Two tectonic plates of different densities collide. which of the following could form at the plate boundary? island mid-ocean ridge rift valley trench volcano

The correct answer is trench and volcano.

Explanation:

When two tectonic plates with distinct densities come into contact with each other because of the convection currents, which are generated by the heat inside the asthenosphere, a convergent plate boundary gets produced. The deep trenches are generally produced when one of the plates slides underneath each other, a procedure known as subduction. The plate that is underneath will move under the mantle, and there will be a discharging of fluids from the rock that will somewhat melt the mantle. The elevation of molten rock takes place and may erupt violently to generate volcanoes.

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.
