What is the similarity between mid-ocean ridges and accretion?

Mid-ocean ridges are the mountain ranges within the ocean environment. They are formed when oceanic plates collide during plate techtonics and magma rises above the oceanic lithosphere. Typically, it results into uplifting of the thin oceanic crust and making mountains. The magma solidify after interaction with the water and results into formation of new lithosphere.

Accretion is the phenomenon during which new material is added and landmass (lithosophere) is created during plate tectonics. Therefore, accretion takes place during formation of mid-oceanic ridges. Principally, when a plate subducts below the other plate, some material scrap off from the subducting plate and then deposit above the plate hence making accretionary wedge.

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.
