Answer:
interests center around the physics and chemistry of the terrestrial planets, in particular, as it relates to their origin and early evolution.
Explanation:
polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.
Answer:As the Earth orbits the Sun, the tilt of Earth's axis stays lined up with the North Star. The North Pole is tilted towards the Sun and the Sun's rays strike the Northern Hemisphere more directly in summer. ... The tilt of Earth's axis points away from the Sun.
The answer is H—F. Fluorine is the most electronegative of the four halogens (and, in fact, of all the elements), so it does the best job of gathering the shared electrons to itself. Therefore, the bond with F is the most polar
