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:
The forces which originate from within the earth's crust or inside the earth are called internal or endogenetic forces. The sources providing them energy are the internal heat, chemical reactions taking place within the earth, and the transfer of rock materials on the earth's surface by external forces.

Answer:
The Democratic Republic of the Congo (DRC), the second-largest country in Africa, has been mired in conflict for decades. A country of paradoxes, it is a land rich in natural resources, but its people are among the poorest in the world.
While the DRC has vast amounts of oil, diamonds, gold, and other natural resources, a majority of the population — about 64% — is considered extremely poor and lives on less than $1.90 a day, according to World Bank estimates.
The country is fraught with political instability, armed clashes, and human rights violations. Conflict erupted in 2016 in the Kasai region, which includes five provinces in the center of the country. It is yet another instance of fighting between the military and splintered ethnic militias. Nationally, 2.1 million people were newly displaced in 2017 and 2018, making the DRC the African country with the highest number of internally displaced people — 4.5 million. About 13 million people lack adequate food, including more than 1.3 million children under 5 affected by severe acute malnutrition.
Ebola alert — July 17, 2019: The World Health Organization has declared an Ebola outbreak in northeast DRC that began in August 2018 to be a public health emergency of international concern. WHO chief Tedros Adhanom Ghebreyesus called for countries to commit more resources to fight the disease. His announcement came three days after a case of Ebola was confirmed in Goma, the capital of Northern Kivu province, which is a transportation hub and home to 1 million people.
Ebola briefly broke out in May 2018 in northwestern DRC, then the deadly virus resurfaced in August in the northeast. This is the 10th outbreak of the deadly viral disease in the DRC since it was identified in the 1970s. Earlier outbreaks were quickly contained and didn’t spread beyond isolated rural communities.
