2 . The most considerable types of sedimentary rock are conglomerates. True or False?
three or more. The degree to which sediment debris become round depends on their hardness, what lengths they are moved, and the energy of their accidents with other debris. True or perhaps False?
four. Deep bodies of water are more effective in rolling sediment contaminants than quickly flowing estuaries and rivers. True or False?
