Answer:
Marble is the correct answer.
Explanation:
Marble rocks forms when limestone undergoes metamorphism.
Marble rock is formed from the limestones,when the limestone is influenced by heat and tremendous pressure it transforms in marble through a method called metamorphism.
During the metamorphism, limestone gets recrystallizes and result in the formation of interlocking carbonate mineral crystals that form the marble.
Gravity keeps the water and yourself from falling off the planet into space.
