Answer:

Sea floor spreading theory is given Harry Hess the line of evidence that support this are given as under.

Explanation:

Evidence from Molten Matter  

In the 1960s scientists found that there is a presence of new materials from below that need the lava to be uplifted and spread along the boundaries of mid-oceanic ridges i.e the lava or magma spreads through the active plate margins of both plates. The red sea is newly formed is an example of spreading, <u>(a process of oceanic basin creation)</u>.

Evidence from Magnetic strips

The magnetism of the earth helped the scientists study the process of seafloor spreading as the newly formed lava gets deposited on either side of the ridges it takes the magnetic properties of the earth. The ocean floor is divided into strips of north and south after cooling.

Active and passive plate margins.  

The tri-junction of plates and newly discovered plate like that od red sea and splitting of the rift valley and transform faults. Movement of continents away from each other. Examples include Eastern pacific rise and Mid Atlantic ridge.

Why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS?
Sholpan [36]

Answer:

According to (hrw dot com) the “Abstinence-Only HIV/AIDS Programs” in Uganda in the early 200x is called The Less They Know, the Better. Why the people there do not need to know so much about HIV, but they need just to follow the Abstinence ? “We don't think abstinence is really working in our communities. We work with children in primary five through seven who are engaging in sexual activities. We always come with the message to delay sexual debut. But for most children here, this is not enough.” - The youth leader of the program said.

So, the main reason why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS is: the people for whom the propaganda is done are mostly children above 10, who tend to start having sex at an early age. Uganda is home to nearly 1 million children orphaned by HIV/AIDS, many of them at high risk of HIV infection themselves.

“Abstinence Until Marriage" is the meaning of the Abstinence-Only HIV/AIDS Programs. The content of the propaganda is teaching that abstaining from sex until marriage is the only effective method of HIV prevention and that marriage between a man and a woman is the expected standard of human sexual behavior.

The other reasons are:

- Demographic and health surveys show that over half of Ugandan girls have had sex by age seventeen, usually with someone older.

- Among girls who marry before the age of eighteen, most marry men who have been sexually active for several years, often without having used condoms.

And there is the biggest problem for Uganda related to poverty: Ss in all countries, AIDS in Uganda is a disease of poverty. Many Ugandans live on less than U.S.$1 per day, a situation that has been exacerbated by decades of political violence and civil war. New HIV cases occur among girls trading sex for school fees, women enduring violent marriages because they lack economic independence, and orphans being pushed onto the street and sexually exploited.
