<em>Answer:</em>
<em>Limestone is a type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO₃)₂.</em>
<em>Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feed stock for the production of lime, as a soil conditioner, and as a popular decorative .</em>
<em>Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) found in seawater to create their shells and bones.</em>
<em>LIMESTONE MEANING:</em>
<em>a rock that is formed chiefly by accumulation of organic remains (such as shells or coral), consists mainly of calcium carbonate, is extensively used in building, and yields lime when burned.</em>

Answer:
Man to man defense: the player follows and defends a specific player from the other team.
Zone defense: the player covers an area designed by the coach to defend it.
Explanation:
They are two ways of defense. Coaches use these defenses in sports such as handball, basket, or football, which are sports where the player has to invade areas and the game changes constantly.
In a man to man defense, also known as a player to player defense, the coach assigns to every player a rival to follow and defend. While in a zone defense, the coach gives each player an area to cover and protect during the game.
In both cases, the players can abandon their place or player if they feel that this will be better for the given situation in the game. It also makes it more dynamic and allows fluency in the game when there are failures in the defend.
