What is the cause of weather effects occuring?

A. Energy from the sun causing chemical reactions in the atmosphere
B. Ocean currents moving air directly above the waves causes the weather effects over the water to be pushed onto land
C. Air of different characteristics meeting in a place called a front
D. The rotation of the earth causes masses of air to rotate with the earth, causing the creation of weather

All of the options mentioned play a role in causing weather effects to occur, but the most accurate answer would be:

C. Air of different characteristics meeting in a place called a front.

When air masses with different characteristics (such as temperature, humidity, and density) collide at a front, it can lead to the formation of various weather phenomena, including storms, rain, snow, and changes in temperature. This interaction between air masses is a key cause of weather effects.
