- 1cenzoic eraage of mammals
- 2glacier is a?large river of ice that forms on land and moves under the influence of gravity
- 3continental ice sheetvast expanse of ice which completely covers all underlying terrain. They form on land and spread outward in all directions.
- 4mountain glacierglacier that forms on a mountain at high elevations
- 5ice ageperiod during which ice sheets cover parts of the northern and southern hemispheres
- 6glaciationperiod during which polar ice sheets advance to cover large regions of north america and northern europe
- 7weatherthe state of atmosphere in variation
- 8climatethe average of daily and seasonal weather events that occur in a region over a long period of time
- 9causea phenomenon that brings about an effect
- 10correlationphenomenon that accompanies another
- 11probabilitya measure of how likely it is that an even will occur
- 12global conveyeris a constantly moving system of deep-ocean circulation driven by temperature and salinity. The great ocean conveyor moves water around the globe.
- 13hydrosphere greenhouse effectgreenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions.
- 14natural greenhouse effecteffect is a phenomenon created by gases naturally present in the atmosphere that affect the behaviour of the heat energy radiated by the sun/In simple terms, sunlight (shortwave radiation) passes through the atmosphere, and is absorbed by the Earth's surface
- 15enhanced greenhouse effectdisruption to the Earth’s climate equilibrium caused by increased concentrations of greenhouse gases has led to an increase in the global average surface temperatures
- 16milankovitch cyclesice sheets have advanced and retreated several times.repeated glaciations match changes in earths orbit around the sun and earths rotation on its axis
- 17drumlinstrangely shaped hill
- 18kamessteep-sided mound of sand melting ice sheets
- 19hoodoosa column or pinnacle of weathered rock
- 20sand dunea hill of sand built by wind or water flow
- 21formaniferaa group of organisms that lives in oceans around the world
- 22largest advancing ice sheetlaurentide ice sheet, west of hudsons bay
- 23worlds most powerful super computerearth simulator
- 24quaternary period was..a series of repeated glaciation and warming
- 25all the water on earths surface was contained in the..hydrosphere
- 26milankovitch found earths orbits in three ways. they are?1. shape of orbit
2. tilt of axis
3. wobble of the axis rotation - 27oceans have giant..converter currents that transport heat in the same way a fridge does
