Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.

Answer:
<em>Natural causes of earthquakes </em>
Explanation:
Earthquakes are triggered<em> by the rapid energy release in some of the Earth's small rocks. Energy can be released by elastic stress, gravity, chemical reactions, or even massive body motion.</em>
The release of elastic strain is the most important cause of all these, because this form of energy is the only sort that can be stored in sufficient quantities on Earth to create major disruptions. This type of energy release related earthquakes is called tectonic earthquakes.
