Earth's axis of rotation is almost parallel to the plane of its orbit. select the best answer from the choices provided t f

This is a false statement. So it is F

Explanation: The axis of the earth is an imaginary line. It makes an angle 66 1/2 degree with its orbital plane. So the earth is tilting with orbital plane, not in parallel position. The plane formed by the orbit is known as the orbital plane. Due to this tilting position the poles have 6 months day and 6 months night.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

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.
