If the Earth were a smooth spheroid, how deep would the ocean be?
Earth scienceAsked by: Anthony Carrick The Earth’s oceans contain an estimate 1.332 billion cubic kilometres of water and the planet has a total surface area of 510.1 million square kilometres. That means, if evenly spread over a smooth sphere of that surface area, it would be covered by an ocean to the depth of 2.611 kilometres.
What is the physical meaning of the von Kármán constant?
Earth scienceAsked by: Anthony Carrick What is the value of Karman constant? The best estimate for the von Kármán constant in turbulent pipe flow is found to be 0.40±0.02. What is von Karman equation? The Von Karman equation introduced a system of two fourth order elliptic nonlinear partial differential equations which can be used to describe
When a tectonic plate subducts, does any of the subducted material melt, or is it just the mantle above the subducted slab that melts?
Earth scienceAsked by: Maria Molina What happens to a subducting plate after it Subducts? Once initiated, stable subduction is driven mostly by the negative buoyancy of the dense subducting lithosphere. The slab sinks into the mantle largely under its weight. Earthquakes are common along the subduction zone, and fluids released by the subducting plate trigger volcanism
What happens if it rains above the boiling point of water?
Earth scienceAsked by: Maria Molina It will depend on how the temperature and humidity change as the raindrops approach the bottom of the column. If the air is hothot‘Warm’ is used to explain the temperature below average. but ‘hot’ describes the temperature of objects especially in heat condition. Why is the boiling point lower when it
The seriousness of global warming/ climate change?
Earth scienceAsked by: Melissa Suddarth Earth Will Continue to Warm and the Effects Will Be Profound The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the duration and intensity of tropical storms. How does global warming affect climate change? As the earth’s
Could the recent temperature anomalies in the arctic be used as a proxy measure of global heating?
Earth scienceAsked by: Melissa Suddarth Why are temperature anomalies typically used in global temperature calculations? Anomalies more accurately describe climate variability over larger areas than absolute temperatures do, and they give a frame of reference that allows more meaningful comparisons between locations and more accurate calculations of temperature trends. What happens when temperature anomaly occurs? A
How different can microclimates be than their surrounding areas?
Earth scienceAsked by: Ryan Doshi What might cause one microclimate to differ from another? Microclimates are caused by local differences in the amount of heat or water received or trapped near the surface. A microclimate may differ from its surroundings by receiving more energy, so it is a little warmer than its surroundings. Why do urban
How does elevation affect the amount of rainfall received?
Earth scienceAsked by: Ryan Doshi Precipitation is a lot more common where there are higher elevations because the cooler weather and atmosphere cannot hold in as much condensation, causing it to rain or snow more often. In lower elevations, where it is more humid, moisture becomes trapped in the atmosphere easier, causing it rain less. How
How can I learn to spot fossils and fossil-bearing rocks on the Jurassic coast?
Earth scienceAsked by: Tyra Ellis Is it easy to find fossils on Jurassic Coast? Fossils can come from almost anywhere along the Jurassic Coast, but they are mostly quite hard to find and in some places fossil collecting is not allowed without permission. For any beginner, the beaches between Charmouth and Lyme Regis are the best
When sea water evaporates does it carry small amounts of salt into the atmosphere?
Earth scienceAsked by: Tyra Ellis When water evaporates (one molecule at a time), only pure water returns to the atmosphere. Salt and other impurities are left behind. What happens to the salt when sea water evaporates? When ocean saltwater evaporates, the salt in the water is left in the water. This causes the saltwater to become
