In World Geography you will examine people, places, and environments at local, regional, national, and international scales from the spatial and ecological perspectives of geography. You will learn the influence of geography on events of the past and present with emphasis on contemporary issues. A significant portion of the course centers around the physical processes that shape patterns in the physical environment; the characteristics of major landforms, climates, and ecosystems and their interrelationships; the political, economic, and social processes that shape cultural patterns of regions; types and patterns of settlement; the distribution and movement of the world population; relationships among people, places, and environments; and the concept of region. You will analyze how location affects economic activities in different economic systems. You will identify the processes that influence political divisions on the planet and analyze how different points of view affect the development of public policies. You will compare how cultures shape the characteristics of regions and analyze the impact of technology and human modifications on the physical environment. You will use problem-solving and decision-making skills to ask and answer geographic questions.

Explanation:
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. The half-life is 50,000 years. Rock Layer E has undergone radioactive decay ONCE, how many daughter and parent isotopes are present in layer E?
Answer:
Explanation:
By definition, after a radio active decay, a parent isotope will create a daughter isotope.
Layer C is exactly one half-life from Layer E at 50000 years. So half of the original parent isotopes from Layer E would have decayed to form daughter isotopes. As C has 18 radioactive isotopes together, E should have 6 daughter and 6 parent isotopes.
Answer:
Explanation:
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. So the two layers are off by 50,000 years; equal to one half-life.
As Rock Layer E has undergone radioactive decay ONCE, each parent isotope forms one daughter isotope after the decay.
Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. So that represents an equal number of parent and daughter isotopes, i.e. 9 parent and 9 daughter isotopes.
So there are 9 parent and 0 daughter isotopes in layer E.

Describe two effective means of preventing the spread of malaria.
Answer:
There are two central blocking systems: Protective bed nets treated with long-lasting instinct poison prevent bites from malaria-infected mosquitoes and kill them. Nets should be available for free or at low prices because of high subsidies. There should be one net per two people who are at risk of being infected.
Explanation:
Presently, Mosquito control and mosquito-bite prevention are the two key approaches used to prevent malaria.
How can you prevent the spread of malaria?Personal protection measures against mosquito bites- Malaria is primarily transmitted at night since the majority of Anopheles mosquitoes bite at night. Wearing clothing that covers the majority of the body, using insect repellent on exposed skin, and using mosquito bed nets are all ways to prevent mosquito bites. Age and status affect the kind and strength of repellents.Mosquito prevention- The effectiveness of vector control strategies is dependent on the vector species, the biology of the mosquito, the epidemiological situation, the cost, and the acceptability to the people. The primary current approaches concentrate on reducing human-mosquito interaction and eliminating larvae through environmental management.To learn more about malaria
