Which of the following best describes the behavior of nonconservative elements in seawater? A. Nonconservative elements are reactive in seawater and have a long residence time.
B. Nonconservative elements are reactive in seawater and have a short residence time.
C. Nonconservative elements are non-reactive in seawater and have a short residence time.
D. Nonconservative elements are non-reactive in seawater and have a long residence time.

B. Nonconservative elements are reactive in seawater and have a short residence time.

Explanation: The non-conservative elements of seawater possess two paramount properties which include being chemically or biologically reactive as they are usually dependent on seasonal or short geological cycles. They also posses short residence time, which is the measure of the average time a dissolved substance spends in seawater. They also have varying concentration Ober time. Examples of nonconservative elements include; Iron and Carbon.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
