how was america populated?
During the second half of the 20th Century, a consensus emerged among North American archaeologists that the Clovis people had been the first to reach the Americas, about 11,500 years ago. This is the way America got populated.
What are major changes occurred in America's population?In 2006, America's population reached 300,000,000 inhabitants. According to the estimates of the US Census Bureau, at the end of 2019 the American population will exceed 330 million people. As can be seen, it is a population in constant increase, both for its positive birth rate and for the high rates of immigration that arrive in the country every year. With these numbers, a percentage of annual population growth of 0.62% is determined.
This amount of population makes the United States the third most populated country in the world, only behind China and India (which have 1.4 billion and 1.35 billion inhabitants, respectively).

Explanation:
What can people do to prevent desertification in the future?.
Planting more trees - the roots of trees hold the soil together and help to reduce soil erosion from wind and rain.
Improving the quality of the soil - this can be managed by encouraging people to reduce the number of grazing animals they have and grow crops instead. The animal manure can be used to fertilise the crops grown. Growing crops in this way can improve the quality of the soil as it is held together by the roots of plants and protected from erosion. This type of farming is more sustainable.
Water management - water can be stored in earth dams in the wet season and used to irrigate crops during the dry season. This is an example of using appropriate technology to manage water supplies in the desert environment.
Magic stones (or bunds) are circles of stones placed on the ground to hold water on the soil rather than letting it run quickly over the surface.
Drip irrigation is where water drips slowly onto the ground from pin-sized holes in a hose lying on top of the soil. This minimises water loss, maximises effectiveness and can be delivered via a solar pump.

Which property or properties did you find most useful in the identification of the mineral samples? Which properties were less useful? Be specific in your explanation.
Answer:
Type your answer here.
Answer:
2. Why was it important to examine both the colour and the streak of your minerals?
Answer: Because the surface colour of individual minerals can vary considerably but the streak colour is vertually constant & is therefore more characteristic of the mineral.
3. Is lustre a good characteristic to use for the
identification of minerals? Why or why not?
Answer: Lustre can vary within a particular
mineral - calcite might be vitreous or it may be
dull. Using lustre for identity often requires a
fresh surface if the mineral in anyway oxidises.
4. You have been given a sample of quartz, which has a hardness of 7. How can you use this mineral to determine the hardness of other minerals?
Answer: If the quartz can scratch another mineral, you know that mineral has a hardnessof less than 7. If the quartz is scratched by another mineral, you know that mineral has a hardness of greater than 7.
6. Which property or properties did you find most useful in the identification of the mineral samples? Which properties were less useful? Be specific in your explanation.
Answer: The most useful is hardness, fracture, cleavage, streak & sometimes crystal habit. The least useful is colour.
