i need help with a reason for the season science lab of how earth orbits sun
earth's axis tilts. The hemisphere pointing toward the sun receives more light and heat, and experiences summer, while the opposite hemisphere has winter.
google is your friend. just look for stiff on "seasons axis tilt" and you will find lots of discussions.
Does anyone have the answers to 2.15 earth's seasons pool 2 k12 forces and earth quiz?
yes i dooo
Certainly! Understanding the reason for the seasons is a fundamental concept in Earth science. The relationship between the Earth and the Sun and how the Earth orbits the Sun plays a crucial role in the changing seasons. Here's an explanation of Earth's orbit around the Sun and how it connects to the seasons:
1. Earth's Revolution: The first thing to understand is that the Earth follows a path around the Sun called an orbit. This orbit is not a perfect circle but rather an elliptical shape. It takes approximately 365.25 days for the Earth to complete one full orbit around the Sun. This duration is what we consider a year.
2. Tilted Axis: The second factor to consider is the Earth's axial tilt. The Earth is tilted on its axis by about 23.5 degrees. This tilt remains constant throughout the year, and it is this tilt that causes the changing seasons.
3. Seasonal Changes: As the Earth orbits the Sun, different parts of the Earth receive varying amounts of sunlight throughout the year. This occurrence results in the changing seasons. Let's break it down:
a. Summer: When a particular hemisphere (either the Northern or Southern Hemisphere) is tilted towards the Sun, it receives more direct sunlight. This results in longer daylight hours, shorter nights, and warmer temperatures. It corresponds to summer for that hemisphere.
b. Winter: Conversely, when a hemisphere is tilted away from the Sun, it receives sunlight at a lower angle, spreading the same amount of energy over a larger area. This causes less direct sunlight, shorter daylight hours, longer nights, and cooler temperatures. It corresponds to winter for that hemisphere.
c. Spring and Autumn: During spring and autumn, neither hemisphere is tilted directly toward or away from the Sun. As a result, the sunlight is spread more evenly, resulting in milder temperatures during these seasons.
To summarize, the Earth's orbit around the Sun, combined with its axial tilt, determines the amount and angle of sunlight reaching different parts of the globe, leading to the change in seasons.
