How did Bernard Palissy discover the water cycle? Palissy was the first person to consider the water cycle. When he observed some coastal areas, he found out it had salt water and fresh water. He presumed the fresh water was coming from the rainfall. How did we discover the water cycle? The Earth’s water cycle […]
What is polyatomic ion give example?
What is polyatomic ion give example? Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit. What is the […]
What other quantity is your slope equal to?
What other quantity is your slope equal to? The slope is representing the change in v over the change in time. By definition, this is the acceleration. Also more than just a gimmick, it’s geometry’s way of showing us how variables not only relate to one another, but how they can represent the rate of […]
How can longshore drift be stopped?
How can longshore drift be stopped? Groynes control beach material and prevent undermining of the promenade seawall. Groynes interrupt wave action and protect the beach from being washed away by longshore drift. Longshore drift is the wave action that slowly erodes the beach. Is longshore drift erosion or deposition? The material is transported through suspension, […]
Does siliceous ooze dissolve?
Does siliceous ooze dissolve? Siliceous oozes bracket the carbonate belt and blend with pelagic clays farther north and south. Because siliceous skeletons dissolve so quickly in seawater, only the more robust skeletal remains are found in the siliceous oozes. What is it called when siliceous ooze Lithifies? When thick deposits of diatomic rich ooze accumulates […]

The 13 Essential Friendship Traits I am trustworthy. I am honest with others. I am generally very dependable. I am loyal to the people I care about. […]
Why do we use thin gold foil?
Why do we use thin gold foil? For the scattering experiment, Rutherford wanted a metal sheet which could be as thin as possible. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford selected a gold foil for his alpha-ray scattering experiment. What was most […]
Is it possible to increase the temperature of a gas without giving it heat?
Is it possible to increase the temperature of a gas without giving it heat? Yes, during adiabatic compression the temperature of a gas increases while no heat is given to it. In compression work is done on the gas i.e. , work done is negative. Hence, internal energy of the gas increases due to which […]
How is flux generated?
How is flux generated? When a coil of wire is moved through a magnetic field a voltage is generated which depends on the magnetic flux through the area of the coil. Electric motors and generators apply Faraday’s law to coils which rotate in a magnetic field as depicted in Figure 3. In this example the […]
What is an example of a confirmation bias?
What is an example of a confirmation bias? Confirmation biases impact how we gather information, but they also influence how we interpret and recall information. For example, people who support or oppose a particular issue will not only seek information to support it, they will also interpret news stories in a way that upholds their […]
