Question

why do hemispheres experience opposite seasons? * earths rotation direction variations in solar radiation different atmospheric pressures earths axial tilt

Explanation:

The Earth has a tilted axis of about 23.5 degrees. As the Earth orbits the Sun, this tilt causes one hemisphere to be more directly - exposed to the Sun's rays at different times of the year, while the other hemisphere is less so. This results in opposite seasons in the Northern and Southern Hemispheres. Earth's rotation direction affects day - night cycle, variations in solar radiation are a result of the tilt and orbit, and atmospheric pressures are related to weather systems but not the cause of opposite seasons.

Answer:

Earth's axial tilt
