A current that runs parallel to the beach in the area where waves break is known as a longshore current. When waves hit a beach at an angle, longshore currents form. Longshore drift is the term for the transfer of silt by longshore currents.
Longshore drift is the flow of sediments along a coastline caused by waves that come in at an angle to the shore before reversing course and moving straight away. In a "sheet-like" arrangement, water in a longshore current moves up the beach before returning to the ocean. This sheet of water can carry beach sand back out to sea as it passes over and off the beach. As the longshore current sweeps down current, floating objects move up and down the beach in a zigzag manner.

Major shifts, that is shifts in the paradigms, are not very frequent - they would make scientific research unstable, as any result of a smaller study could be made invalid by a paradigm shift,
minor changes however are quite common - basically every scientific study adds to the common knowledge and this also can be considered a minor change.
Therefore the best answer is
<span>Major
shifts in scientific views very rarely occur, but minor modifications
of prior knowledge are continually made based on new research.</span>
Answer:
