the two things that cause seasons on Earth are the orbit around the sun and the tilt on its axis.

One is the tilt of the earth's axis at 23.4 degrees to the vertical. The other is the annual orbit around the sun, which exposes each hemisphere in turn to more than 12 hours of sunlight.
SEASONS
In temperate and polar regions generally four seasons are recognized: spring, summer, autumn (fall), and winter.
In some tropical and subtropical regions it is more common to speak of the rainy (or wet, or monsoon) season versus the dry season, as the amount of precipitation may vary more dramatically than the average temperature.
In other tropical areas a three-way division into hot, rainy and cool season is used. In some parts of the world, special "seasons" are loosely defined based upon important events such as a hurricane season, tornado season or a wildfire season.
The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.44 degrees. Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun.
This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons.
Seasonal weather fluctuations also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Niño/ENSO and other oceanic cycles, and prevailing winds.
In the temperate and polar regions, seasons are marked by changes in the amount of sunlight, which in turn often causes cycles of dormancy in plants and hibernation in animals.

Tilt of the Earth-23.5 degrees-and revolution of the Earth around the sun.

One is the tilt of the earth's axis, the other is that it orbits the sun.

The tilt in our axis, the inclination of our ecliptic plane
and
The atmosphere... without it, there would be no weather.

the point at which the earth is during its revolution around the sun
Exe: earth is farther away from sun in it revolution = winter
earth is closer to the sun during its revolution = summer
