Is dividing by zero bad?
As much as we would like to have an answer for “what’s 1 divided by 0?” it’s sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be true, because anything times 0 is 0. Created by Sal Khan.
What causes sinkholes to form?
Sinkholes are formed when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the voids. Drought, along with resulting high groundwater withdrawals, can make conditions favorable for sinkholes to form.
How do sinkholes form naturally?
Natural sinkholes occur due to erosion or underground water. Sometimes the flow of water increases to a point when it washes away the underground structure of the land. And when the structure becomes too weak to support the surface of the earth, it collapses and opens up a hole.
Can we divide by zero?
We can’t share among zero people, and we can’t divide by 0. After dividing, can we multiply to get back again? But multiplying by 0 gives 0, so that won’t work. Once again, dividing by zero gives us difficulties! Okay, let us imagine we can divide by zero, and see what happens.
Why do sinkholes appear?
A lack of water can contribute to sinkholes, too. In some underground cavities, water may actually be holding up a thin overhang of earth. If that water level falls, the overhang has no support and collapses. Sinkholes appear all over the United States.
What is a dissolution sinkhole?
A dissolution or solution sinkhole is essentially a deep impression in the ground. These sinkholes usually have a thin overburden (if any), which washes away or is eroded. The now-exposed rock then progressively dissolves when it touches acidic water.
What is a cover collapse sinkhole made of?
The top layer of a cover-collapse sinkhole is usually a soft overburden, made of soil with a lot of clay in it. Over time, a small cavern forms underneath that soil. Opportunistic sediment takes advantage of the newly free real estate and starts spilling into the cavern — a process known as spalling.
