The Earth's surface changes because of the Tectonic Plates beneath the crust.

Earth's Lithosphere is separated into several large and small pieces classified into divergent, transform, and convergent boundaries.

When these pieces collide, they cause frequent tremors in the Earth which may lead to eventual natural disasters such as earthquakes or floods.

Volcanoes, which can affect how the surface looks, usually erupt this way in convergent boundaries. Tectonic plates can also collide together, forming mountains and other such landforms.

Some plates can also pull away from each other, forming underwater ridges that spew out lava to the surface and eventual valleys in-land.

The last type of boundary is the transform boundary. They are called so because they rub against each other, side by side, which can be seen as slow mechanical erosion.

Together, these tectonic plates mend and shape the Earth. Land is created mostly by volcanoes and gradual shifts in the sea levels around the world, causing islands to form or secede underwater.

Humans also negatively contribute as we tend to deforest our lands for wood, but we benefit from doing so greatly. Dams are constructed to fill lakes up and maintain habitats for creatures in the environment and trees are planted to help prevent the extensive erosion of the soil.
