العوامل الخارجية لتشكيل سطح الأرض.

The video explains the factors affecting the Earth's surface, divided into internal and external categories. Internal factors were previously discussed, while external factors include water, wind, and ice. Water causes erosion, forming floodplains and deltas. Wind shapes desert landscapes through erosion, creating sand dunes. Ice, through glacial processes, forms ice sheets and glacial lakes. The video concludes by summarizing these factors.

What are the two main types of factors that influence the formation of the Earth's surface?

• Biological and chemical factors

• Natural and artificial factors

• Internal and external factors

• Physical and chemical factors

Which process is responsible for the formation of floodplains and river deltas?

How does wind contribute to shaping desert landscapes?

• By creating river deltas

• By eroding and transporting sand

• By melting ice caps

• By causing volcanic eruptions

What is the result of wind erosion in desert areas?

• Creation of sand dunes and depressions

• Emergence of volcanic mountains

• Formation of glaciers
