Which sediment is categorized under cosmogenous sediments?
a. Evaporites
b. Ooliths
c. Microtektites
d. Manganese nodules
ANS: C
Microtektites are a type of cosmogenous sediments. They are thought to form from violent impacts of
meteors and asteroids on Earth. The impact melts part of the crust on impact, causing it to splash back
into space. The material melts again as it travels back through the atmosphere before falling back to
Earth. The result is translucent, oblong sediments made of glass particles. Information can be found in
the section Sediments May be Classified by Source.
