Why is it hot at night near the equator when the sun goes much further below the horizon than in the polar regions in the winter?
DiamondXmas
It really doesn't matter how far below the horizon the Sun is, when looking at temperature differences. Once the Sun is more than a degree below the horizon, there is no longer any solar heating of the surface of the Earth.
But solar heating is only one of several factors in the temperature. When the Sun is up, the incident angle of sunlight is far more important, and in the tropics the Sun is often very high in the sky. (At lower angles, the Sun's radiation is spread out over a larger area of the Earth.) And because the atmosphere holds in heat and prevents it from immediately radiating away, the heat of the earth or oceans preserves the temperature quite well.

How would the general circulation of air appear in summer and winter if the earth were tilted on its axis at an angle of 45 degrees instead of 23.5 degrees?
The ITCZ would shift further north in the northern summer and further south in the northern winter. Similarly the subtropical highs and polar fronts would shift further from the equator during the summer and closer to the equator in the winter in both hemispheres than is now the case.
Why do some states get snow every winter?
It depends on their location and other natural factors. The further somewhere is from the equator, the colder its winter will be. So places further from the equator are more likely to get snow. Places with high mountains in those areas far from the equator are more likely to get snow than at ground level. Winds and even sea currents can have an impact. So there are lots of reasons why some places get snow.
When it is winter above the equator what season is it below the equator?
If it is summer at the South Pole, then everywhere in the northern hemisphere is experiencing winter.
What is it called when the sun is at its greatest distance from the equator?
It is called "an equinox" because on that day the Sun (nominally) spends as much time above the horizon as below the horixon all over the World. This is a truth with modifications but close enough for general consideration.
Is winter solstice a bad thing?
no it is not, it is when the sun is southern from the horizon of the earth
Does the seasonal cycle occurs because Earth is closer to the sun in the summer than in the winter?
The Earth rotates on it's axis. In the summer, the Earth is tilted towards the sun. In the winter, the Earth is titled away from the sun. On the Earth, the northern regions (above the equator) have winter, while the southern regions (below the equator) have summer. Then, the opposite becomes true. The southern regions have winter, while the norther regions have summer. The distance nearer and farther from the sun makes no difference as far as the Earth's summer and winter is concerned.

Is it true the point of sunrise on the horizon is always the same?
No. The point of sunrise changes with the seasons. In winter sunrise will be further to the north (southern hemisphere) than in the summer

What can birds do instead of going hibernate?
They can migrate to different regions. The birds in the Northern hemisphere go south during winter. The birds in the Southern hemisphere go north during winter. They migrate towards the equator.
What is solar altitude?
How high the sun is in the sky. The angle between the horizon and the sun. When the sun is directly overhead (eg, at the equator) the solar altitude is 90°. In Canberra in winter, the solar altitude is 30°.
When it is winter above the equator what season is it below the equator?
If it is summer at the South Pole, then everywhere in the northern hemisphere is experiencing winter.
How long is the day in winter and summer?
That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).
When is winter in Africa?
It depends where you are in Africa. If you are North of the Equator winter is December, January, and February. If you are South of the Equator your winter is June, July, and August.
When is winter in Guatemala?
Winter in the northern hemisphere is always in December, January, February and in the southern hemisphere it is June, and July and August. Countries so near to the equator will not experience such extremes of weather as those further away. Guatemala is in the northern hemisphere so winter is as stated above. However in terms of weather the hottest time on the equator is when the sun is overhead at the spring and autumn equinox.

It is called "an equinox" because on that day the Sun (nominally) spends as much time above the horizon as below the horixon all over the World. This is a truth with modifications but close enough for general consideration.
How does temperature change from winter to spring?
In the Northern Hemisphere there will be a general warming trend and in the Southern Hemisphere there will be a general cooling trend. These effect are more noticeable the further from the equator you go
