Document Summary
Climate long term average of day to day weather: can be described in terms of temporal distribution & variability in amount of precipitation, wind speed, range of temperature & relative humidity. Shut down of heat transfer: glaciers advanced & destroyed homes in alps, crop failure. End of viking settlement in greenland & newfoundland. Paleoclimate proxy records: records that are a proxy/substitution for change in climate. Landforms (indicate ela depression >100m during lia: athabasca glacier retreat since end of lia. Lake & marine sediment cores: stratigraphy & composition of marine/lake sediment cores can be used to decipher changes in climate & differences in geomorphic processes & their rate over time. 5: terraces bench-like landforms incised into alluvium or bedrock by a stream during degradation (alluvial or strath terrace, rejuvenated stream energy leads to increased erosion of old floodplains. Landscape response: at end of this glaciation, local sea level in strait of.
