Geography
Unit 5 - Weather climate and ecosystems
| Question | Answer |
|---|---|
| What is the greenhouse effect? | When solar rays from the sun bounce onto the earth and then get absorbed by the greenhouse gases in the atmosphere, making our earth warmer by not letting the heat leave. |
| What human actions release CO2 into the atmosphere? | Burning fossil fuels, destroying natural carbon sinks in de-forestation and landfill sites |
| Why are rainforests and forests natural carbon sinks? | The leaves on the trees soak up carbon dioxide in photosynthesis, they then fall of and are absorbed into the soil or are washed away by rainwater. |
| What is the difference between the natural carbon cycle and the human one? | The natural carbon cycle takes roughly 10 to 100 years, whereas when humans add CO2 into the atmosphere at the rate we are, the natural cycle cannot keep up |
| What are the Hadley, Ferrell and polar cells? | three distinct atmospheric circulation cells that play a crucial role in Earth's weather patterns |
| Where does the Hadley cell control the weather? | Places around the equator |
| What effects do tropical cyclones have on people? | electricity lines damaged Houses destroyed |
| What effects do tropical cyclones have on the environemnt? | Trees are ripped up habitats are destroyed |
| Do cyclones need warm or cool water to form? | warm |
| What affect does altitude have on the temperature in the UK? | The temperature decreases the higher up you are in the UK, for example London is warmer than the mountains of Snowdon |
| Where does the UK usually get its North Atlantic drift from, where does it originate? | The Caribbean |
| What temperature air does polar and artic maritime bring to the UK? | Cold temperatures |
| Does air masses that travel over land bring wet or dry weather? | dry weather |
| Where and how does a depression begin to form? | When tropical maritime air meets polar maritime air over the Atlantic. |
| What is the leading front in a depression? | The warm front, brings light rain for long period |
| What does the synoptic code show us? | The weather station which includes: Temperature, wind speed, wind direction, cloud cover, weather conditions |
| What is the weather like in the summer? | Very little cloud, dry with light winds, risk of thunderstorms, early morning dew and mist |
| How do nutrients enter the soil in ecosystems? | rainwater and leaf litter |
| Where can rainforests be found? | Along the equator where temperatures are high and rain is plentiful |
| Which continents can rainforests be found in? | Asia, south America and Africa |
| Why do we cut down rainforests? | timber for building, land for agriculture, building human settlements |
| What is monoculture? | A type of agriculture in which only one crop is grown over very large areas of land |
| What are wild-life corridors? | Areas of land that allow natural habitats to thrive whilst inside human-controlled parts |
| What are debt-for-nature swaps? | Using money to help the rain forest instead of accumulating debt |
| What is the great green wall of africa? | An attempt to fight back against the Sahara desert by planting plants and trees that will stop the sand. |
| What are the benefits of the great green wall? | Increase biodiversity in the area, increase fodder for animals, reduce time people carry firewood |
| How do humans destroy natural environment in sand dunes? | People walk and cycle on the sand, meaning the marram sand is constantly being trod on and damaged, leaving the sand unprotected against strong winds |
| What are the environmental benefits of offshore wind farms? | No greenhouse emissions, reduce reliance of fossil fuels, turbine bases can act as reef bases for marine life |
| What are the environmental impact of offshore wind farms? | Noise during construction disturbing locals, construction will disturb sea bed, visual pollution, risk to sea birds if they fly into the blades |
| What is a tidal lagoon? | A man made wall that surrounds a part of a coast line, water flows in and out through turbines as the tide rises and falls |
