It has changed by Volcanoes,Earthquakes,Hurricanes,Tornadoes,Floods, and Tsunamis. Earth also has plates that move to make Earthquakes. It will change in the Future, because it is a Mystery.
The earth's surface changed a bit in the past the continents used to all be one called PANGAEA but over time the plates have separated and are as we know them today
