Well the use of trenches prolonged WWI because it was another kind of land warfare where most of the ground in which they were fighting consisted mostly trenches. These trenches protected them from most artillery and normal gun fire. So it was almost like a stalemate.
Answer: Urban = Hight Population Density
Suburban = medium density
rural = low density
Explanation: Think of the areas which are described. In a city, people are usually packed in tight areas, such as apartment buildings. Cities usually have the highest population as well. In suburban areas(neighborhoods) there are still a big population but, they are more spaced out. In rural areas(farms, small towns) there are less people. Because of this, they are more spread out.
On December 7, 1941, the United States naval base at Pearl Harbor, Hawaii was attacked by the Japanese navy, bringing about the US entry into the Second World War. Often referred to as “waking a sleeping giant,” the attack on Pearl Harbor began a course of events that ultimately led to the defeat of the Axis Powers. The attack on Pearl Harbor killed 2,403 Americans and wounded 1,178 others. Nearly sixty years later, 2,977 people died in the attacks of September 11, 2001, when Bombers linked to al-Qaeda hijacked four planes, flying two into the World Trade Center in New York and one into the Pentagon (a fourth crashed in Pennsylvania). These attacks led to a worldwide war against terrorism led by the United States. Both attacks caused widespread public response and xenophobia. This source set includes artifacts from both events in order to compare them.
Break dancing, also called breaking and B-boying, energetic form of dance, fashioned and popularized by African Americans and U.S. Latinos, that includes stylized footwork and athletic moves such as back spins or head spins. Break dancing originated in New York City during the late 1960s and early ’70s, incorporating moves from a variety of sources, including martial arts and gymnastics.
Break dancing is largely improvisational, without “standard” moves or steps. The emphasis is on energy, movement, creativity, humour, and an element of danger. It is meant to convey the rough world of the city streets from which it is said to have sprung. It is also associated with a particular style of dress that includes baggy pants or sweat suits, baseball caps worn sideways or backward, and sneakers (required because of the dangerous nature of many of the moves).
The term break refers to the particular rhythms and sounds produced by deejays by mixing sounds from records to produce a continuous dancing beat. The technique was pioneered by DJ Kool Herc (Clive Campbell), a Jamaican deejay in New York who mixed the percussion breaks from two identical records. By playing the breaks repeatedly and switching from one record to the other, Kool Herc created what he called “cutting breaks.” During his live performances at New York dance clubs, Kool Herc would shout, “B-boys go down!”—the signal for dancers to perform the gymnastic moves that are the hallmark of break dancing.
In the 1980s breaking reached a greater audience when it was adopted by mainstream artists such as Michael Jackson. Jackson’s moonwalk—a step that involved sliding backward and lifting the soles of the feet so that he appeared to be gliding or floating—became a sensation among teens. Record producers, seeing the growing popularity of the genre, signed artists who could imitate the street style of the breakers while presenting a more-wholesome image that would appeal to mainstream audiences. Breaking had gone from a street phenomenon to one that was embraced by the wider culture. It is around this time that the term break dancing was invented by the media, which often conflated the repertoire of New York breakers with such concurrent West Coast moves as “popping” and “locking.” Those routines were popularized in the early 1970s by artists on television, including Charlie Robot, who appeared on the popular TV series Soul Train.
