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.
As the two plates collide,the denserr oceanic plate will subduct under the less dense continential plate, causing the continential plate to arch up and form a mountain range.
Let's look into it one by one:
A. An underwater mountain range will will run along the boundary on the oceanic plate. - This is false.
As the oceanic plate subducts under the continential plate, there is no chance for the denser material to accumulate while subducting. What would be find instead is ocean trench.
B. A mountain range will form in the middle of the continental plate. - This is false.
Although pressure will be applied and there would be stress accumulating on the continential plate, the middle is very unlikely to be affected.
C. A mountain range will run along the boundary on the continental plate. - This is true.
As the subduction happens, the continential plate will accumulate as it is less dense. The rock would fold up to form mountain ranges. For example, Rockies is one off the mountain range along the plate.
D. A chain of islands will form along the boundary of the oceanic plate. - This is false.
Similarly to A. it is not possible for the plate to accumulate when it slides under the other plate.
Therefore the answer is C. A mountain range will run along the boundary on the continental plate.
Hope it helps!
D. Obviously because it was large and they didn't have a lot of supplies to go across also it was very deep.
erode means to wear away slowly
And scientists say it will take natural processes 6,000 years to refill the reservoir
