because it describe the relationship between the motion of an object and the forces acting on it.
1. Vog
The term vog comes from combining the words volcano and smog. The word itself is created to associate with pollution, as it is a natural pollution of the atmosphere. The vog represents the sulfur dioxide and the other gases and particles that the volcanoes release into the atmosphere when they erupt. These gases and particles further react with the moisture in the atmosphere and the oxygen while exposed to sunlight. This process causes a large natural pollution of the air in the area influenced by the volcanic activity.
2. Model
Steven Businger is a scientists that has devoted big portion of his career in examining the volcanoes and their activities. Most of his research has been on the Hawaii Islands and the volcanoes on them. With his vast experience and knowledge of the volcanic activities and their products, Businger managed to create a model that predicts how the smoke from the volcanoes spreads. This model has been very helpful as it can be used for warning the population on time, as well as using it for avoiding accidents, especially in the air traffic.
3. Sulfur dioxide
One of the gasses that is in largest quantities in the smoke produced by the volcanic eruptions is the sulfur dioxide. This gas is a natural polluter of the atmosphere, so once big amount of it is propelled into the atmosphere, it manages to have big effect over the area that is affected. It is a gas that is very harmful for the living organisms, thus for the human health as well. It is mostly damaging the respiratory system, managing to cause lot of damage that can easily be fatal if the amount of sulfur dioxide is high.
The correct answer is seismic waves.
A sudden movement of the Earth's crust followed by the production of seismic waves is known as an earthquake. The seismic waves travel outwards from the source. The sudden vibration or ground motion is generated due to a brisk discharge of accumulated energy.
The vibrations, which travel via Earth carrying the energy discharged at the time of an earthquake is known as seismic waves. The earthquakes are usually determined with a help of seismometer, called seismograph.
Indigestable food moves from the small intestine to the large intestine where water is absorbed back into the body. The waste is then passed through the rectum and excreted from the anus.
I would say the large intestine.
