Explain the cause of the Earths' season.
I need a diagram for my explanation

Most textbooks have one, even in elementary school. What grade level and school system is this?
Sure! The cause of Earth's seasons is primarily due to the tilt of its axis. The Earth's axis is an imaginary line that passes through its North and South Poles. The axis is tilted about 23.5 degrees relative to its orbit around the Sun. This tilt is what gives rise to the changing seasons.
To better understand this concept, you can create a simple diagram. Start by drawing a circle to represent the Sun. Label it as "Sun" at the center. Then draw a smaller circle around the Sun to represent the Earth's orbit. Label it as "Earth's Orbit."
Next, draw another smaller circle within the Earth's orbit to represent the Earth itself. Label it as "Earth." Draw a small line coming out from the top of the Earth to represent its axis. Label it as "Axis."
Now, draw another line extending from the top of the Earth's axis at an angle of about 23.5 degrees. This line represents the tilt of the Earth's axis. Label it as "Tilted Axis."
To indicate the positions of the Earth during different seasons, draw four arrows around the Earth, each pointing away or toward the Sun. Label these arrows as "Summer," "Autumn/Fall," "Winter," and "Spring" in their respective locations.
Lastly, add labels to indicate the Northern Hemisphere (NH) and Southern Hemisphere (SH) on the diagram to help visualize how the seasons differ between the two hemispheres.
This diagram illustrates that as the Earth orbits the Sun, the tilt of its axis causes the Sun's rays to fall differently on different parts of the Earth throughout the year. When the Northern Hemisphere is tilted towards the Sun, it experiences summer while the Southern Hemisphere experiences winter. When the Northern Hemisphere is tilted away from the Sun, it experiences winter while the Southern Hemisphere experiences summer. The two intermediate seasons, spring and autumn/fall, occur when the Earth is not tilted towards or away from the Sun.
By referring to this diagram, you can provide a visual aid while explaining the cause of Earth's seasons.
