For example, volcanic eruptions create islands, or when the Grand Canyon forms. I need one more example as to how the Earth is changing.

Here's a few:

Coastal erosion - the action of the waves destroys cliffs and change the shape of the country at the coast

Continental drift has a few different types of effect:

Collision of continental plates can cause mountain ranges. The Himalayas are caused by India colliding with Asia. And the Himalayas are still rising because of this

Rifts are caused by continental plates moving apart. The Rift Valley in Africa is an example of this. One day it will be part of the Red Sea. The movement of North and South America moving apart from Europe and Africa is also a rift (underwater in the middle of the Atlantic).

Changing atmosphere temperatures also affect sea levels which in turn affect coastlines. For example, during the last glacial period (when ice covered far more of the Northern Hemisphere) Britain was joined to France and there was no English Channel. This is recent enough for humans to have witnessed the change.

Erosion. Wind and rain and ice and thawing break up rocks over long periods of time and can turn dramatic mountains into soft, undulating hills.

These are just a few. Feel free to email me if you want more, or if you want more explanation of any of these.

Good question. Word up!
