B, false. It was mostly men seeking to explore west in search of riches, once those were obtained or the men were settled they brought back the women.
siliceous
Deep seafloor deposition in the form of ooze is the largest long-term sink of the oceanic silica cycle (6.3 ± 3.6 Tmol Si year−1). As noted above, this ooze is diagenetically transformed into lithospheric marine chert.
calcareous
Calcareous ooze is a calcium carbonate mud formed from the hard parts (tests) of the bodies of free-floating organisms. Once this mud has been deposited, it can be converted into stone by processes of compaction, cementation, and recrystallization. ... Foraminifera are also single-celled organisms.
