Would Australia And The Us Still Have Opposite Season If The Earths Orbit Around The Sun Were A Perfect Circle?
If the Earth’s orbit around the sun were a perfect circle then Australia and the US would still have opposite seasons at any given time of the year, true or false?

Absolutely. Cause the distance from the sun doesn’t influence the seasons, it’s the angle the Earth is to the sun. When it’s summer in North America, the angle to the sun is almost direct, making it warmer. When it’s winter in Australia, the sun is angled away from Australia, making it cooler.
That is true. The seasons are caused by the tilt of Earth’s rotational axis, relative to its orbital axis. The tilt is about 23 degrees.
If you think about it, the seasons can’t be caused by Earth’s proximity to the Sun, because the northern hemisphere experiences winter (the coldest season) when the southern hemisphere experiences summer (the warmest season).
True I think ——————The sun’s rays are pretty close to parallel to each other when they reach the Earth,
so, if the Earth’s axis of rotation were perpendicular to the plane of the ecliptic,
the direct rays of the sun would always shine on the equator (that is, the angle of incidence at the equator would be 90 degrees) and you would always see the sun just on the horizon at the North and South Poles (that is, the angle of incidence at the Poles would be zero).
If that were the case, we would have no seasons.http://daphne.palomar.edu/jthorngren/tut…
Yes, they would still exhibit seasons and in the same way: summer in USA means winter in Australia.
It’s because the seasons are caused by the *TILT* of the Earth, not the orbit.
The seasons are due to the axial tilt of the earth at present it is 23. 4 degrees. Not due to elliptical path of the Earth around Sun.
On January +++++++++++++4th We are nearest to Sun, but have winter in northern hemisphere>
Yes. The seasons are a result of the tilted axis of rotation.
The excentricity of the orbit of the earth is too small to make
much difference.
Yes. because it about inclination not orbit.
