Answer:
Explanation:
There are two dominant theories:
The inside-out model proposes that the Earth formed with trace amounts of water structurally bonded to the minerals in the mantle. This water makes its way to the Earth’s surface through volcanic processes.
The outside-in model proposes that the Earth formed without water, which came with other volatiles from the meteorites or comets that bombarded the young planet. This water was probably mixed into the upper layers of the Earth and was later brought to the surface through volcanism.
Answer: The halocline refers to the region below the mixed layer where the salinity changes as you move deeper underwater.
Answer:Roman Agriculture describes the farming practices of ancient Rome, an era that lasted 1000 years. From humble beginnings, the Roman Republic (509 BCE to 27 BCE) and empire (27 BCE to 476 CE) expanded to rule much of Europe, northern Africa, and the Middle East and thus comprised a large number of agricultural environments of which the Mediterranean climate of dry, hot summers and cool, rainy winters was the most common. Within the Mediterranean area, a triad of crops was most important: grains, olives, and grapes.
The great majority of the people ruled by Rome were engaged in agriculture. From a beginning of small, largely self-sufficient landowners, rural society became dominated by latifundium, large estates owned by the wealthy and utilizing mostly slave labor. The growth in the urban population, especially of the city of Rome, required the development of commercial markets and long-distance trade in agricultural products, especially grain, to supply the people in the cities with food.
