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.

It is True, oxidation is associated with an increase in oxidation number.
An oxidation; reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Oxidation states are typically represented by integers which may be positive, zero, or negative.
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

Explanation:
Operant conditioning can be defined as an associative learning process which involves reinforcing the strength of a behavior. Thus, the outcome depends on the response in operant conditioning.
A reinforcement of a desired behavior involves the process of strengthening a positive behavior being exhibited by an individual through the use of stimulus. Therefore, making the behavior to be exhibited in the future by the individual.
1. Escape conditioning: A mosquito is biting your arm and you slap it. You are more likely to slap mosquitos biting your arm in future. An escape conditioning can be defined as a type of conditioning in which a subject such as a human learn how to avoid a stimulus that is aversive i.e the aversive stimulus is eliminated by the occurrence of the stimulus.
2. Avoidance conditioning: A mosquito is flying around you and so you slap it so that it does not bite you. You are more likely to slap at mosquitos flying around you in future. An avoidance conditioning can be defined as a type of conditioning in which the occurrence of the behavior prevents the aversive stimulus.
