Which of the following causes tornadoesa. wind shearb. stationary frontsc. dry climatesd. condensation

The correct answer is option A, Wind Shear

Explanation:

The tornadoes are formed from the fast rotating air which develops into a funnel shape. This is the reason why tornadoes usually occur during the thunderstorm in a cumulonimbus cloud when the wind direction and speed changes at high altitude thereby producing horizontal air swirl.  Swirling air takes the shape of funnel and finally touches the base of the ground to become a tornado.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.
