Explanation:
Earthquakes are common in regions within a convergent tectonic plate boundary. This kind of boundary involves collisions between two tectonic plates. Usually the less dense plate (usually the continental) is subducted underneath the more dense (usually the oceanic) plate. This is great friction between the plates due to their rugged nature. Usually, they get stuck and when they suddenly release, the energy is dissipated an earthquake.
An ionic bond is formed by the transfer of electrons from one atom to the other. It is usually formed between a metal + non-metal.
A covalent bond is formed by sharing of electrons between two atoms. It is formed between two nonmetals. A polar covalent bond is formed between 2 non-metals which differ in their electronegativities. In contrast, in a non-polar covalent interaction the two atoms could either be the same or have very close electronegativities.
1) P and I : Both non-metals with different electronegativities= Polar Covalent
2) Fe and O: Metal + non-metal = Ionic
3) S and Cl: Both non-metals with different electronegativities= Polar Covalent
4) S and S: Both non-metals and the same atoms = Non-polar Covalent
5) Br and Br: Both non-metals and the same atoms = Non-polar Covalent
6) O and Cl: Both non-metals with different electronegativities= Polar Covalent
7) Be and Cl: Metal + non-metal = Ionic
8) Al and N: Metal + non-metal = Ionic
Answer: Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
It's impossible for it to be summer and winter in the same hemisphere because the southern and northern hemispheres have their seasons inverted. For example; when it is summer in the US it is winter in Australia.
Hope this helps :)

Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies.
The electronic configuration for given elements is as follows:
