Even if the earth was tilted, it would still rotate on its own axis. The axis would meet the earth at the poles and the regions surrounding those points would be polar regions. That would be true whatever the earth's tilt.
the earth would be weird.
There would be many changes. First there would be only one season all the time with minor differences when Earth is at perihelion and aphelion. The time of sunrise and sunset would not change and at the equator there would be 12h or night and day.
if there was no tilt we would not have any seasons because no part of earth would be tilted toward the sun.:))))))
Maryland would have no seasons if the Earth were not tilted because the hemispheres would always be in the same place in relation to the sun.
Pay close attention to your question. A maritime (meaning oceanic) air mass has moisture, therefore it's not dry. Polar (meaning from the polar region) air mass is cold, therefore it is cold. Hence a maritime polar air mass would be moist and cold...how hard was that?
There would be no four seasons if the earths axis was not tilted.
The would be polar regions so the question does not apply.

They would be more extreme: winters would be colder and summers would be hotter. The temperate zones would contract, and the polar and tropical zones would expand.
very very cold
Mainly, there would be no seasons.

without the tilted axis the whole planet would be impossible to live on since this angle is a state of equilibrium
If the axis was tilted 36 degrees, seasons would become much more intense. In reality, the earth's axis is tilted about 23 degrees. If we had a 36 degree axis tilt, summer in Ohio (or anywhere else outside of the polar regions) would be far too hot for human life. And winter outside of the equatorial regions would be far too cold.
it would probably be the same nights and days
You'd be in the north polar region.
It would receive more direct Sun in the summer.
