A blue line indicates that there is water running through the valley. If there is not a blue line the V pattern indicates which way water flows.
The greater the electronegativity difference, the moreionic<span> the </span>bond<span> is. </span>Bonds<span> that are partly </span>ionic<span> are called</span>polar<span> covalent </span>bonds<span>. </span>Nonpolar<span> covalent </span>bonds<span>, with equal sharing of the </span>bond<span> electrons, arise when the electronegativities of the two atoms are equal</span>
