Why do tropical cyclones get more attention than extratropical cyclones?
Earth ScienceAsked by: Edgar Ayala Why are tropical cyclones more powerful than temperate cyclones? A tropical cyclone has an effect on a comparatively smaller area than a Temperate cyclone. The velocity of wind in a tropical cyclone is much higher and it is more damaging. Tropical Cyclone forms only on seas with temperature more than 26-27degree
Could Australia’s bushfires aerosols actually decrease global temperature?
Safety & HazardsCould the Aussie Bushfires Actually Have Cooled the Planet? Seriously? Remember the Black Summer? Those horrific Australian bushfires of 2019-2020? Seemed like half the country was ablaze. Beyond the immediate devastation – the loss of wildlife, homes, and, tragically, lives – scientists have been grappling with a mind-bending question: could all that smoke have actually
Is the Grand Canyon the “greatest” canyon in the world?
Earth ScienceAsked by: Wendy Irvin Is the Grand Canyon the biggest canyon in the world? Grand Canyon occupies a large portion of northern Arizona and extends about 270 miles from Lees Ferry (just southwest of Lake Powell) to the Grand Wash Cliffs (just east of Lake Mead)–the longest canyon in the world. “Only” a mile a
How long did it take for Earth’s magnetic field to first appear?
Earth ScienceAsked by: Albana Ying How long ago did Earth’s magnetic field form? 3.5 billion years ago Multiple lines of evidence have shown that the Earth’s magnetic field existed at least 3.5 billion years ago. However, the planet’s core is thought to have started solidifying just 1 billion years ago, meaning that the magnetic field must
How do I get the velocity of the P-wave or S-wave without using the travel time graph?
Earth ScienceAsked by: Albana Ying How do you find the velocity of P and S waves? The velocity of a P or S wave is a function of the physical properties of the rock the wave is traveling through.Velocity P wave = ((B + 1.3G)/Density)1/2, where: B = the bulk modulus – the resistance to change
