the idea that sediments spread out in all directions until they either thin out or run into a barrier can be explained by which of steno's principles?

a - principle of superposition

b - principle of original horizontality

c - principle of original lateral continuity

d - principle of faunal succession

answer:

the correct answer is c.

explanation:

the principle of horizontality faunal that sedimentary rocks are deposited in approximately horizontal layers. the principle of original lateral continuity states that sediments spread out in all directions until they either thin out or run into a barrier.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
