The Neolithic revolution was the first agricultural revolution. It was a gradual change from nomadic hunting and gathering communities and bands to agriculture and settlement. This period is described as a "revolution" because it changed the way of life of communities which made the change. It occurred in different prehistoric human societies at different times. Many societies changed 9–7 thousand years ago.
The term refers to the general time period over which these developments took place. It also applies to the changes which took place: the adoption of early farming techniques, crop cultivation, and the domestication of animals. The Neolithic Revolution is important for developments in social organization and technology.
The Neolithic revolution led to living in permanent or semi-permanent settlements. Because of this fewer people led a nomadic lifestyle. To be able to know who the crops grown belonged to, the concept of land ownership was developed. The natural environment was changed, population densities grew, and people ate more vegetable and cereal foods in their diet. Hierarchies developed in society. Grain was stored, and could be traded. Surplus production from good crop yields helped societies survive bad years.
The answer is the ocean-continental convergence. This is where the gold of the Inca civilization come from.
The subtropical jet streams formate from cool and warm air masses that meet near the equator (close to the 30* Latitude).
Which of the following soil-building processes contributed most to making the shaded area on the map suitable for agriculture? Floods deposited rich silt over the land in a soil-building process that made the land fertile.
Answer:
A sediment deposit close to the continental rise having a coarse material overlaid by successively finer materials of non marine origin is called a turbidite.
.
Explanation:
Turbidity current is the movement of sediment laden water . It is caused by the high density nature of sediments . The current is prevalent in oceans and lakes and it one process that transport sediments from coastal areas to deep sea.
The sediments in the current makes the flow denser and very rapid. The rapid nature of the movement of this sediment laden water causes a kind of selective deposition in deep sea. The more coarse sediments are deposited before less coarse sediments. The sediments deposited fines upward. The coarsest sediments are found at the bottom and it fine upward.
Turbidites are sediments deposited by turbidity currents which gradually change from coarse grain to fine grain sediments. The continental rise is the boundary between continents and the deep part of the oceans. This area is usually laden with sediment deposited by turbidity current. The sediments laden water moves downhill.
