Question

1. what is a major outcome of glacial movements during the ice age?

a. formation of volcanic islands

b. formation of coastal cliffs

c. creation of river deltas

d. shaping of deep valleys and lakes

Explanation:

• Option a: Volcanic islands form from volcanic activity, not glacial movement.
• Option b: Coastal cliffs are formed by erosion from waves, not glaciers.
• Option c: River deltas are formed by sediment deposition from rivers, not glaciers.
• Option d: Glacial movement (erosion and deposition) shapes deep valleys (like U - shaped valleys) and creates lakes (e.g., glacial lakes formed by glacial erosion or deposition blocking water flow).

Answer:

d. Shaping of deep valleys and lakes
