27
What is a cold environment?
A cold environment is characterized by low temperatures and often includes regions such as polar areas and high altitudes.
28
Where are cold environments found around the world?
Cold environments are found in polar regions, high mountain ranges, and certain continental interiors.
29
What are at least 4 cold environments?
1. Antarctica 2. Arctic regions 3. Greenland 4. The Himalayas
30
How does altitude impact the location of cold environments?
Higher altitudes typically have lower temperatures, contributing to the presence of cold environments.
31
How does latitude impact the location of cold environments?
Cold environments are often found at higher latitudes where sunlight is less direct.
32
How does continentality impact the location of cold environments?
Continental areas can experience extreme temperatures, leading to cold environments away from the moderating influence of oceans.
33
What are glacial budgets?
Glacial budgets refer to the balance between accumulation and ablation (melting) of glaciers.
34
How do glacial budgets impact rates of erosion and the movement of ice?
An advancing glacier can increase erosion rates, while a retreating glacier may slow down ice movement.
35
What are the processes of erosion?
The main processes of erosion include plucking and abrasion.
36
What are the processes of weathering?
Freeze-thaw is a common process of weathering in cold environments.
37
How does erosion and weathering create a corrie?
Erosion and weathering shape a corrie by removing material from the landscape, often creating a bowl-shaped depression.
38
What are U-shaped valleys?
U-shaped valleys are formed by glacial erosion and have a characteristic U shape, contrasting with V-shaped river valleys.
39
How are U-shaped valleys formed?
U-shaped valleys are formed by the movement of glaciers that carve out the landscape.
40
What is life without ice?
Ice melting impacts ecosystems, sea levels, and human populations.
41
What is the evidence that the global climate is changing?
Evidence includes rising temperatures, melting ice caps, and changing weather patterns.
42
Why is our climate changing? Explain the role of the human enhanced greenhouse effect.
Human activities increase greenhouse gas emissions, enhancing the natural greenhouse effect and leading to global warming.
43
Why is our climate changing? Explain the role of the carbon cycle.
The carbon cycle is disrupted by human activities, leading to increased carbon dioxide levels in the atmosphere.
44
Who is to blame for climate change?
Key contributors include industrialized nations, corporations, and individuals with high carbon footprints.
45
What are the consequences of climate change for the UK?
Consequences include increased flooding, rising sea levels, and changes in weather patterns.
46
What are the consequences of climate change for the Maldives?
The Maldives face rising sea levels, threatening their low-lying islands and freshwater supplies.
47
How can homes be made more sustainable?
BedZED is an example of a sustainable community that incorporates energy-efficient designs.
48
What are the costs and benefits of renewable energy sources?
Costs include initial investment, while benefits include reduced emissions and sustainable energy supply.
49
What are examples of renewable energy resources?
Examples include solar, wind, hydroelectric, and geothermal energy.
50
What is the Swansea Bay tidal lagoon case study?
It is a project that aims to harness tidal energy for sustainable electricity generation.
51
What are the parts of a drainage basin?
Key parts include source, confluence, tributary, watershed, mouth, and drainage basin.
52
What are the key river processes?
The key river processes are erosion, transportation, and deposition.
53
How does a river change from the upper to lower course?
In the upper course, rivers are steeper and faster, while in the lower course, they are wider and slower.
54
What are map skills for identifying glacial and river landscapes?
Skills include using 4, 6 figure grid referencing, compass directions, height above sea level (contour lines), and map keys.
