the end of a valley glacier is at a lower elevation than its point of origin is. how does this help explain melting at its end while snow and ice are still accumulating where it originated

glacier is a large accumulation of many years of snow, transformed into ice. This solid crystalline material deforms (changes) and moves.
Glaciers, also known as "rivers of ice," actually flow. Gravity is the cause of glacier motion; the ice slowly flows and  eforms (changes) in response to gravity.
A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster.
Rock that falls onto the glacier's surface is incorporated into the glacier and erodes the bed, forming sediment. The glacier and its load of rock debris flow down-valley.
A glacier discharges snow from its accumulation area in the same way a stream discharges water from its watershed.
Sometimes, in cold climates with a lot of snow, like Alaska, glaciers flow all the way down to sea level. These glaciers carve fjords and make icebergs.
At the glacier's face, ice which has been melting, fracturing, and has been battered by the sea breaks off as icebergs - a process, called calving, that balances the flow of ice from behind.
