solstice
alpha rays follow north pole of magnet and beta rays south pole.
Between 23.5° south latitude and 23.5° north latitude.
It takes approximately 8 minutes and 20 seconds for the sun's rays to reach the Earth perpendicularly.
Ozone layer is situated in the stratosphere. It does not allow UV rays to enter.
The tropic of Cancer is 23° North of the Equator. It represents the point where the Sun can be directly overhead. If you are any further north, the Sun can not be overhead. The corresponding feature in the southern hemisphere is the Tropic of Capricorn. As to the Sun's direct rays, they can be anywhere from the South Pole to the North Pole. Those two points and everything in between receives the Sun's direct rays at some time during the year.
solstice
The farthest south that the vertical rays of the sun reach south of the equator occurs around December 21st each year, which is the summer solstice in the Southern Hemisphere. This marks the beginning of summer in the Southern Hemisphere.
North and south pole
the suns rays
No, it is the angle in which the sun's rays hit our planet. AT the moment it is roughly 23.5 degrees. This is why the South poles has a larger ozone "hole" then does the North pole.
The north and south poles
The further south or north from the equator, the shallower the angle of the sun's rays hitting the earth's surface. This means that the rays travel through the atmosphere further and so have time to cool. The sun's rays hit the equator dead on, concentrated, but they hit the North and South pole at an angle, so the heat is spread out over a larger area.
The axis of the planet Earth is declined in the sense of its rotation around the Sun. That's why the Sun rays reach more the North hemisphere when the South hemisphere faces away from it.
the red circle is a sun and the 16 rays represent the 16 points of a compass -- North, North North East, North East, East North East, East, East South East, South East, South South East, South, South ...

North and south pole
alpha rays follow north pole of magnet and beta rays south pole.
At the time of the equinoxes, the sun's rays would be nominally tangent to the Earth at the north and south poles. Those are 90 degrees north and south of the equator respectively. Also I think at either 23.5 degrees north or 23.5 degrees south at sunrise and sunset.
