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.

Carbohydrates, they are found in almost every food and are used by the body to create sugar in the blood.

Most of the energy we have is used from burning fats and carbohydrates, since the body likes to use proteins to rebuild itself.
