- Cold environments
- Categories of ice
- Valley Glacier- A mass of ice, moving slowly, enclosed by valley sides
- Ice Sheet- A mass of glacial land ice greater than 50,000km
- Ice Shelf- A thick, floating slab of ice that forms where a glacier or ice flows down a coastline
- Sea Ice- Frozen ocean water: it forms, grows and melts in the ocean
- Ice cap- A mass of glacial land ice covering less than 50,000km
- Why are they so cold?
- Latitude
- Poles are angled away from the sun, so winter darkness occurs
- Altitude
- Every 100m you go up, the temperature drops a degree
- Albedo effect
- The light colour of the ice reflects up to 80% of sunlight
- Continental effect
- Oceans are warmer in winter and cooler in summer, so inland areas are cooler in winter and warmer in summer
- Latitude
- Glaciation
- Snow that's been compressed into ice, flows downhill through plucking and abrasion
- Corrie- hollow formed by erosion, with a steep back wall and rock lip
- Arete- jagged ridge formed by two corries
- pyramidal peaks- where three corries are formed back to back
- glacial trough- when glaciers move, they turn v shaped valleys into troughs with ribbon lakes forming after the ice melts
- Use of cold environments
- Tourism
- Ski resorts
- Habitats destroyed to make way for facilities
- Seasonal jobs
- acid rain probability increase due to transport emissions
