Weather and Climate
Cards in this deck (19)
- 1What is the differerence between weather and climate?Weather is the day-to-day variation of features such as rainfall, temperature,
wind, whilst climate represents the average weather conditions – over a period of time, average of at least 30 years. - 2What are the five main reasons why the climate varies in the UK?Latitude - (how far north or south of the equator), Distance from the sea, Winds, Pressure and Altitude.
- 3What is a depression and how does it form?Is a low pressure system, is formed over the atlantic ocean then moves east across the uk.Forms by warm moist air -- tropics meets cold dry air --poles. The warmless dense air rises above the cold. Condensation happens and causes rain clouds.air rising causes low presure on earth.there is a warm front, occluded front and cold front
- 4What is the sequence of weather caused by a depression?
- 5What is an Anticyclone? ,and what do they cause?Cause clear skies and dry weather, where air is falling causing high pressure and light wind. The air gets warmer no clouds are formed so no rain for days. In summer long periods of dry, hot, and clear weather. In winter long periods of cold foggy weather.
- 6Name 3 things that show that weather in the UK is becoming more extreme?Its raining more, the rainfall is more intense and temperature is increasing. Many new records are being recorded.
- 7What was extreme weathe in the UK led too?Major flooding caused by storms and high rainfall examples of theses are Cumbria (2004), Midlands (2007), Devon (2008).
Strong winds and high tides caused major flooding in norfolk (2006). High temperature have led to drought in 2003 and major heatwaves. - 8What are the impacts of extreme weather?Peoples homes and livelihood damaged by flooding. Agriculture can be affected by heat and water. Health as peoples lives may be at risk. Transport can be affected by flooding and heat.
- 9How can negative impacts of extreme weather be reduced?Preparing, Planning and Warning
- 10What is Climate change and What is Global Warming?Climate change is any change of weather of an area overa long period of time.
Global warming is a type of climate change and it causes other types of climate change like increase in rainfall. - 11What is the Evidence for and against Global warming?For: Rising temperature in the last 150 years, ice sheets are melting and sea levels are rising. Against: people argue global warming evidence is dodgy, they say that because human settlements have got closer to where the measurements are taken they may be inaccurate as man made surfaces like concrete absorb and radiate more heat.
- 12What causes global warming?Increase in human activities eg burning fossil fuels, farming and deforestation.
- 13Impacts due to global climate change?Economic, there will be more money will be spent on predicting weather, some farms will make/lose money.Social, more deaths, uninhabitable countries and less places to grow food. Environmental impacts, many plant and animal species will die. Political are water will be more scarce, increase in population in certain countries.
- 14What are the global responses to climate change?Kyoto protocol, this was where countries agreed to monitor and cut greenhouse gas emissions from (1997-2012). Carbon credits which are where every country are given a certain amount of carbon credits if they use they all they can buy of other countries that have not used all there're earn them by helping poorer countries.
- 15What are the National and local responses to climate change?National - Transport strategies and taxation to people who have high emission cars.
Local - Recycling, Congestion charge and Conserving enegy. - 16What are Tropical storms?Intense low pressure weather systems, they are called different names such as hurricanes, typhoons and tropical cyclones.
- 17How do tropical storms form?They form over sea water that's higher than 27 degrees, Warm moist air condenses and rises. this releases huge amounts of energy which makes storms powerful. They move because of easterly winds near equator. they lose strength over land because the energy supply from water i cut off. They occur between 5 and 30 degrees .
- 18What are the Characteristics of a tropical storm?They spin anticlockwise and last between 7 and 14 days
- 19What are the 3 types of rainfall?Relief- warm moist air, rises over mountains, descends and warms rain stops and falls.
Conventional- Ground warmed by sun, warm air rises, air cools and forms clouds then rains.
Frontal- warm air rises over heavier cooler air, rising air cools, clouds and rain.
