Sinkholes; how do sinkholes form?

Imagine the ground beneath your feet or your house suddenly collapsing and forming a large hole in the ground. It's a terrifying thought. Sinkholes are uncommon, but when they do develop, they can be fatal. Sinkholes form when the ground underneath the land surface is unable to support it. Sinkholes can occur for a variety of causes; continue reading to learn more about them. Sinkholes are widespread in areas where the geology beneath the land surface contains limestone, carbonate rock, salt beds, or rocks that can be dissolved naturally by groundwater passing through them. Underground caves and caverns form as the rock degrades. Sinkholes are spectacular because the land normally remains intact for a long time until the subsurface areas get too large. A abrupt collapse of the ground surface can occur if there is insufficient support for the land above the voids. Formation of sinkhole; Image credits - cartleton.edu What is a "sinkhole"? When it rains, water stays inside t

Airbags; how do they work?

Even if the driver secured properly, an accident would occur at high speeds if there was no airbag. It is a significant engineering challenge to bring the human body to a stop from a high speed in less than 100 milliseconds without causing significant bodily harm. Let's have a better grasp of this life-saving technology by looking at the mechanism of airbag inflation, which is triggered by chemical explosions. Seatbelts are meant to keep the human body from moving, but they can cause internal organ injury if they apply too much stress on the chest area during an accident. Modern seat belts use a torsion bar to slightly release the seat belt in the event of a large impact on the chest. This action causes the upper body to move forward somewhat, but as the torsion bar is released, the upper body's movement is stopped. Working Mechanism of Airbags, Image credit; whyflies.org Please notice that the sear belt only arrests the motion of your upper body, omitting your neck and head, w

What is MSG, is it actually bad for you?

Monosodium glutamate MSG is a flavor enhancer that is commonly used in restaurant dishes, canned vegetables, soups, deli meats, and other foods. MSG has been designated as a generally recognized as safe food additive by the US Food and Drug Administration (FDA). However, its application is still up for discussion. As a result, the FDA requires MSG to be stated on the label when it is added to food. For many years, MSG has been utilized as a food ingredient. During this time, the FDA has received numerous reports of alarming reactions that have been linked to MSG-containing foods. The MSG symptom complex includes the following reactions: Headache Flushing Sweating Face pressure or tightness Lack of feeling (numbness), tingling or burning in the face, neck and other areas Quick, fluttering heartbeats Chest pain Feeling sick (nausea) Weakness However, no conclusive evidence of a relationship between MSG and these symptoms has been discovered by experts. However, researchers acknowledge th
