from the earthquake was

Question 6

what does the Richter scale measure and what does it go up in?

Answer 6

The richter scale measures earthquakes and goes up in x30

Question 7

What is liquefaction?

Answer 7

when soft sediments acts like liquids after being shaken by seismic waves

Question 8

Is liquefaction a primary hazard of earthquakes

Answer 8

Yes

Question 9

are buildings collapsing a primary hazard of earthquakes?

Answer 9

Yes

Question 10

Is the ground shaking a primary hazards of an earthquake?

Answer 10

Yeah

Question 11

Is buildings collapsing because of the strain put on them as the ground shakes a primary or secondary hazard of earthquakes?

Answer 11

Primary hazard

Question 12

is the ground shaking and displacement which is caused by seismic waves are primary or secondary hazard of earthquakes

Answer 12

It is a primary hazard

Question 13

Is liquefication a primary or secondary hazard of earthquakes?

Answer 13

It is a primary hazard of

Question 14

Is landslides and avalanches a primary or secondary hazard of earthquakes

Answer 14

it is a secondary hazard

Question 15

Are quake lakes ,which are formed if landslides block river valleys and leads to flooding, a secondary or primary hazard of earthquakes

Answer 15

secondary

Question 16

Or tsunami is a primary or secondary hazard of earthquakes?

Answer 16

Secondary

Question 17

What are physical factors that affect earthquakes (list three)

Answer 17

depth of focus,Distance from epicentre, geology

Question 18

what are human factors that affect the severity of earthquakes? (Name three)

Answer 18

Time of day, population density, level of development

Question 19

how does the depth of focus affect the impact of an earthquake

Answer 19

The closer of the focus to the top the stronger the shaking as little energy is lost

Question 20

How does the distance from the epicentre affect the severity of the earthquake?

Answer 20

The further from the epicentre, the weaker the shaking as energy is lost

Question 21

How does geology affect the severity of an earthquake?

Answer 21

soft rocks and sediments are easily shaken more severely causing a great impact

Question 22

How does time of day affect the severity of an earthquake

Answer 22

when in the night, most people are asleep and therefore it is easier to escape an earthquake

Question 23

how does the level of development affect the severity of an earthquake

Answer 23

The more developed countries deal with earthquakes better as they have more advanced technology and building strategies

Question 24

How does the population density affect the severity of an earthquake?

Answer 24

The more densely populated an area, the more Potential of the negative impacts
