Answer:
The United States has a good amount of freshwater supply over most of the territory, because the American territory is ripe with lakes, rivers, streams, and groundwater.
The quality of these water sources varies from area to area, and many water bodies have been deeply polluted by human activity. However, the United States is a developed country with generally good water treatment facilities.
Notwithstanding, the United States faces two important challenges: one is the growing population of the country, which will put more pressure on freshwater sources in the future. The other one is that a few areas of the country are devoid of water supply sources, and they are among the fastest growing regions of the U.S (Nevada, Arizona, New Mexico). This poises a great challenge for U.S. authorities in the near future.
The peninsular rivers are seasonal because they depend on rainfall for water.
1.We have access to space to see it is round
2. We have 24 hour time zones. How could it be noon in one place and midnight in the other?
3.We are able to study lunar eclipses and see how they work (greeks discovered the earth is round with that method.).
4. Why do ships slowly sink into the distance? Exactly
5. Surveying other planets.
Answer:
Reducing the hoofed animal population, which benefits the natural surroundings and smaller herbivores.
Explanation:
It depends on the latitude where you measure it.
It's about 69 miles on the equator, and it shrinks to zero at the poles.
In general, at any latitude,
Distance covered by 1 degree of longitude =
<em> (69 miles) x [ cosine(latitude where it's measured) ]</em>
