Question

"#31 refers to the entire deep ocean floor, the ""Abyssal Plain" here we expect to find (choose all that apply)" fine dust blown from the continents O calcium carbonate deposits (the shells of calcium-fixing plankton) O water that is at the right conditions to dissolve calcium carbonate material silica-rich deposits below high productivity zones at the ocean surface sediment layers that increase in thickness and age away from the ridge

Answer 1
