How can we measure the rate of seafloor spreading?

Measure from a spot at which the plate is spreading outward to a spot with a known age point. Use the map's scale to convert the measurement into actual inches of spreading over that time period. Divide the distance the sea floor spread by the time it took to spread that far, to find the rate of spreading per year.

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.
