The correct answer is option D, that is, ice floating on the water surface.
The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.
The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.
The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.

Answer:
Faunal succession
cross-cutting relationships
superposition
Explanation:
Relative dating helps determine geological events by observing rocks.
Faunal succession is a method that uses sedimentary rocks for dating by observing the plant and animal fossils in them.
Cross-cutting relationships show that the layer that cuts across other layers are younger than the layers that they cut through.
Superposition states that younger layers are formed on top of the older layers. So if you are looking at the layers beneath the Earth, the ones that are in the bottom are older and as time pass younger layers form on top of them.
Western Honey Bee: They Pollinate The Earth by spreading Pollen around that has latched onto their feet while they took a walk on the flower head. Bull Frog: Eats flies, lays eggs, lowers the amount of insects near the area, increases the population of bullfrogs. Homo Sapiens Epoch 74 ( humans ) : Pollute the earth, kill animals, make a mess, overpopulate the world, leaves barely any room for animals. Hamsters: Digs holes in the ground, eats seeds, poops everywhere, sometimes eats bugs.
