Which statement is true about the Earth’s oceans? a. They are all getting larger due to the movement of tectonic plates. b. They have changed over time. c. They have not changed in 4 billion years. d. They are all getting smaller due to the movement of tectonic plates. Please select the best answer from the choices provided A B C D

b

Explanation:

earth's ocean did  grew higher over time because o rainfall for the last 20 years!

B :)

Explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

so whats the answer
