Index Progradation

In sedimentary geology and geomorphology, the term progradation refers to the growth of a river delta farther out into the sea over time. [1]

Aggradation

Aggradation (or alluviation) is the term used in geology for the increase in land elevation, typically in a river system, due to the deposition of sediment.

China

China, officially the People's Republic of China (PRC), is a unitary one-party sovereign state in East Asia and the world's most populous country, with a population of around /1e9 round 3 billion.

Erosion

In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it to another location (not to be confused with weathering which involves no movement).

Geoid

The geoid is the shape that the surface of the oceans would take under the influence of Earth's gravity and rotation alone, in the absence of other influences such as winds and tides.

Geomorphology

Geomorphology (from Ancient Greek: γῆ, gê, "earth"; μορφή, morphḗ, "form"; and λόγος, lógos, "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface.

Glacial period

A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances.

Ice age

An ice age is a period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.

Loess Plateau

The Loess Plateau, also known as the Huangtu Plateau, is a plateau located around the Wei River valley and the southern half of the Ordos Loop of the Yellow River in central China.

Marine regression

Marine regression is a geological process occurring when areas of submerged seafloor are exposed above the sea level.

Marine transgression

A marine transgression is a geologic event during which sea level rises relative to the land and the shoreline moves toward higher ground, resulting in flooding.

Mass balance

A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems.

Proglacial river

A proglacial river is a river that flows from the margin of a glacier.

Retrogradation

Retrogradation is the landward change in position of the front of a river delta with time.

River delta

A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water.

Sea level

Mean sea level (MSL) (often shortened to sea level) is an average level of the surface of one or more of Earth's oceans from which heights such as elevations may be measured.

New!!: Progradation and Sea level · See more »

Sea level rise

A sea level rise is an increase in global mean sea level as a result of an increase in the volume of water in the world’s oceans.

Seafloor spreading

Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Sediment

Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles.

New!!: Progradation and Sediment · See more »

Sediment transport

Sediment transport is the movement of solid particles (sediment), typically due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained.

New!!: Progradation and Sediment transport · See more »

Sedimentology

Sedimentology encompasses the study of modern sediments such as sand, silt, and clay, and the processes that result in their formation (erosion and weathering), transport, deposition and diagenesis.

Sequence stratigraphy

Sequence stratigraphy is a branch of geology that attempts to subdivide and link sedimentary deposits into unconformity bound units on a variety of scales and explain these stratigraphic units in terms of variations in sediment supply and variations in the rate of change in accommodation space (often associated with changes in relative sea level).

New!!: Progradation and Sequence stratigraphy · See more »

Stratigraphy

Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification).

New!!: Progradation and Stratigraphy · See more »

Subsidence

Subsidence is the motion of a surface (usually, the earth's surface) as it shifts downward relative to a datum such as sea level.

New!!: Progradation and Subsidence · See more »

Volume

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.

Yellow River

The Yellow River or Huang He is the second longest river in Asia, after the Yangtze River, and the sixth longest river system in the world at the estimated length of.
