"ucture and properties of Matter
lapo4ka [179]

Answer:

Covalent bonds form when two atoms share valence electrons,

while Van der Waals forces cause an attraction between nonpolar

molecules

Explanation:

A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.

Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

How are convection current in the mantle and in the oceans similar? How are they different?
Vanyuwa [196]

Hello,


Convection currents in the mantle and in the ocean are similar because they both are responsible for the shaping the Earth's surface. Two forces are behind the movement of Earth's huge land masses. Those forces are convection and gravity.


Convection describes the movement of gasses or liquids due to different temperatures. The convection currents just beneath Earth's crust flow very slowly, causing movement in the plates above them. These currents are different with the fact that they produce different plate movements. Ridge push occurs from the convection currents in the ocean. These occur at mid-ocean ridges, which are elevated higher than the rest of the ocean floor. In contrary, convection causes material in the mantle to flow. Due to combined action of convection currents and gravity, Earth's plates are in constant motion.
