Yes the sun enters the northern hemisphere.
Exactly at the poles, the cycle is very simple and regular. At the north pole, the sun rises on March 21 and sets on September 21. At the south pole, the sun rises on September 21 and sets on March 21. And that's the whole story.

There is no place on the surface of the earth where the sun never sets. As seen from the North Pole, the sun is above the horizon continuously from March 21 until September 21. As seen from the South Pole, the sun is above the horizon continuously from September 21 until March 21.
March 21 and September 21.
From September 21 until March 21.
The sun's path is highest in the sky at noon on June 21 at this location, indicating the summer solstice when the sun reaches its highest point in the sky.
The apparent path of the sun is observed daily as it moves across the sky from east to west. However, specific observations can vary based on the time of year and location. For example, the summer solstice, around June 21, marks the longest day of the year in the northern hemisphere, showcasing the sun's highest path. In contrast, the winter solstice, around December 21, features the sun's lowest path.
The South Pole begins its rotation away from the sun on March 21, and on June 21, it changes course and begins its rotation toward the sun.
The equinoxes (approximately 21 March & 21 Sept).
No. The sun is directly over the equator once near March 21 and again near September 21.
March 20 or March 21, depending on where you live The time when the sun crossed directly over the equator was 03:52 UTC on March 21.
Does the tilt of the earths axis CAUSE the change of temperature? Not directly, but there are several factors that link together, so that the Earth's axial tilt is related to the change in temperature as a "trailing indicator".The Earth rotates constantly on its axis like a gyroscope does. Compared to the plane of the Earth's orbit around the Sun, the Earth's axis is tilted at an angle of about 23.5 degrees. As the Earth proceeds around its orbital path, the sunlight we receive is more directly vertical to the ground when the pole is tilted toward the Sun; that is to say, during the spring and summer. That's March 21 through September 21 in the northern hemisphere, and September 21 through March 21 in the southern hemisphere.Because the Sun beats down more directly, this causes the Earth to begin heating up a little more. But notice that the real hot weather doesn't occur for about 3 months after the Spring Equinox, and a month or so after the Summer Solstice - when the Sun is already heading into fall.
