Answer:
Hello. You did not enter the answer options, but what causes the variation in seasonal weather patterns is the tilt of the earth's axis.
Step-by-step explanation:
The variation in seasonal weather patterns is caused by the tilt of the earth's axis. This axis is composed of an imaginary line that crosses the earth from one pole to another. This causes an inclination. The earth rotates around this axis and this slope causes the hemispheres to receive sunlight unevenly for a year, causing one pole to receive more sunlight at a time of the year, while the other pole receives more sunlight. at another time of the year. This is exactly what causes variation in seasonal weather patterns.
This is because, the pole that is receiving the highest incidence of solar rays, is with the sun positioned in maximum form in relation to its axis of inclination of the earth.
