Which of the following statements is true? The crust below the continents is made of basalt and salt sediment.

According to continental drift theory, the continents used to be joined together.

The crust below the continents is thinner than the crust below the ocean.

The Earth's tilted axis is the main reason for day and night.

the most logical answer would be a

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.
