Question

A thunderstorm is generally accompanied by:
(A) lightning
(B) earthquake
(C) fire
(D) mild breeze

Answer 1

Hint: Thunderstorms are formed when the warm and moist air rises into the clouds and into cold air. To create the thunderstorm, the unstable air needs to have a nudge upward. This air lift usually comes with the difference in air density.

Complete step by step answer:
When the warm and moist air from the ground rises into the cold air. This process of falling and rising of air is called a convection cell. If this happens with very small amounts the normal cloud will form. If this happens with a very large amount of air and moisture, then the thunderstorm will happen. All thunderstorms need some moisture, unstable air and lift of air. Moisture usually comes from the oceans. Unstable air is formed, when the warm, moist air is near the ground and cold, dry air is above the ground. Lift will come from the differences in air density. So, it pushes the air upward, creating the big thunderstorm clouds.
The rising air in the thunderstorm cloud which contains very small ice crystals and pellets. The Collisions happen between the ice gems and the pellets, and these crashes fill in the charging component of the thunderstorm. The little ice precious stones become decidedly charged while the pellets become negatively charged. So, this charge difference may lead to lightning.
Thus, the thunderstorm is generally accompanied by lightning.
Hence, the option (A) is the correct answer.

Note: When the charge difference between the ground and the cloud becomes too large, a conductive channel of air develops between the cloud and the ground, and a small amount of charge starts moving toward the ground. At that instant the connection is made to discharge a powerful charge occurs between the cloud and the ground. So, the flash of light will occur.
