What is a example of carbon moving from the lithosphere to the hydrosphere?

As you probably know, the lithosphere is the ground (the solid Earth) and the hydrosphere is all the water on the planet and in the atmosphere as well.

When it rains, the rainfall hits cliff-faces and hills and takes with it some small material that has dissolved in the water. This is now in the hydrosphere and can be taken to the sea or a river leading to an ocean.
