How do volcanologists predict volcanoes? Earthquakes. Moving magma shakes the ground, so the number and size of earthquakes increases before an eruption. A volcano that is about to erupt may produce a sequence of earthquakes. Scientists use seismographs that record the length and strength of each earthquake to try to determine if an eruption is […]
Do live rocks die?
Do live rocks die? During the shipping process of all live rock, either pre-cured or uncured, some die-off will occur. For this reason, all live rock must be cured again, before it is placed in aquariums that contain fish, corals, or other marine animals. Will cold water kill live rock? Member. Yes, live rock can […]
Can a referee change his decision after final whistle?
Can a referee change his decision after final whistle? The referee may only change a decision on realising that it is incorrect or, at his discretion, on the advice of an assistant referee or the fourth official, provided that he has not restarted play or terminated the match. If play has not restarted, the referee […]

The FAA permits private pilots to share flight expenses with passengers as well as get paid for a limited number of jobs like towing gliders or being an aircraft salesman. But if you think about it, your […]
What is the importance of communicating your research study to others?
What is the importance of communicating your research study to others? Moreover, by communicating research results with colleagues in the scientific community, we allow ourselves to receive credit for doing the work, connect with others doing similar work thereby leading to new collaborations, and establish our results within the scientific knowledge base that future research […]
Does grass stop erosion?
Does grass stop erosion? Grasses native to your region will help build soil stability. Native grasses grow long roots that tie the topsoil and subsoil together. Buffer strips, or swathes of native species, are a great way to reduce erosion and sedimentation. An added bonus is using plants that can attract pollinators and increase biodiversity. […]
How do you calculate the change in liquid temperature?
How do you calculate the change in liquid temperature? This is easy. You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees […]
Which best describes thermionic emission?
Which best describes thermionic emission? Thermionic emission is the emission of electrons from a heated metal (cathode). As the temperature increases, the surface electrons gain energy. The energy acquired by the surface electrons allows them to move a short distance off the surface thus resulting in emission. Where is the focusing cup located? A focusing […]
Does sonar affect fish?
Does sonar affect fish? It is a finding that Popper says “should not be extrapolated to other fish species or the effects of other sound sources.” There is considerable concern that human-produced (anthropogenic) sounds added to the environment could have damaging effects on marine life. What is the basic principle of sonar? Sonar are electronic […]
