SteveThe three internal forces in the Earth are mantle convection, gravity, and radioactive decay. Mantle convection drives the movement of tectonic plates, gravity affects mass distribution and generates stress in the crust, and radioactive decay produces heat that contributes to the Earth's internal energy.

Are earthquakes internal or external forces of change?
Earthquakes are internal forces of change caused by tectonic plate movement and stress release along faults within the Earth's crust. They are not considered external forces as they originate from within the Earth.
Is a mountain formed by internal or external forces?
A mountain is formed by both internal and external forces. Internal forces, such as tectonic plate movement and volcanic activity, cause the uplift of the Earth's crust. External forces, such as erosion by wind, water, and ice, shape the mountain's surface over time.
What are the 3 external forces in the Earth?
The 3 external forces acting on Earth are gravity from the Sun and Moon, solar radiation pressure, and tidal forces from the Moon and Sun.
What is a feature sculpted on earths surface by internal or external forces?
Mountains are a feature sculpted on Earth's surface by internal forces such as tectonic plate movements or external forces like erosion from wind and water. They are formed when the Earth's crust is pushed together or pulled apart, resulting in uplifted landforms with peaks and valleys.
How do internal forces of change effect earths surface differently from external forces of change?
Internal forces of change, like tectonic plate movement, can lead to large-scale changes on Earth's surface such as mountain formation, earthquakes, and volcanic eruptions. In contrast, external forces of change, such as erosion by wind and water, shape the surface through processes like weathering and sediment transport. Both internal and external forces play complementary roles in shaping and transforming Earth's surface over time.
