Question 5

Explain how glaciated and periglacial landscapes play an important role in the maintenance of the natural carbon cycle

Explain the role of positive feedback

Answer 5

Is a large carbon sink, more carbon is added then lost
Stores carbon and methane preventing these gases being released into the atmosphere.

A loss of snow/ice cover leads to decreased surface albedo leading to further global warming, amplification

Question 6

Explain how glaciated and periglacial landscapes play an important role in the maintenance of the biosphere (animal migration)

Answer 6

Is an important part of ecology as species health depends on migration
Species migrate North to periglacial landscapes as a summer home to breed and then south in the winter. Play an important role in food webs

Question 7

Explain how glaciated and periglacial landscapes play an important role in the maintenance of the climate system

Answer 7

Contribute towards global refrigeration.
The heat deficit of polar regions is balanced by atmospheric circulation and thermohaline circulation, moving heat towards the poles.
High albedo of landscapes surfaces reflects 90% of solar energy back into space.
Cooling effect on planet, regulating global temperatures

Question 8

Explain how glaciated and periglacial landscapes play an important role in the maintenance of the water cycle

Answer 8

Glaciated landscapes hold global ice volumes , if they melted sea levels would rise and cities like London and New York would go underwater
Periglacial landscapes thaw in summer and gradually release meltwater , a critical component in human water supply

Question 9

Explain how Avalanches are formed

How are they natural hazards which threat glaciated landscapes
Exemplification

Answer 9

An avalanche exists when stress exceeds strength of snow located on a slope
Results from two types of snow pack failure:
Loose snow which acts like dry sand, small amount slips out of place and then moves down slope
Slab avalanches: occurs when a layer of snow breaks away from a wel underlying layer

Avalanches path can be predicted but can cause a hazard due to their size, an avalanche in Peru killed 18000 people in 1970

Question 10

Explain how Lahars are formed

How is it a natural hazard for glaciated landscapes
Exemplification

Answer 10

Question 11

Explain how glacial outburst floods (Jökulhlaup) are formed

How are they a natural hazard (Exemplification)

Answer 11

Is a powerful flood caused by the sudden discharge of a subglacial or ice moraine dammed lake behind a moraine obstruction
Glacial outbursts can be triggered by:
Increased flotation of ice as water levels rise
Overflow and melting of an ice dam by CC or tectonic activity
Overtopping caused by a avalanche or landslide
Melting of ice within moraine and removal of fine sediment in moraine

Is a threat to areas tens to hundreds of kilometres away from its source , destroying properties, especially in the Alps

Reduces the ecosystem balance, disrupts the food chain and leads to the endangering of species

In Antartica bird species were cut in nets for fishing and drowned

Question 22

Explain how construction is a human threat to glaciated landscapes

Answer 22

Involves infrastructure, hotels and ski lifts which disrupt the natural migratory patterns and lead to noise pollution. Removal of natural vegetation takes place reducing the natural protection from avalanches and glacial outbursts.

Question 23

Explain how resource exploitation is a human threat to glaciated landscapes

Exemplification

Answer 23

Exploitation of metals, fossil fuels and minerals fuels the melting of ice , leading to rising sea levels and destroying of habitats

Companies from the USA , Russia and Norway are trying to drill into areas of melting ice in the Artic to extract large stores of natural gas and oil

Question 24

Why are rising global temperatures the biggest threat to ice masses

Answer 24

Higher temperatures lead to a negative mass balance and shrinking glaciers, ice caps and Ice sheets

Periglacial areas will experience melting permafrost and dramatic changes to the ecosystem and biodiversity of the tundra

Question 25

What is the current condition of the worlds glaciers Exemplification

Answer 25

The majority of the worlds glaciers are retreating 95% of Himalayan glaciers are in rapid retreat Areas in Peru and Bolivia covered by glaciers shrank by 25% over the last 30 years

Question 26

What are the consequences of global warming on the hydrological cycle (5) Exemplification

Answer 26

Will reduce water supply to rivers - western china has 350 million farmers dependent on water supplied from the shrinking Tibetan plateau Increased flood risk if summer ice melt increases, increases river discharge Low meltwater levels limit HEP dam operation Low meltwater levels fail to flush rivers clean, leads to high water pollution and lower water quality Changes in sediment yield of glacial meltwater streams
