LaoSeveral factors can lead to changes in a planet's surface, including geological activity such as tectonic movements, volcanic eruptions, and erosion by wind, water, or ice. Impact events like asteroid strikes can also cause significant alterations to the terrain. Additionally, human activities such as mining and deforestation can impact a planet's surface.

Which of the outer planets has a surface more similar to the inner planets than to the outer planets?
Neptune has a surface more similar to the inner planets than to the other outer planets. It is primarily composed of rock and ice, similar to the composition of the inner planets, whereas the other outer planets are predominantly gas giants.
What is the force of gravity at the surface of the eight planets called?
The force of gravity at the surface of the eight planets is called surface gravity. It is the gravitational pull experienced by objects on the surface of a planet due to its mass.
Why do planets that are the same size have different surface area?
Two planets of the same size can have different surface areas due to variations in their topography, such as mountains or valleys. The presence of oceans or atmospheres can also affect surface area. Additionally, geological activity can constantly change the surface area of a planet over time.
Do planets change position during each season and when do they change for each season?
Yes, planets do change position during each season. The position of planets changes due to the Earth's orbit around the Sun, causing different planets to be visible at different times of the year. The change in position of planets varies depending on the planet and the season.
Which planet has the highest surface gravity of the terrestrial planets?
Mercury has the highest surface gravity of the terrestrial planets. Its gravity is about 0.38 times that of Earth's gravity.
