Fragile ecosystems • climates (precipitation, temperature and wind) in cold environments vary considerably-mountainous to glacial • vegetation must adapt to these conditions . Why are cold environments considered as fragile the impact of climate and soils on the natural ecosystem the vulnerability of both flora and fauna to damage resulting from human factors, such as leisure activities, atmospheric pollution.

(15) 2 (c) using figure 4 and your own knowledge, explain why many cold environments are fragile and how they can be cared for to ensure sustainability (15) around the glacier in figure 2 (5) 01 (a) (ii) study figure 1 which shows the predicted return period of flood events for the river ouse at york.
Cold environments provide one of the last wilderness areas on earth and have fragile ecosystems economic development puts these ecosystems at serious risk of damage and therefore these areas need. All: identify why cold environment are fragile most: explain how cold environments can be harmed by economic development some: justify why cold environments need protecting.

A key stage 3 geography revision resource on extreme environments sub-topics include: what is an extreme environment, tropical rainforest ecosystems, why rainforests are important, deforestation. Cold environments as fragile environments cold environments such as western antarctica (including peninsula) and arctic tundra are extremely fragile, mainly due to the low. Extremely cold conditions and life is restricted to simple microorganisms glacial (alpine) environments found in mountain ranges and cover 5% of the earth's land surface.
Cold environments as fragile environments cold environments such as western antarctica (including peninsula) and arctic tundra are extremely fragile, mainly due to the low temperatures severely limiting vegetation growth and thus any development will destroy the natural environment. A fragile environment the tundra, because of its climate and limited productivity is considered to be a fragile environment there are a number of reasons for this. What are the issues associated with the development of cold environments cold environments provide opportunities and challenges for development.
The plants and animals are adapted to the cold conditions, so find it hard if their environment changes decay is slow because it's cold , so pollution is broken down very slowly tundra is a fragile ecosystem found in some cold environments eg in periglacial environments. Cold seep environments are an example of a unique deep sea habitat they differ from hydrothermal vent habitats found on mid-ocean ridges cold seeps usually occur along continental margins for example, in the gulf of mexico. - cold environments as fragile environments cold environments such as western antarctica (including peninsula) and arctic tundra are extremely fragile, mainly due to the low temperatures severely limiting vegetation growth and thus any development will destroy the natural environment. Designed for aqa as/a2 a'level specification includes lesson activities, presentation and assessment as well as sheets with prompts for students to annotate during the lesson.
Limited insolation=plants are limited in photosynthesis=lack of energy available=if destroyed can't be replaced (due to low npp and recovery rates)=leading to a high proportional impact. A fragile environment is a biome that is under threat from change, damage or unsustainable use most impacts will be long-lasting due to the inability of the area to recover easily due to extreme cold because things never decompose nor grow quickly. What does the future hold for these fragile, cold environments - describe strategies and methods used to reduce problems in cold environments include the use of technology, the role of governments, international agreements and conservation groups.
Working in cold environments also poses other risks such as work environmental risks of slippery floors and stairs health risks : exposure to cold environments can result in decreased blood circulation in the muscle tissue of the extremities (hands and feet) which can result in a reduction in staff's ability to function adequately. The tundra, because of its climate and limited productivity, is considered to be a fragile environment there are a number of reasons for this the slow rate of plant growth means that any disruption to the ecosystem takes a long time to be corrected. Many cold environments are extremely fragile and have fragile ecosystems in places such as the arctic national wildlife refuge, alaska this part of alaska is federal land, owned by the us, and contains high quantities of oil and gas.
