Answer: Mining is an activity which the earth is dig to obtain minerals and oil reservoirs.
Explanation:
The two environmental consequences that are responsible for filling the valleys are soil erosion and downstream mining causing the contamination of the neighboring water source. Soil erosion is resultant of the mining activity causing the trees to be uprooting from their site and making soil prone to the affect of physical factors like wind and water.
Answer:
the 9 percent claim is demonstrably false on a number of levels. First, the entire brain is active all the time. The brain is an organ. Its living neurons, and the cells that support them, are always doing something. (Where’s the “you only use 9 percent of your spleen” myth?) Joe LeDoux, a professor of neuroscience and psychology at NYU, thinks that people today may be thrown off by the “blobs”—the dispersed markers of high brain activity—seen in functional magnetic resonance imaging (fMRI) of the human brain. These blobs are often what people are talking about when they refer to the brain “lighting up.”
Say you’re watching a movie in an fMRI scanner. Certain areas of your brain—the auditory and visual cortices, for instance—will be significantly more active than others; and that activity will show up as colored splotches when the fMRI images are later analyzed. These blobs of significant activity usually cover small portions of the brain image, often less than 10 percent, which could make it seem, to the casual observer, that the rest of the brain is idling. But, as LeDoux put it to me in an email, “the brain could be one hundred percent active during a task with only a small percentage of brain activity unique to the task.” This kind of imaging highlights big differences in regional brain activity, not everything the brain is doing.
In fact, the entire premise of only “using” a certain proportion of your brain is misguided. When your brain works on a problem—turning light that hits your retina into an image, or preparing to reach for a pint of beer, or solving an algebra problem—its effectiveness is as much a question of “where” and “when” as it is of “how much.” Certain regions of the brain are more specialized than others to deal with certain tasks, and most behavior depends on tight temporal coordination between those regions. Your visual system helps you locate that pint of beer, and your motor system gets your hand around it. The idea that swaths of the brain are stagnant pudding while one section does all the work is silly. The brain is a complex, constantly multi-tasking network of tissue.
Explanation:
Since WWII, Germany's eastern territories became apart of Poland. "Central Germany" is usually defined as being apart of the federal states of Saxony Thuringia and Saxony-Anhalt. It has even been said to be apart of a smaller part of this region, such as the metropolitan area of Leipzig and Halle as well as surrounding countries.
Answer:
2.656 km
Explanation:
Velocity of sound in the air = 332 m/s
time t= 8 sec
=2656 meters =2.656 km
therefore, distance = 2.656 km
Florida has lightening quite often because
Florida receives a lot of heat through out the year, air close the ground is warmed and frequent sea breezes (Florida is surrounded by seas and oceans) provide the necessary lift and moisture for the formation of thunderstorms. This why lightning is common Florida
They have less-runny lava, meaning that it doesn't travel as far before cooling, meaning that the layers build up more steeply, but don't go out as far. You also get layers of ash on the composite volcano to help build it up too
