II. Exposition Explaining the Most Fascinating Natural Phenomenon by Exceptional Students
1. Exposition Explaining the Appearance of Super Enchanting Rainbows - Sample 1:
Mother Nature has bestowed upon us an exquisite ecosystem, along with captivating and intriguing natural phenomena. One of the most common and visible wonders is the rainbow.
A rainbow consists of contiguous bands of colors: red, orange, yellow, green, blue, indigo, and violet, appearing in the sky right after a rain shower. This phenomenon is quite fascinating from a physics standpoint. The sunlight, composed of a mix of colors invisible to the human eye, creates the spectrum when passing through a glass prism. The refracted light forms a continuous band of colors known as the spectrum.
In the realm of nature, water droplets can play the role of a lens. After a refreshing rainfall, suspended water particles linger in the air. When the Sun's rays encounter them, they gracefully bend and reflect, departing at an angle of 42 degrees. The colors within sunlight disperse in a specific order: red bends the least, while violet bends the most. This enchanting phenomenon is the rainbow we often marvel at.
This optical spectacle emerges from sunlight and water vapor, revealing itself only after a rain shower. To catch a glimpse of the rainbow, one must stand at a distance with their back to the Sun.
Beyond the ordinary rainbow, one might encounter a double rainbow. This occurrence arises from the diffraction of light. Alongside the primary rainbow, a secondary rainbow with inverted color bands appears faintly above.
Rainbows can also grace the night, courtesy of Moonlight. This phenomenon is aptly named Moonbow.
Sample Essay: Explaining a Natural Phenomenon for Gifted Students
2. Explanatory Essay on the Phenomenon of Aurora - Example 2:
Auroras, a fascinating natural phenomenon, are rare but unfortunately absent in Vietnam. What makes this event so special? In this article, we will explore the wonders of auroras.
Earth acts as a colossal magnet with magnetic poles, namely the North and South Poles. The atmosphere, bombarded by high-energy rays from space, releases numerous free electrons. Guided by Earth's magnetic field, these electrons move towards the North and South Poles. As they interact with other elements in the air, they produce a spectrum of lights in various colors such as green, purple, and yellow. This enchanting display is what we know as the aurora borealis and australis.
Gazing at the auroras, one witnesses an array of vibrant, cascading beams resembling flowing ribbons across the night sky. It's a breathtaking, surreal image, truly a gift bestowed upon humanity by Mother Nature.
Due to the influence of Earth's magnetic field, this phenomenon occurs exclusively at the North and South Poles, in countries like Finland, Sweden, Canada, Norway, etc. The prime time to witness the auroras is between September and April. Western countries, with short nights and long days, offer optimal viewing conditions from 9 p.m. to 3 a.m. when the night sky is dark enough to reveal these luminous streaks.
Beyond Earth, other planets like Mars, Venus, Jupiter, Saturn, and Neptune also boast auroras. These planets, possessing magnetic fields, interact with particles in the solar wind, creating fascinating celestial displays.
Auroras are a marvel of nature that one should experience at least once in a lifetime. Travel to these countries to witness this spectacle firsthand, or in the absence of such opportunities, explore online videos to delve deeper into the enchanting world of auroras.
