Answer:
the U.S. southwest
Explanation:
Aridosols are desert soils, where plant diversity is very low and often nonexistent. These soils are formed in arid and semi-arid regions, such as those found in the Southwestern United States. These soils occur due to the insufficient amount of precipitation in the region, in addition, due to the low vegetation cover, the rain that falls in the region, manages to leach the soluble salts of the soil, allowing them to drain into the deeper layers of the soil, where they can form carbonate, gypsum or saliferous horizons.
<u>Answer:</u>
If it is noon time at 70 degree west longitude, The solar time at 72 degree west longitude would be 12:08 p.m., at 65 degree west longitude time would be <u>11:40 a.m</u>., at 90 degree west longitude the time would be <u>12:40 p.m.</u> and at 110 degree east longitude the solar time would be <u>00:00 midnight</u>. This has been calculated with the formula that one degree is equal to 4 minutes.
Answer:
It took climate change, fertile river valleys, domestication of crops and animals so that the hunter-gatherers became sedentary farmers.
Explanation:
Initially, all humans were hunter-gatherers. This was due to multiple reasons, with one the biggest one probably being the climate which was not enabling good conditions for the hunter-gatherers to transform their lifestyle. All other conditions needed were stopped because of the climate conditions, so humans had to do what they could to survive in those conditions.
About 10 years ago though the bad climate conditions ended, or rather the Ice Age ended. This resulted in a much warmer climate, which in turn created much more water bodies like rivers and lakes, much more vegetation, and they contributed to the creation of much more fertile soil.
With these conditions in place, the humans quickly saw that there is huge potential in some plants and animals, so they started to farm them, select the ones with the best characteristics, and gradually producing enough food for themselves. With the food problem solved, humans didn't have the need to wonder around all the time, so they started abandoning the hunter-gatherer lifestyle and started settling in one place.
Answer:
Earthquakes
Explanation:
Earthquakes are caused by the movement along the fault, which is found near the boundaries of two tectonic plates. The specific fault where plates slide against each other is known as the transform fault.
The second one is A, amount of time
