Abyssal plane: This refers to very fine muds and oozes that accumulate on the ocean floor in deep marine environments. These sediments often contain diatomaceous Earth and chert, with diatoms as the typical fossils

Reef: Reefs are lime mud deposits associated with coral growth. They are commonly found in marine environments and contain abundant coral fossils

Continental shelf: This area is part of the shallow marine environment. It includes the submerged portion of the continent, where sediments like sand, mud, and limestone accumulate

Alluvial fan: Alluvial fans form in terrestrial settings. They consist of poorly sorted sediments (from mud to boulders) deposited by braided meltwater streams


Braided meltwater stream: These streams occur in terrestrial (alpine) environments. They carry a mix of sand and gravel, creating braided patterns due to frequent channel shifting

Mudflat: Mudflats are found in shallow marine environments. They consist of mud and sand with channels, often showing mudcracks and symmetric ripples

Beach: Beaches are part of the littoral (shoreline) environment. They contain very well-sorted sand, and bioturbation (activity by organisms) is common

Delta: Deltas form at the end of river channels. They carry channelized sand with mud and may have swampy areas. Cross beds are often present

Meandering streams: These streams occur in terrestrial settings. They transport sand and mud, creating meandering patterns

Sand dunes: Sand dunes are aeolian (wind-driven) deposits found in deserts and coastal areas. They consist of well-sorted sand with large-scale cross-beds
