Write an informative essay that explains a natural phenomenon such as the Pitch Lake in Trinidad or the aurora borealis.

Answer:Every storm cloud has a silver lining; in the case of space weather, that lining is the aurora borealis, more commonly known as the Northern Lights. (Viewers in the southern hemisphere are treated to an equivalent version called the aurora australis, or Southern Lights.) The phenomenon is best observed on a clear, cold night around the spring or autumn equinox. Find an open patch of sky well away from the interfering lights of the city, and you may catch a glimpse of the spectacle: curtains of pale light-green and blue, sometimes red or violet-shimmering above the northern horizon for minutes or even hours at a time.

Auroras occur when electrons and protons from the Sun strike gas molecules in Earth's upper atmosphere. As the solar particles encounter Earth's magnetosphere, they are drawn along the magnetic field lines and funneled toward the North and South poles. There, high above Earth's surface, they collide with atmospheric molecules, energizing them and causing them to glow. The colors that result depend on the gas molecules involved. The brightest and most common auroral color, a brilliant yellow-green, is produced by the glow of oxygen molecules roughly 60 miles above Earth. Ionized nitrogen molecules emit blue light when hit by solar particles; neutral nitrogen molecules emit a purplish-red light. All-red auroras are rare; they are caused by the glow of oxygen atoms 200 miles above Earth. The size and intensity of the aurora varies from night to night, and moment to moment, depending on the strength of the solar wind. On April 6, 2001, a large geomagnetic storm produced an aurora that was seen as far south as Alabama. The scientific understanding of auroras has advanced enormously in recent years with the launch of satellites designed expressly to study them. Instruments aboard NASA's Polar spacecraft monitor ultraviolet radiation and chemical changes in the upper atmosphere, effectively offering an up-to-the-minute report on the shape and intensity of the aurora. The Imager for Magnetopause-to-Aurora Exploration (IMAGE) spacecraft, launched in 2000, studies Earth's magnetosphere in astounding detail. It can watch auroras evolve over a period of hours, and can even see auroras flickering in the far-ultraviolet wavelength. Recently and for the first time, scientists observed a phenomenon known as "black auroras." A black aurora isn't really an aurora at all: it's the dark, empty space within a colorful aurora where one would otherwise expect auroral activity to be visible. Nonetheless, black auroras exhibit distinct patterns, including curls, rings and writhing black patches. Nowadays, scientists often can forecast a spectacular aurora hours or days in advance, so it's worth checking space weather websites (See Related Links) with some regularity.

In the 1970s, with the aid of the Hubble Space Telescope, it became apparent that Earth is not the only planet with auroras. On both Jupiter and Saturn, auroras appear pink due to the large amounts of hydrogen in those planets' atmospheres. Jupiter's aurora has proved to be particularly intriguing. On Earth, the aurora is powered by a barrage of charged particles from the Sun. On Jupiter, auroras are generated instead by volcanic particles from the Jovian moon Io. These particles become ionized, expand and then are trapped in Jupiter's tremendous magnetic field. Rotating once every ten hours, Jupiter generates auroras many times more powerful than those on Earth. However, Earth's auroras remain unique in one respect: they are (at times, anyway) green. Indeed, Earth is the only known planet with green auroras, because it is the only known planet with an oxygen-rich atmosphere. As scientists look deeper into the universe for signs of other, potentially habitable worlds, auroras are one clue they examine. If a distant, unknown planet has shimmering green auroras, that's a strong indication that its atmosphere is rich in oxygen, perhaps enough to support life. Whether that life is capable of appreciating the auroras—well, that's another issue.

Skateboarding became popular in the 1950s. It was originally called sidewalk surfing. This is because it is an
offshoot of surfing. Surfing is the ancient sport of riding a wooden board through ocean waves. Surfing is still
popular today. Like surfing, skateboarding has become its own sport. The most skilled skaters are paid by shoe,
clothing, and even soda companies. They are given money to wear certain products.

Doubting Rhea
by Samantha Dias

Rachel and Rhea had been best friends since kindergarten and thought they would be best friends forever. But once they began middle school, Rachel began to feel that Rhea was growing distant from her. They didn’t spend as much time together as they did in elementary school. They were in different clubs and had different classes. Over the past few weeks, Rhea had been avoiding Rachel, or so Rachel thought. This coming weekend would mark a month since they had last spoken. Rachel worried that Rhea had tired of her. The thought made Rachel want to run up to Rhea and demand an explanation, but instead she burst into silent sobs.

Saturday was Rachel’s birthday. She had planned a little party just for her and Rhea. But when the time came, Rhea didn’t show up. Rachel was sure her friend couldn’t have forgotten her birthday, and she waited all evening for her call. Rachel was about to give up, when she heard the doorbell. There stood Rhea at the front door shouting, “Hey, Birthday girl!!”

Rachel frowned, “So you finally remembered.”

“What do you mean?” Rhea asked. “Of course I remembered. It’s the reason I haven’t been able to meet you these past weeks.”

Rachel replied warily, “You really think I’m going believe that?”

Rhea smiled. “When you see your gift, you’ll have no choice but to believe me.”

Rhea led Rachel to a nearby playground, where a stage had been set up. Rhea beamed at Rachel as the members of Incandescent Chihuahua, Rachel’s favorite band, walked onto the stage.

Rachel hugged her friend. “I don’t believe my eyes! How did you do this?”

Rhea smiled, “I wanted your 15th birthday to be special. You missed their concert last year. Their agent owed my dad a favor, but my dad said I had to earn it. So I’ve been working as his assistant for the last month, which is the reason I’ve been so busy. I couldn’t say anything because it’s so hard for me to keep a secret from you.”

Rachel couldn’t believe how petty she had been and promised herself that she would never jump to conclusions again.
