Why isn’t the Amazon River in the top for the highest hydropower potential
Earth ScienceAsked by: Jami Olson Is the Amazon river used for hydroelectricity? Hydropower is the dominant source of energy in the Amazon region, the world’s largest river basin and a hotspot for future hydropower development. However, a new study warns that in the coming decades, climate change-driven reductions in precipitation and river discharge will diminish the
How do they determine the “feels like” temperatures for weather data?
Weather & ForecastsDecoding “Feels Like” Temperature: What the Weather Report Really Means Ever glance at the weather forecast, see a temperature, and then step outside only to think, “Wait a minute, this feels nothing like what they said!”? You’re not alone. That’s because the plain old temperature is just one part of the story. What you really
What temperature do small meteorites have on impact
Earth ScienceAsked by: Theresa Miller How hot is a meteorite impact? Entry into the atmosphere When they plow through the atmosphere, meteors are heated to more than 3000 degrees Fahrenheit, and they glow. Meteors are not heated by friction, as is commonly thought. A phenomenon called ram pressure is at work. A meteor compresses air in
Why are South African mountains short and flat?
Earth ScienceAsked by: Theresa Miller These are a product of the glacial and geological history of the region. The flat hills are capped by hard, resistant dolerite. This is solidified lava that was forced between the horizontal strata of the sedimentary rocks (which make up most of the Karoos geology) through high pressure. Why are mountains
Why do cold-core lows slope towards the cold air with heigth? How to show mathematically that wind intensifies with height in this case?
Weather & ForecastsWhy Cold-Core Lows Lean Towards the Chill: A Weather Geek’s Explanation Okay, so weather, right? It’s this crazy dance of hot and cold, high and low, and sometimes, it throws us curveballs like cold-core lows. Ever wonder why these systems, unlike hurricanes, are the strongest way up high and seem to slant towards the colder
