* Abiotic: This refers to non-living components of an ecosystem. Rocks and water are not living things.

* Rock: A solid, naturally occurring mineral or mineraloid.

* Water: A vital component of all life, existing in liquid, solid (ice), and gaseous (water vapor) forms.

Examples of rock formations interacting with water in ecosystems:

* A river flowing over bedrock: The water erodes the rock, shaping the landscape and creating habitats for aquatic organisms.

* A cave system with a flowing underground stream: The water interacts with the limestone rock, creating unique formations and ecosystems.

* A coastline with rocky cliffs and crashing waves: The water continuously sculpts the rock, creating inlets, beaches, and tide pools.
