Does vegetation contribute to long-term carbon sequestration?
Earth scienceAsked by: Peggy Dunbar So yes, vegetation can contribute to long-term carbon sequestration, although primarily by mechanisms other than the river transport and ocean deposition you proposed. Show activity on this post. Plant matter decomposes, partly it is digested aerobically (releasing CO2 again) but partly it forms humic acids. What factors influence carbon sequestration? Uptake
If the distance between Earth and the moon were changed, would the effects be immediate?
Earth scienceAsked by: Peggy Dunbar What would happen if you decrease the distance between the Earth and the Moon slightly? If the satellite were slightly closer, the tidal bulge would grow. Low tides would be lower and high tides would be higher and any low lying coastline would be flooded. If the Moon got much closer,
Does a table summarizing basic details of significant operational weather models exist?
Earth scienceAsked by: Danielle Cottle What is an operational weather model? Operational forecasting involves generating weather forecasts that people use to make decisions, from the daily choice of whether or not to carry an umbrella to life-or-death decisions about whether to issue evacuation orders. How accurate are weather forecast models? The Short Answer: A seven-day forecast
Websites providing visual weather data
Earth scienceAsked by: Danielle Cottle What website shows weather accurately? AccuWeather is Most Accurate Source of Weather Forecasts and Warnings in the World, Recognized in New Proof of Performance Results. Where can I collect weather data? They include weather balloons, satellites, and radar (Figure below). Weather stations collect data on land and sea. Weather balloons, satellites,
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 ForecastingAsked by: Jami Olson We calculate a ‘feels like’ temperature by taking into account the expected air temperature, relative humidity and the strength of the wind at around 5 feet off the ground (the typical height of a human face!), combined with our understanding of how heat is lost from the human body during cold
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
Do northern lights (aurora borealis) show the same visual activity all along their visible latitude range?
AurorasAsked by: Alex Santiago What latitude are the northern lights visible? between 60 and 75 degrees of They usually occur between 60 and 75 degrees of latitude, which covers northern parts of Canada, Norway, Sweden, Finland, Alaska and Russia as well as all of Iceland. Can you see aurora borealis in other latitudes of the
Why do cold-core lows slope towards the cold air with heigth? How to show mathematically that wind intensifies with height in this case?
MeteorologyAsked by: Alex Santiago Why does cold core low intensify with height? It is a low pressure system that strengthens with height in accordance with the thermal wind relationship. If a weak surface circulation forms in response to such a feature at subtropical latitudes of the eastern north Pacific or north Indian oceans, it is
