The top layer of rock and soil which contains both air and water is called the soil.

Here's why:

* Soil is the uppermost layer of Earth's crust that supports plant life. It's made up of weathered rock, organic matter, air, and water.

* Air fills the spaces between soil particles, allowing for gas exchange.

* Water is held within the soil, providing moisture for plants and supporting a variety of living organisms.
