Tropical rainforests and deforestation in Malaysia
Cards in this deck (23)
- 1where are tropical rainforests foundbig ones are in south east asia the small ones can be found in central america
- 2three things to describe rainforests climate60mm of rainfall a month
humid
around 30 degrees - 3are soils in TRF fertileyes
- 4how do soils in the trf fertile what is the soil left behind calledNo nutrients in the soil
- 5how does soil in a trf show an example of nutrient recyclingwarm climate gives a good habitat for decompsers
- 6what are epithyets how have they adapteda plant that grows on a tree to reach the top
- 7How have TRF adapted to heat and humidity? Give reference to the features of the leaves.leaves of trees are waxy and have drip tips which allow water to run off them in high rainfall. Leaves are angled so water does not collect on them.
- 8How have TRF adapted to competition for sunlight. Give reference to emergent trees.It has four layers, each layer adapts to its conditions. Emergent trees (Kapok) grow upwards very quickly. They have tall slender trunks over 40 m high. Parasitic plants attach to host trees for food and water supply.
- 9What is deforestation?Cutting down of trees on a large scale
- 10Two facts that show the scale of deforestation.62 counties with TRF. UN estimates that about 50% of world TRF have now been cleared. in Malaysia it is increases faster than anywhere else.
- 11Give the name of a country that experiences high rates of deforestation.Malyaysia
- 12Rate of deforestation is increasing faster in Malaysia than any other developing country give a fact that supports this.Area larger than Denmark has been lost since 2000.
- 13What are the 6 main reasons for deforestation in Malaysia?1. Mineral extraction (gold and copper
2. Population pressure (transmigration)
3. Commercial farming, eg palm oil
4.Subsistence farming eg use flash and burn to clear forest.
5. Energy development
6. Logging - 14Explain why mining leads to deforestation in Malaysia?Drilling for oil and gas in Borneo
Gold and copper extraction. - 15Explain why population pressure leads to deforestation in MalaysiaPoor urban people moving to the forest. Transmigration.
- 16Explain why commercial farming leads to deforestation in MayaysiaBiggest exporter of palm oil, produces 85% of the worlds palm oil
- 17Explain why subsistence farming leads to deforestation in MalaysiaTribal people living in TRF practice it. Slash and burn to clear the land, the fires can get out of control and burn more forest than they want.
- 18Explain why energy development leads to deforestation in malaysiaLarge Dams built to prodcuce hydro electric power. ~The dams reservior flooded of 700 km of forest and farmland.
- 19Explain why logging leads to deforestation in MayalsiaLogging involves large areas of forest being cleared. To access teak and mahogany to make furniture.
- 20What are the four impacts of deforestation in MalaysiaSoil erosion
Loss of biodiversity destroys the ecosystem
contributes to climate change
loss of habitat for wildlife - 21Give a specific example of loss of biodiversity as a result of deforestation in MalaysiaOil palm plantations isolate populations of orang-utans which threatens their survival.
- 22How does deforestation affect the climateTrees give of moisture by process of transpiration, deforestation reduces the moisture in the air resulting in a drier climate. Less trees = less evaporation which causes temperature rise.
