Broken Fragments
Continental sediments are those which are found: on the ocean floor, on land masses or both?
Land Masses...desserts, lakes, streams, glaciers etc.
Chemical sediments form by:
Shallow lakes, lagoon evaporation, or precipitation from a solution
The three main types of sedimentary environments are:
Enviroments of deposition

Transitional or intermediate environments...deltas, lagoons, beaches

Continental Environments
List two transitional environments:
Lagoons

tidal Swamps

Deltas
What is a chemnical sedimentary rock?
