Energy fluctuates within narrow limits
Sediments derived from volcanoes are
Terrigenous to
Sediments are called oozes when they contain at least
30% biogenous sediments I
Below the CCDS sediment composed of
Calcium carbonate will dissolve
Small glassy translucent particles found in sediments and thought to be of extraterrestrial origin are
Tektites
