6) to understand how rock fragments are transported by flowing
water or
wind,
and how grain size affects transport
and settling of sediment; understand how landscape can be
eroded.
However, once they die their test can be transported by
water,
wind and biological activity (other critters) to different
water depths, sometimes shallower, from that at which they lived
and are then deposited Moreover, foram tests are relatively robust, they survive in sediments
and so if earlier sediments are
eroded,
and the resulting sediment redeposited, any contained forams will be too.
