PROS: It dissolves in water and lowers the freezing point of water so a lower temperature is required for ice to form. This makes the road less treacherous for vehicles. Road salt is usually cheap and readily available. Since salt is already a constituent of sea water, it does not cause pollution when washed away.
CONS: Salt dissolved in water is corrosive to metal. A metalled road surface may eventually be attacked by the corrosive, leading to damage of the surface. The salt solution is splashed on to the bodies and into the engine parts of vehicles and, unless properly protected, the metal parts of the vehicle will become corroded. Salt solution is a good conductor of electricity so it could under certain circumstances affect the electrical circuits within vehicles. When the salt solution dries out it leaves a deposit of white salt on the surface. The spreading of road salt is often carried out by specially equipped vehicles, so there is a cost incurred in salt spreading. Usually salt is mixed with grit.

Answer:
D. A hurricane carries ocean water across the coast and damages houses of people.
Explanation:
This question is looking for a statement that shows the interaction of an atmosphere, hydrosphere and biosphere. Firstly, atmosphere refers to the layer of the air that surrounds the earth i.e it pertains to air. Hydrosphere refers to the part of the earth occupied by water bodies e.g sea, river, ocean etc. i.e. it pertains to water.
Biosphere is the part of the earth that has to do with life i.e. it pertains to living organisms e.g plant, animal, human etc.
Based on the definition of each component, option D truly shows the relationship/interaction of the three components mentioned. That is, A hurricane (represent part of the atmosphere because it has to do with air) carries ocean water (represents hydrosphere because it involves water body) across the coast and damages houses of people (represents biosphere because it talks about living humans).
Little confused on the question but if I am suppose to match the question with one of the statements I would choose that
“The cell membrane pinches in to form two new cells.” - what happens during cytokinesis.
Thank you I appreciate it
