U realise that the point number is 15 not 30?
But here is an 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.

Explanation:
Greek Thinkers, Artists, Writers, and Leaders Discussion In this discussion, you will rank the three individuals from the lesson who you feel most contributed to modern Western society. You will cite two pieces of evidence from the lesson per individual to explain and support your rankings.
The correct answer to this open question is the following.
You did not include information about the three individuals from your lesson. So we do not know what you learn in your specific lesson to provide evidence from that lesson.
However, we can comment on the following general terms. The three thinkers, philosophers, or artists that influenced the western world were Cleisthenes, Socrates, and Homer.
Cleisthenes was an important ancient Greek leader that received the influence of Solon and developed the concept of democracy. A new system of government in which the Greek citizens had the right to choose their rulers. Democracy became one of the most influential political systems in the modern world.
Socrates(470BCE-399BCE) was an ancient Greek philosopher, probably the greatest philosopher of ancient Greece, whose Socratic method impacted the modern world. He was an extraordinary teacher that taught in the Agora in Athens and believed in establishing a system of ethics in which the human reason would be the foundation of his teachings.
Homer(800BCE-701BCE) was a great poet and writer in ancient Greece, who is the author of the two epic poems the "Iliad" and the "Odyssey." Both texts describe the mythology and life in ancient Greece and are considered the two most influential books of the Greek culture.
Why are currency exchange systems important for international trade?
Group of answer choices
They make it more difficult for countries to impose tariffs on foreign goods.
They make it more difficult for smugglers to sell foreign goods.
They make it easier for countries with different kinds of money to trade with each other.
They make it easier for people who speak different languages to trade with each other.
Answer:
The reason why we need a system of currency exchange in order to conduct international trade is because different countries use different types of currency. They do so because national sovereignty allows each nation to establish its own currency. However, we need a system to pay for goods that are purchased from other countries. This is why the currency exchange system allows us to conduct international trade

Why might Lincoln refer the audience to think about that particular year when they are burying soldiers who fought in the Civil War?
During LincoIn and the Civil war, the audience and remind them of the founding of our nation, Lincoln makes a reference to this year. The civil war during the period was fierce, and there were innumerable deaths.
What are the effects of the Civil War?He wished for the end of the Civil War, and when he speaks of "a new nation, formed in Liberty, and dedicated to the notion that all men are created equal," he is expressing his belief that the war, the dead, and the necessity to rebuild the united country that we once were are all wrong.The fact that he described the slaves as "one-eighth of the whole population" demonstrated that he no longer thought of them as a foreign, insurmountable element but rather as an integral component of the country. Of fact, Southerners themselves had frequently referred to slavery as "peculiar." Republicans' prewar claims about Slave Power were recalled by the word "powerful." By blaming slavery for the violence, the South was made accountable for it. Lincoln omitted to assign responsibility, though, adding just "and the war began." Lincoln continued that the war had produced unexpected results: Neither party anticipated the war, its magnitude, or its already long endurance.To learn more about Civil War refer to:

what is one thing Theodore Roosevelt could have done better?
Answer: here el oh el
Explanation:
One negative thing that could be leveled against Teddy Roosevelt was that he instigated the American intervention in the Philippines during the Spanish-American War. After the American battleship The Maine exploded in Havana harbor in 1898, causing the deaths of 258 crew members, Roosevelt told Admiral Dewey that if war broke out between the United States and Spain, he was to head to Manila to launch an attack. At that time, Roosevelt was Assistant Secretary of the Navy, and he acted when his boss, the Secretary of the Navy, was away from the office. As a result, Dewey headed to Manila Harbor and launched an attack against Spanish troops there and took control of the Philippines. This ushered in a period of overseas American imperialism and aggression against foreign powers.
What do all nations that had on Industrial Revolution have in common?
Explanation:
The Industrial Revolution marked a period of development in the latter half of the 18th century that transformed largely rural, agrarian societies in Europe and America into industrialized, urban ones.
Goods that had once been painstakingly crafted by hand started to be produced in mass quantities by machines in factories, thanks to the introduction of new machines and techniques in textiles, iron making and other industries.
Fueled by the game-changing use of steam power, the Industrial Revolution began in Britain and spread to the rest of the world, including the United States, by the 1830s and ‘40s. Modern historians often refer to this period as the First Industrial Revolution, to set it apart from a second period of industrialization that took place from the late 19th to early 20th centuries and saw rapid advances in the steel, electric and automobile industries.
