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.
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.
A high pressure system usually produces these conditions in winter. Continental polar (apex)
If the Earth's axis was not tilted, there would be no seasons as we currently experience them. The tilt is what causes different parts of the Earth to receive more or less direct sunlight at different times of the year, resulting in seasonal changes. Without the tilt, the amount of sunlight received by each region would be more consistent, leading to a more uniform climate across the globe.
Permafrost because the top layer is to weak to dig on or into. So the most reasonable answer would be permafrost
The air mass found at the North Pole is typically a polar maritime air mass. This air mass is characterized by its cool and humid nature due to its origin over the cold waters surrounding the Arctic region.
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.
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.
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.
In the southern polar region.
