Please answer this: I can use this background: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]  At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]  Now, I have a new situation: There were Two villages Berg village situated at 3000 ft, at the base of the mountain, and Steep village, situated at 8500 feet. People visiting the area always stop in Berg village and feel great, but they feel bad and winded once they get to Steep village.  Answer this question please: Which village has a higher atmospheric pressure?

Answer: Berg


Please answer this: I can use this background: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word “Open” in the sign below. Krypton gives off violet light and xenon gives off blue light.  Now, I have a new situation: A scientist named Kathy walks into her office to see two neon signs plugged into the wall and hanging above her desk. Confused, she looks around to see if there's any clue as to who put them there. Seeing nobody, she flips the light switch on and walks in. Upon flipping the light switch, only the large sign lights up. Even though they are clearly both plugged in, the small sign isn't turning on. Kathy leaves her office to find someone to ask who put these random signs up in her room.  Answer this question please: Which sign's electrons are at a higher energy level?
++++++++
Answer: large sign


Please answer this: I can use this background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy.  Now, I have a new situation: An alien passing by Earth in a UFO to write a report on two random cities so that his government can better understand what the people of Earth are like. He first flies over Nillmar, a city in France, which uses burns coal as its main production of electricity. After observing Nillmar, the alien flies over to Springfield, a city in the United States, that decided to use nuclear power to fuel itself. After taking his notes, the alien leaves and is eager to report back to his superiors about what he discovered.  Answer this question please: What city is contributing less to global warming?

Answer:
Springfield
