Answer: B. Glaciers are thick sheets of recrystallized ice.
D. Glaciers last throughout the year.
Explanation:
A glacier is a continuously moving ice mass. It is formed over many years in regions where snow falls more quickly than it melts and evaporates. They are not stationary, but move due to their weight.
A high number of glaciers exist in mountainous regions but glaciers are not limited to these areas. They also do form on land.
Glaciers currently cover about 10% of our planet, down from the last Ice age when 32% of land was covered in ice.
