Equilibrium condition for Kelvin’s Vapor Pressure-curvature equation
Earth scienceAsked by: Crystal White What does the Kelvin equation tell us about? The Kelvin equation1 relates the equilibrium vapour pressure of a liquid to the curvature of the liquid–vapour interface. It predicts that undersaturated vapours will condense in channels of sufficiently small dimensions.16 апр. 1981 What is Kelvin equation in surface chemistry? The Kelvin equation

Can continental plates collide and fuse together without an orogenic band or magmatic arc or at the junction?
Earth scienceAsked by: Edgar Ayala Can tectonic plates fuse together? Plates occasionally collide and fuse, or they can break apart to form new ones. When the latter plates break apart, a plume of hot rock can rise from deep within the Earth’s interior, which can cause massive volcanic activity on the surface. What happens when continental

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

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

What is the most powerful natural catastrophic event on record?
Earth scienceAsked by: Karen Handy Excessive rainfall over central China in July and August of 1931 triggered the most deadly natural disaster in world history — the Central China floods of 1931. What is the most powerful natural event? La Garita Caldera Eruption The most powerful eruption in the observable history of our planet the eruption

Can we define “drainage density” for a soil column (point-scale)?
Earth scienceAsked by: Karen Handy How is drainage density determined? Drainage density is a measurement of the sum of the channel lengths per unit area. It is generally expressed in terms of miles of channel per square mile. What is drainage density simple definition? The drainage density is the measure of the length of stream channel

How to estimate the settling time of atmospheric particulates as a function of aerodynamic size?
Earth scienceAsked by: Christina Cornwell What is the relationship between particle size and settling time? The settling velocity, and, as a result, settling time, are proportional to the diameter of the spherical particle squared. The larger the sphere diameter, the faster the particle will settle. The smaller the particle diameter, the longer it will stay suspended

Interpreting a geological map
Earth scienceAsked by: Christina Cornwell How is a geologic map interpreted? The purposes of a geologic map are to show the surface distributions of rock units, the locations of the interfaces or contacts between adjacent rock units, the locations of faults, and the orientations of various planar and linear elements. (Standard geologic symbols are shown in
