    Deposition (geology) Map of Cape Cod showing shores undergoing erosion (cliffed sections) in yellow, and shores characterized by marine deposition (barriers) in blue. [ 1] Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered ...

  3. Biogeography - Wikipedia

    en.wikipedia.org/wiki/Biogeography

    Biogeography is a synthetic science, related to geography, biology, soil science, geology, climatology, ecology and evolution. Some fundamental concepts in biogeography include: allopatric speciation – the splitting of a species by evolution of geographically isolated populations; evolution – change in genetic composition of a population

  4. Diagenesis - Wikipedia

    en.wikipedia.org/wiki/Diagenesis

    Diagenesis ( / ˌdaɪ.əˈdʒɛnəsɪs /) is the process that describes physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition. Increased pressure and temperature only start to play a role as sediments become buried much deeper in the Earth's crust. [ 1]

  5. Geobiology - Wikipedia

    en.wikipedia.org/wiki/Geobiology

    Geobiology employs molecular biology, environmental microbiology, organic geochemistry, and the geologic record to investigate the evolutionary interconnectedness of life and Earth. It attempts to understand how the Earth has changed since the origin of life and what it might have been like along the way.

    Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία ( -logía) 'study of, discourse') [ 1 ][ 2 ] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. [ 3 ]

  8. Natural history - Wikipedia

    en.wikipedia.org/wiki/Natural_history

    Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is called a naturalist or natural historian . Natural history encompasses scientific research but is not ...

  9. Sedimentation - Wikipedia

    en.wikipedia.org/wiki/Sedimentation

    v. t. e. Sedimentation is the deposition of sediments. [ 1] It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or ...
