Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
The correct answer is option A, that is, the Earth is spinning on its axis.
The westerlies refer to the prevailing winds that blow from the west to the east in the mid-latitudes, that is, in between 10 and 60 degrees. The wind blows from the regions of higher pressure to the region of lower pressure, but it does not blow in a straight line.
This is generally because the Earth is rotating on its axis. The spin of the Earth makes winds to bend towards the right in the northern hemisphere and towards the left in the southern hemisphere. This is known as the Coriolis effect.
