What is plastic flow
300
Glaciers are masses of ice that flow under the influence of _____.
What is gravity
300
Caused by friction at sides and bottom of ice mass and by warming during the summer months
What is melting
300
Formed by the merging of valley glaciers, these glaciers are always less than 50,000 km²
