Seasons
what the planet's revolution and rotational movement are;
that the Earth's axis is inclined in its orbit around the Sun.;
the length of day and night varies throughout the year.
discuss differences in the earth’s climate at the beginning of particular seasons;
explain the relationship between the tilt of the earth's axis and the variability of the seasons.
Poles, when asked about the number seasonsseasons, will say four: spring, summer, autumn, winter. In other places in the world, only two seasons exist. There are also areas where the same weather prevails throughout the year, so the seasons do not stand out! What is the reason for this?
The annual movement of the Earth around the Sun is also on a constant tilt on its own axis which causes the lighting of various parts of the Earth to change in a repetitive manner. Changes in lighting, in turn, cause seasonal changes. The spring equinox in the northern hemisphere means the beginning of spring in Poland. At the same time autumn begins in the southern hemisphere. With autumn equinox, autumn begins, and in the southern hemisphere – spring. Similarly, at the summer solstice, summer begins for us, while in the southern hemisphere it is the beginning of winter.
Explain why most of the insect eating birds and those living around water fly from Poland in autumn.
Indicate the moment when the days in the northern hemisphere are the longest.

- summer solstice – 22 XII
- autumn solstice – 22 IX
- summer solstice – 22 VI
- the spring solstice – 21 III

Summary
Earth's orbit around the Sun takes 365 days 5 hours and 49 minutes.
The tilt in the axis of it's rotation in combination with the orbit creates the seasons on Earth.
The southern hemisphere has the same seasons as the northern hemisphere, but the dates of their beginning and end are different.
