Answer: Positive
Explanation: During the winter, snowfall increases on a glacier, which causes accumulation and thickening of the glacier. Because there is not much melting during this time, it results in a net gain of ice on the glacier. This is referred to as a positive ice budget because the glacier is gaining more ice than it is losing. The opposite of a positive ice budget is a negative ice budget, which occurs when a glacier is losing more ice than it is gaining. This can happen due to factors such as increased melting or calving (the breaking off of chunks of ice from the glacier's edge).
