weather hazards and climate change

Question 1

Define hazard risk

Answer 1

The degree of likelihood that harm will be caused by a natural hazard

Question 2

Define natural hazard

Answer 2

A natural event that has the potential to cause harm to human life or property

Question 3

Define economic impact

Answer 3

An impact which affects the wealth of a place or someone’s income

Question 4

Define immediate responses

Answer 4

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

Question 5

Define long-term response

Answer 5

A response in the months and years after a disaster has happened

Question 6

Define monitoring

Answer 6

Recording physical changes, such as as earthquake tremors around a volcano to help predict when/where a natural hazard might strike

Question 7

Define prediction

Answer 7

Attempts to forecast when and where a natural hazard will strike, based on current knowledge

Question 8

Define primary effects

Answer 8

The initial (first) impact of a natural event on people and property

Question 9

Define protection

Answer 9

Actions taken before a hazard strikes to reduce its impact, such as educating people

Question 10

Define secondary effects

Answer 10

The subsequent impacts of the primary effects which happen later

Question 11

Define social impact

Answer 11

An impact which affects human well-being

Question 12

What are the three different ways of saying tropical storm

Answer 12

cyclone, hurricane, typhoon

Question 13

What is a tropical storm that has had a significant effect on people and the environment

Answer 13

Typhoon Haiyan - Philippines (2013)

Question 14

What is an example of an extreme weather event in the UK that has had impacts on human activity

Answer 14

The ‘Beast from the East’ - UK (2018)

Question 15

What are 3 types of natural hazards

Answer 15

tectonic
atmospheric - (hazards and climate change (larger))
geomorpholgical

Question 16

Name factor affecting hazard risks

Answer 16

Magnitude
Population density
Time of day

Question 17

What are the layers of the earth

Answer 17

Crust
Mantle
Outer core
Inner core

Question 18

How do ice cores contain evidence of climate change

Answer 18

They contain CO2 trapped in the ice - so by analysing these layers we can discover the concentration of CO2 during the years - a black line / ash layer in the ice core usually suggests a volcanic eruption has occurred

Question 19

How do temperature records contain evidence of climate change

Answer 19

Through comparing data from the present day since about 1850.

Question 20

How does pollen analysis contain evidence of climate change

Answer 20

Pollen is found in peat bogs. It tells us which plants were growing at the time, which tells us whether the climate was warm or cold.

Question 21

How do tree rings contain evidence of climate change

Answer 21

The rings are thicker when the climate is warmer and wetter (thinner in cold and dry climates) - dendrochronology - shows climate proportions

Question 22

How does the size of the stomata contain evidence of climate change

Answer 22

Smaller stomata - large CO2 concentration
Larger stomata - less CO2 concentration
