Sediments with an extraterrestrial origin are those that have been deposited on Earth from outer space. This can include materials such as meteorites, cosmic dust, and tektites. These sediments provide valuable insights into the history and composition of our solar system.
Glacial drift is the term for all sediments of glacier origin.
Glacial deposits or glacial drift refer to all sediments of glacial origin. These deposits include materials such as till, moraines, outwash plains, and glacial erratics that are left behind by the movement of glaciers.
The heaviest sediment is generally composed of materials such as gravel, sand, and silt. These sediments have higher densities and larger particle sizes compared to lighter sediments like clay. Heavy sediments are typically found closer to their source of origin due to their weight.
Extraterrestrial rock is rock that did not originate from Earth.
Sedimentary rocks form from the accumulation and cementation of sediments such as sand, silt, and clay. These sediments are typically eroded from pre-existing rocks and transported by water, wind, or ice before being deposited and lithified into sedimentary rock over time.
