No moraines are visible on the Kosciuszko map sheet but a number of glacial lakes occupy cirques along the Main Range. Find examples of each of these landforms on the map. The accumulation of ice and snow is affected by a number of factors additional to ordinary old temperature. High rates of supply can balance high rates of loss, producing extremely active temperate glacial systems such as those of the sub-Antarctic islands, New Zealand or northern Europe. Low rates of snow accumulation can be balanced by low rates of loss, a condition typical of polar glacial systems, such as those of Antarctica.
Topographic factors can also influence the local mass balance of ice bodies.
Explain your answer and assess the relevance of these observations to your estimates of changes in palaeotemperature.
