In order for a to form, the body must not be eaten or destroyed by erosion and other natural forces.

The correct blank is Fossil.

In order to form fossil, the body of the organism after death should not be eaten by the scavengers of the environment.

The body of the organism must not be eaten or destroyed and should be preserved in order to form a fossil.

It takes a long time for the formation of the fossil, if the body remains untouched for several years. The body of the organism is buried and compaction takes place. This creates impression of the animal and formation of fossil takes place.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
