A bioturbator is an organism which carries out bioturbation - the mixing of soil or sediment by living organisms.
A bioturbation is a process of mixing of soil or sediment by living organisms.
Bioturbation refers to the reworking and mixing of sediments due to biologic activity. Worms and other burrowing organisms are common producers of bioturbated sediments.

A biotransfer is a form of bioturbation - the transfer of material by living organisms.

They are important in soil bioturbation, sediment porosity and ground water movement.
Geological bioturbation is the process where organisms, such as burrowing animals or bottom-dwelling organisms, disturb and mix sediments in the Earth's crust. This activity can create structures and patterns in the sediment layers, influencing the distribution and composition of rocks and minerals. It plays an important role in sedimentary processes and can provide insights into past environmental conditions.

Worms play the most important part in our ecosystem. They clean it up and do the natural recycling. They eat the left over organic material and make the soil fertile. The pathways created when they move help the soil breath and drink. Worms help the air and water to get in to the soil and this helps plants grow because there is more of a chance that the plants root can get more oxygen and water. -Cory Scott
The landscape can be worn away through various processes such as weathering and erosion. Weathering involves the breakdown of rocks into smaller pieces by physical or chemical means. Erosion then occurs when these weathered materials are moved and transported by natural agents like water, wind, or ice. Over time, these processes can shape and reshape the Earth's surface, creating features like valleys, canyons, and coastlines.
The processes for mechanical weathering are what change the rock completely. In chemical, it's what changes the rock into something different.For mechanical, there are four types of weathering.1) Abrasion: Sand and rock particles are carried by wind, water or ice and wear away exposed rock surfaces.2) Exfoliation: (heating and cooling of the rock)3) Bioturbation: * roots of trees and other plants enter cracks in rocks and eventually break them. * An animal that burrows in the ground.4) Frost action/ ice wedging: When water enters a rock and freezes which makes the rock expand and therefore, make the crack bigger. (Think of this like snow and ice and the side walks.)
