Answer:

becomes runoff and finds its way back to the ocean

Explanation:

Precipitation refers to rainfall that reaches the earth.

Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.

When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.

Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean

Which best explains why water is able to “stick” to the side of glass?
AveGali [126]

Explanation:

Adhesion means the ability to stick on the surface of another substance.

Water exhibits adhesive forces due to which it is able to stick to the glass.  Due to adhesive forces water spreads over the surface of glass and sticks to it.

These adhesive forces between the glass and water enough that it deforms the spherical shape of water molecules and help them stick to the surface of glass. As a result, adhesive forces overcome the repulsion between like molecules.

Hence, water is able to “stick” to the side of glass due to strong adhesive forces.

Which describes the amplitude of a wave when it carries more energy?
MrMuchimi

Answer:

It is higher.

Explanation:

The amplitude of a wave that carries more energy is usually higher.

The energy carried by a wave is related to the amplitude in such a manner that it is proportional to the square amplitude.

Amplitude is the maximum vertical displacement of a wave moving along its path.

  • Energy of wave and its amplitude are directly proportional to one another.
  • If the energy of wave is doubled, the amplitude is quadrupled.
  • So, the higher the energy of a wave, the more its amplitude.
