7. sediments originate from elements in seawater that precipitate out of solution. a. hydrogenous b. biogenous c. terrigenous d. turbidigeous

Correct answer choice is:

D. Hydrogenous

Sediments provide clues to unraveling the mysteries of Earth in the past. Hydrogenous sediments are created directly from the water of the sea or ocean. These are the precipitates of insoluble material, consisting of mainly rock and soil, which are taken from the land areas to the ocean by the means of wind and rivers

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

not too sure thinking all accelerations are pointed down
