How does the surface of the earth change?

Answer 1

The shape of the earth can change in several ways.

First is tectonic plate movement, which is the movement of the land masses the continents reside on, over the period of millions of years. Tectonic movement is very slow and gradual, occurring only millimeters or inches at a time, which is one of the causes of earthquakes.

The second way the earth changes shape is very subtle, through the influences of gravity by outside stellar bodies such as the moon. This can create a "bulge" on the side of the planet facing the interstellar body, but this is so small that the effect of gravity on water is more clearly noticed (which is responsible for the tides).

The third is from massive space-based impacts such as meteors or comets, which only cause minor changes in the earth's shape (which are typically only topographical).

The fourth is the spin of the earth itself, which causes the horizontal (equatorial) section of the earth to be slightly wider in diameter than it's vertical (north-south) section, resulting in a planet which is not entirely spherical shaped. However, since the earth's spin essentially does not change, and it would take a substantial shift in the earth's rate of spin to cause it's "bulge" to grow or shrink, this isn't really a possibility.

Answer 2

The surface of the Earth changes through processes such as erosion, weathering, plate tectonics, and human activities. Erosion and weathering wear down rocks and landforms over time, while plate tectonics cause landforms to shift and change. Human activities, such as mining and construction, also impact the Earth's surface.

Answer 3

yes the earths surface does change when theres a earthquake or a tornado or something like that

Answer 4

Yes earth is constantly changing because people are multiplying their self and the world will be full of people and less animals to live.
