I have a new situation: In the year 1630 during the month of January Captain Cook began his voyage from the port of Calais in Europe, which is in the Northern Hemisphere. His intention was  to find the mythical land in the Southern Hemisphere. After about eleven months of sailing, in December 1630, he reached Australia, which is indeed in the Southern Hemisphere. Thinking he finally reached the mythical  land, he commenced his return voyage to Europe on June,  1631, He reached Europe in the middle of the following year on July, 1632.  But I can use this background: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere.  What is an answer for this question: Did Australia exprience increased or decreased solar flux when Captain Cook reached Australia in 1630?

Answer: increased


I have a new situation: David is an environmental scientist. He needed to find causes of wildfires and suggest preventive measures. First, he visited a dense forest. He marked it as location A. Then he visited a grassland, which he marked as location B. After that, he visited a location where he did not find any sign of drought. He marked it as time A. He then visited the same location a year later, and found that the place was facing a severe drought. He marked it as time B.  But I can use this background: Wildfires occur when all the necessary elements of a fire triangle come together in a susceptible area: an ignition source is brought into contact with a combustible material such as vegetation, that is subjected to enough heat and has an adequate supply of oxygen from the ambient air. A high moisture content usually prevents ignition and slows propagation, because higher temperatures are needed to evaporate any water in the material and heat the material to its fire point. Dense forests usually provide more shade, resulting in lower ambient temperatures and greater humidity, and are therefore less susceptible to wildfires. Less dense material such as grasses and leaves are easier to ignite because they contain less water than denser material such as branches and trunks. Plants continuously lose water by evapotranspiration, but water loss is usually balanced by water absorbed from the soil, humidity, or rain. When this balance is not maintained, plants dry out and are therefore more flammable, often a consequence of droughts.A wildfire front is the portion sustaining continuous flaming combustion, where unburned material meets active flames, or the smoldering transition between unburned and burned material. As the front approaches, the fire heats both the surrounding air and woody material through convection and thermal radiation. First, wood is dried as water is vaporized at a temperature of 100 °C (212 °F). Next, the pyrolysis of wood at 230 °C (450 °F) releases flammable gases. Finally, wood can smoulder at 380 °C (720 °F) or, when heated sufficiently, ignite at 590 °C (1,000 °F). Even before the flames of a wildfire arrive at a particular location, heat transfer from the wildfire front warms the air to 800 °C (1,470 °F), which pre-heats and dries flammable materials, causing materials to ignite faster and allowing the fire to spread faster. High-temperature and long-duration surface wildfires may encourage flashover or torching: the drying of tree canopies and their subsequent ignition from...  What is an answer for this question: Would location B be less or more susceptible to wildfires than location A?

Answer: more


I have a new situation: Two neighboring towns used different approaches to agriculture. Big town used pesticides and fertilizers, while Small town applied permaculture principles and organic farming methods.  But I can use this background: Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick.  What is an answer for this question: Which town had less growth of water plants because of fertilizer?

Small
