c. sandstone
d. marble
The correct answer is option D - Marble.
The marble is a metamorphic rock that forms when limestone is under the heat and pressure of metamorphism. It is composed mainly of the mineral Calcite and it generally contains other minerals such as quartz, graphite, micas, etc.
Besides, the characteristics swirls of the colored marbles varieties are usually the result of the mixture of various mineral impurities such as sand or iron oxides.
Marble is commonly used as a building material and for sculpture.
Marble is a metamorphic rock formed from limestone through the process of metamorphism, resulting in its distinctive appearance and properties. The correct option is d. Marble.
Marble is a metamorphic rock formed from limestone. The process of forming marble involves the metamorphism of limestone, which is a sedimentary rock composed primarily of calcite or dolomite minerals. When limestone undergoes metamorphism due to heat and pressure deep within the Earth's crust, it undergoes a transformation.
During this process, the calcite or dolomite crystals in the limestone recrystallize and grow, resulting in the formation of marble. Marble typically has a distinctive appearance with a crystalline texture and a wide range of colors and patterns, depending on the impurities present in the original limestone and the specific conditions of metamorphism.
Marble is widely recognized for its use in, architecture, and decorative elements due to its beauty and unique veining patterns. It is a valuable and sought-after natural stone in the construction and art industries.
So, the correct option is d. marble, which is indeed a metamorphic rock formed from limestone through the process of metamorphism.

Answer:
Intertidal zone
Explanation:
The intertidal zone is the area which in low tide is above the water and at high tide below the water.
The area lying beyond the continental shelf is called the open-ocean zone.
The area lying just above the continental shelf is called the neritic zone.
An estuary is a coastal body which is located at the point where rivers merges with the ocean.
Hence, the intertidal zone is being discussed in the question.
