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.

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.
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.
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.
The eye is considered an external organ because it is located on the surface of the body and is responsible for vision. However, it also contains internal structures, such as the retina and lens, that play crucial roles in processing visual information. Overall, while it has internal components, its primary classification is as an external organ.
External forces, such as weathering and erosion, shape surface landforms through the gradual breakdown and transportation of rocks and soil. Internal forces, like tectonic activity, produce landforms by causing uplift, folding, faulting, and volcanic eruptions that change the earth's crust. Both external and internal forces work together to create and modify the Earth's surface features over time.
Epithelial tissue is the type of tissue that always has a free surface exposed to the internal or external environment. This tissue serves as a protective barrier or lining for organs and cavities in the body.
Internal forces: tectonic plate movement, volcanic activity, and earthquakes. External forces: weathering, erosion by water/wind/ice, and impact events (e.g. meteorites).
An internal parasite feeds with his entire body inside the surface (epithelium, for animals) of the host, while an external parasite feeds with part of, or whole body standing outside the host's surface.
