[Part 2] Weather Hazards and Climate change ☂️🌐 Flashcards
Explain how climate change can negatively affect people, because of sea levels
Hint: rise
- climate change can make the sea warmer, causing the water to expand- which means sea levels rise.
- ; if sea levels do rise, flooding can happen which can damage people’s properties.
How can climate change can negatively affect the environment ?
Hint: glaciers
- climate change can negatively affect the environment, by to damaging ecosystems and cause rivers to dry up.
- this is because, glaciers provide water for important rivers [such as the Ganges river]
- ; glacier retreat [due to climate change] can lead to flooding in the short-term, which then causes rivers to dry up, or damage ecosystems.
Explain how climate change can negatively affect people, by drought.
Hint: yield
- climate change leads to higher temperatures and, therefore more frequent droughts.
- this can negatively affect farming. For example, yields of maize have gotten smaller recently.
- and if there are lower crop yields, food shortages (areas near the equator) increase leading to malnutrition and ultimately death.
What climate does the UK have ?
- the UK has a mild climate, that consists of: cool, wet winters + wet summers.
Fill in the gaps about the UK’s temperature:
The UK’s temperature follows a ________ pattern.
This means that the highest temp is between the months of ____ and ______. However, the lowest temp is between the months of _______ and ________.
The UK’s temp range is 13c.
The UK’s temperature follows a seasonal pattern.
This means that the highest temp is between the months of July and August. However, the lowest temp is between the months of January and February.
The UK’s temp range is 13c.
Fill in the gaps about the UK’s precipitation:
Like temperature, the UK’s precipitation follows a _______ pattern.
This means that the highest amount of precipitation is between October and _______. The UK’s lowest precipitation is between the months of April and ____.
But, it fluctuates between February and March.
Like temperature, the UK’s precipitation follows a seasonal pattern.
This means that the highest amount of precipitation is between October and January. The UK’s lowest precipitation is between the months of April and July.
But, it fluctuates between February and March.
Fill in the gaps about the UK’s sunshine hours:
Like temperature and precipitation, The UK’s sunshine hours also follow a _________ pattern.
This means that the highest amount of sunshine hours is between the months of May and ______.
But, the UK’s lowest sunshine hours are between the months of December and _______.
Like temperature and precipitation, The UK’s sunshine hours also follow a seasonal pattern.
This means that the highest amount of sunshine hours is between the months of May and August.
But, the UK’s lowest sunshine hours are between the months of December and January.
RECAP: When is the medieval warm period and the little ice age? [2]
- The medieval warm period was a period of warming, between the Year 900-1300.
- ; the little ice age, was a period of cooling that happened after the medieval warm period.
During the medieval warm period/the medieval optimum, the average temperature increased.
What are the impacts of this ?
Hint: vegetation
- a warmer average temperature, means more vegetation growth because of longer growing seasons.
- ; an average temperature increase, means there are larger crop yields
During the maunder minimum and little ice age the average temperature decreased. What are the impacts of this?
Hint: radiation
- a drop in average temperature because of low sun activity, lead to a reduced amount of radiation received by the land.
Explain two ways how there are regional differences in temperature? [2]
Hint: cooler than, coastal
1) north and west of UK are generally cooler than south and east.
2) coastal areas have less temperature variation (through the year than inland areas), because the sea warms, and it is colder than land.
Why are there regional differences in rainfall ?
Hint: means
- rainfall tends to be higher in areas of higher elevation.
- this means mountainous areas get more rainfall than lower lying areas.
Explain why there are regional differences in rainfall and temperature ?
Hint: prevailing winds
- Because the prevailing wind in the UK comes from the south-west, meaning that moist air is brought from the Atlantic [so the west of UK usually has higher rainfall than east of UK.]
Explain how continentality gives the UK a unique climate. [4]
Hint: islands, near the sea, on the continent
- because the UK’s made up of islands, it’s surrounded by the sea.
- This means that areas near the sea are warmer, than inland areas [in winter]. This is because the sea stores up heat, and warms the land.
- But areas near the sea are cooler in the summer- because the sea takes a long to heat up + therefore this cools the land down.
- Overall, this means that the UK is milder in the winter and cooler in summer, than countries on the continent.
What does the term ‘The North Atlantic drift’ mean ?
Hint: across the atlantic
- the North Atlantic drift, is an ocean current that brings warm water across Atlantic, to the west coast of UK.
