Drainage basin

There are smaller sets, described as basin mano-metates, which show mainly a circular motion. These were used for smaller batches of foods and probably a larger variety of wild foods or spices. This type of technology was used with a one-handed mano which was used to apply pressure up the sides of the basin with the grain in between. These models would have been the most tiring and the least efficient for large batches of…

The Head-Smashed-In Buffalo Jump (HSI) has been known as an UNESCO Heritage Site located in Alberta, Canada. This bison jump is a known archaeological site, that preserves the early history of Plains First Nations (Brink et al. 1986) Aboriginal people who roamed the Plains understood the importance of resources and regional topography. By understanding how the environment functioned and thrived, Plains people were also able to monitor and develop a better understanding of buffalo mobility and…

1) Massive Oil Pipeline Leak under North Dakota Farmer’s Field The North Dakota farmer found an oil spill the size of seven football fields during harvesting the wheat. The farmer said that the crude was bubbling up out of the ground when he found it and the crude can be smelled for days before the tires of the combines were coated in it. The damage of the pipeline causes the oil spewing and bubbling six inches high. It was one of the largest spills recorded in the stated which was equal to…

of the North American continent. Uplift associated with mountain formation later moved these sediments thousands of feet upward and created the Colorado Plateau. The higher elevation has also resulted in greater precipitation in the Colorado River drainage area, but not enough to change the Grand Canyon area from being semi-arid. The uplift of the Colorado Plateau is uneven, and the Kaibab Plateau that Grand Canyon bisects is over a thousand feet higher at the North Rim than at the South Rim.…

The Mongols dominated Russia from 1240 to nearly the end of the of the 16th century CE. The empire conquered by Genghis Khan was split after his death among his heirs and eventually divided into four smaller, though not insignificant Khanates. According to David O. Morgan the Great Khanate in and around China, the Ilkhanate of Persia, Iraq, and parts of Anatolia, the Chagatai Khanate of Central Asia, and the Golden Horde that controlled much of the Western and Southern parts of Russia. Due to…

In 2017, the fee schedule is divided into two parts, residential and non-residential area, owners of residential area only need to pay a monthly fee based on how big their…

80% of this is groundwater (Public Services, 2010). More groundwater pumping leads to localized over-drafting which in turn causes saltwater intrusion into any of its six water basins: Parajo Valley, Prunedale, Salinas Valley, Marina Fort Ord, Carmel, or El Toro (Public Services, 2010). Arguably the most important basin is the Salinas Valley because it is home to the Salinas River which not only supplies water for the surrounding agricultural fields, but also can also easily overflow and kill…

Lake Erie is one of the largest bodies of fresh water on the plant, and it provides drinking water to over 11 million people. Unfortunately, the large body of water is under attack, and the offender, is the very people depending on it. Over the past couple of years Lake Erie has been assaulted with worsening toxic algae blooms. As a result, in 2014, the city of Toledo was unable to consume the tap water without fear of becoming sick. Now, how is it the people 's fault that this is occurring?…

In the 21st century, global warming, which is caused by the increase of carbon dioxide gases that forms from burning fuels in the atmosphere, is a serious threat to the Earth. As National Renewable Energy Laboratory (2006) statistics show, energy consumption is done principally by buildings in the U.S. This research intends to decrease the percentage of carbon emission by developing zero carbon homes. Berry,S. et. al. (2013) define zero carbon homes as having no need for fossil fuel for heating…
