Question

a force that pulls water up, slowing its downward movement is
a. capillary action
b. gravity
c. porosity
d. permeability

Explanation:

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. It can pull water up. Gravity pulls water down. Porosity refers to the amount of pore - space in a material and permeability is the ability of a material to allow fluids to pass through it. Neither porosity nor permeability are forces that pull water up.

Answer:

A. capillary action
