input question: Two students learned about soils in school. Brad had to study forest soils, while his colleague Frank had to study grasslands. They both did a good job and received A's for their efforts and accumulated knowledge. Which student read more about slow rates of decomposition? Hint: Soil is well developed in the forest as suggested by the thick humus layers, rich diversity of large trees and animals that live there. In forests, precipitation exceeds evapotranspiration which results in an excess of water that percolates downward through the soil layers. Slow rates of decomposition leads to large amounts of fulvic acid, greatly enhancing chemical weathering. The downward percolation, in conjunction with chemical weathering leaches magnesium (Mg), iron (Fe), and aluminum (Al) from the soil and transports them downward, a process known as podzolization. This process leads to marked contrasts in the appearance and chemistry of the soil layers.???

John was interested in the Sun's radiations that Earth receives. One of the radiations was in the ultraviolet spectrum. He categorized it as spec A. The other radiation was the visible light. He categorized it as spec B. He then searched online to find the pros and cons of each of them. Which radiation would be more hazardous, spec A or spec B? Hint: There is a zone of the atmosphere in which ozone absorbs some 98% of non-ionizing but dangerous UV-C and UV-B. This so-called ozone layer starts at about 20 miles (32 km) and extends upward. Some of the ultraviolet spectrum that does reach the ground (the part that begins above energies of 3.1 eV, a wavelength less than 400 nm) is non-ionizing, but is still biologically hazardous due to the ability of single photons of this energy to cause electronic excitation in biological molecules, and thus damage them by means of unwanted reactions. An example is the formation of pyrimidine dimers in DNA, which begins at wavelengths below 365 nm (3.4 eV), which is well below ionization energy. This property gives the ultraviolet spectrum some of the dangers of ionizing radiation in biological systems without actual ionization occurring. In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.

Q: Wade county was situated to the east of Gray county. Due to a favorable landscape, Wade county built more roads and railways. Which county will have fewer advances in communications technology? Hint: Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease. With the advent of faster travel, distance has less effect than it did in the past, except where places previously connected by now-abandoned railways, for example, have fallen off the beaten path. Advances in communications technology, such as telegraphs, telephones, broadcasting, and internet, have further decreased the effects of distance.[1]

Question: Tony is heating up a container of leftovers in his microwave for dinner tonight. When he puts the container in the microwave he leaves the lid on so it is still sealed. About two minutes into heating the food he hears a loud "pop" noise and looks to see the lid has completes blown off the container. Will increasing the temperature in a sealed container increase or decrease the pressure inside the container? Hint: The Figure below shows a graph of plotted against pressure for 1 mol of a gas at three different temperatures - 200 K, 500 K, and 1000 K. An ideal gas would have a value of 1 for that ratio at all temperatures and pressures and the graph would simply be a horizontal line. As can be seen, deviations from an ideal gas occur. As the pressure begins to rise, the attractive forces cause the volume of the gas to be less than expected and the value of drops under 1. Continued pressure increase results in the volume of the particles to become significant and the value of rises to greater than 1. Notice, that the magnitude of the deviations from ideality is greatest for the gas at 200 K and least for the gas at 1000 K.
Answer: increase

[Q]: Two researchers looked at the human influence on atmospheric carbon dioxide levels. Tim studied a human settlement from 10000 years ago, while Bob studied a present day county. Today's economy in the county revolved around extensive agriculture. Which researcher found that clearing often involves burning? Hint: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs.

Problem: Given the question: John and Jacob are both store owners hoping to attract more attention to their stores by using neon signs. Since both of them will be in their store for so many hours, they want to use neon signs that produce their favorite colors. John's favorite color is violet, while Jacob's favorite color is blue. Who would prefer to use an argon sign? Hint: A neon light produces visible light by electroluminescence. In this process, neon or some other gas gives off light when an electric current passes through it. Other halogen gases besides neonincluding krypton and argonalso produce light in this way. The word "OPEN" in the sign below is a neon light. It is a long glass tube that contains neon gas. When electricity passes through the gas, it excites electrons of neon atoms, and the electrons jump to a higher energy level. As the excited electrons return to their original energy level, they give off visible light. Neon produces red light. Other gases produce light of different colors. For example, krypton produces violet light, and argon produces blue light.
