How do we know the asteroids formed at the same time as earth?
Earth scienceAsked by: Frank Dahlkemper The fact that the overwhelming majority of celestial objects within our solar system orbit in a like manner (same direction as the Sun’s rotation) is observational evidence that they formed at about the same time from the same processes. How do we know what asteroids are made of? While in orbit,

Regarding forest fire season and using robotic devices for proactive efforts before any fires
Earth scienceAsked by: Frank Dahlkemper What technology is used to prevent wildfires? While firefighting has largely remained unchanged, high-tech solutions are changing how wildfires are battled. Technologies, such as drones, robots, and satellites, are all being used to detect, impede, and douse fires. What data is important when fighting forest fires? Specialists consider air temperature, humidity,

How accurately can a tsunami be predicted? Have there been any successful evacuations?
Earth scienceAsked by: Stephanie Walker Can tsunamis be accurately predicted? Like the earthquakes that generate most tsunamis, scientists cannot predict when and where the next tsunami will strike. How can you predict if a tsunami is coming? Early warning signs of a tsunami One of the signs of a potential tsunami is the occurrence of a

Eliminating range folding error in doppler radar returns
Earth scienceAsked by: Stephanie Walker What causes range folding? range_folding. Range folding takes place when a radar echo from outside the radar’s maximum unambiguous range gets displayed incorrectly within the radar range: The maximum unambiguous range is determined by the PRF (pulse repetition frequency). What are the factors affecting range resolution of a radar? Range resolution

At what humidity does it start to rain?
Earth scienceAsked by: Jack Soulsby 100%60%, but over time, the humidity will increase. Does 100% humidity mean it is raining? Must it be raining when the humidity reaches 100%? A relative humidty measurement of 100% does not necessarily mean that rain is falling. It just means that the air is holding as much moisture as it

Timescale of the biological pump？
Earth scienceAsked by: Carson Saunders What is the biological pump and how does it work? The biological pump is the set of processes by which inorganic carbon (e.g., carbon dioxide) is fixed into organic matter via photosynthesis and then sequestered away from the atmosphere generally by transport into the deep ocean. What does the biological pump

Can cooled/hardened lava rock return to a molten state?
Earth scienceAsked by: Carson Saunders Yes, at least partially. It is important to remember that a “rock” usually does not have a single melting point. It melts over an interval. Can lava turn back into magma? Magma can be melted or partially melted crust, also old volcanic crust, so if old lava somehow re-enters a magma

Is the Younger Dryas associated with an extinction event?
Earth scienceAsked by: Rene Kielholz The Younger Dryas (YD) impact hypothesis is a recent theory that suggests that a cometary or meteoritic body or bodies hit and/or exploded over North America 12,900 years ago, causing the YD climate episode, extinction of Pleistocene megafauna, demise of the Clovis archeological culture, and a range of other effects. What

Why are weather kites no longer used (much) operationally?
Earth scienceAsked by: Rene Kielholz How are kites used for weather? Each kite train carried a meteorgraph, a combined instrument package which recorded temperature, wind velocity, humidity, and barometric pressure. While weather kites have been largely superseded, they still have their uses, and are still employed by the British Antarctic Survey. How did they predict the
