What contributes to the movement of air masses? a. weather boundaries b. natural wind patterns c. air pressure differences d. rapid changes in weather

B). natural wind patterns, I took the Cumulative Exam.

The correct answer is option B, natural wind patterns

Explanation:

An air mass moves along with the air flow in the upper atmosphere. Whenever a jet stream changes its potion and its intensity of flow, it leads to the movement of air mass. An air mass movement is not affected by the characteristic of its source regions, however the physical characteristic of an air mass(i.e temperature, pressure of air mass etc.) are entirely determined by the physical characteristics of its source region

the core of the sun is so hot and there is so much pressure, nuclear fusion takes place, hydrogen is changed to helium. nuclear fusion creates heat and photons. when the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.

the answer is trees if i'm not mistaken
