Final answer:
External forces that shape Earth's surface include weathering, erosion, deposition, and tectonic activity.
Step-by-step explanation:
The external forces that shape Earth's surface in the field of geography are known as geomorphic processes. These forces include weathering, erosion, deposition, and tectonic activity. Weathering involves the breakdown of rocks and minerals, while erosion refers to the transportation of rock fragments and sediment. Deposition occurs when sediment is deposited or laid down in a new location. Tectonic activity, such as earthquakes and volcanic eruptions, also play a significant role in shaping Earth's surface.
