sesons
To understand the reasons for the seasons, you need to consider the Earth's tilt and its movement around the Sun. Here's how you can explain it in your portfolio:
1. Explain the Earth's tilt: The Earth is not perfectly upright, but rather tilted on its axis at an angle of about 23.5 degrees. This tilt remains constant throughout the year.
2. Discuss the Sun's rays: The Sun emits light and heat in the form of solar radiation. The angle at which this radiation reaches the Earth's surface determines the intensity of sunlight received at any specific location.
3. Explain the concept of direct and indirect sunlight: When the Earth's tilt causes one hemisphere to be tilted towards the Sun, it receives more direct sunlight, leading to warmer temperatures and longer days. This is known as summer in that hemisphere.
4. Contrast with the opposite hemisphere: At the same time, the other hemisphere is tilted away from the Sun, receiving less direct sunlight and experiencing cooler temperatures and shorter days. This is known as winter in that hemisphere.
5. Discuss the equinoxes: In between the summer and winter solstices, there are two equinoxes - the vernal (spring) equinox and the autumnal equinox. During these times, neither hemisphere is tilted towards or away from the Sun. This results in almost equal day and night lengths, known as the equinox.
6. Mention the impact on seasons: As the Earth continues to orbit the Sun, the angle at which sunlight reaches a specific location changes. This causes the seasons to cycle throughout the year, with each hemisphere experiencing summer, autumn, winter, and spring.
7. Address the influence of the axis tilt and revolution speed: The Earth's tilt and its revolution speed around the Sun determine the duration of each season. For example, the hemisphere tilted towards the Sun receives sunlight for a longer duration, while the opposite hemisphere experiences shorter days.
By presenting these explanations in your portfolio, you can demonstrate your understanding of the reasons for the seasons and how they are related to the Earth's tilt and its movement around the Sun.
