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: EXCESS NUTRIENTS FROM FERTILIZERS
Explanation: Fertilizer is an organic or synthetic chemical materials which contains certain nutrients or chemical compounds required by plants for proper growth and development.
Euthrophication is the process of increase in the plant population in water bodies such as Algae and other higher plant species due to the release of nutrients into water bodies. This nutrients can be washed through the flooding of farm lands,erosion etc. Example of fertilizers include livestock manures,Ammonium nitrogen fertilizer,Nitrate nitrogen fertilizer,Amide nitrogen fertilizer,Agricultural waste etc.
The reasons as to why the Indo-Europeans migrated to Europe were the better climate conditions, more grazing land and fertile soil, and overpopulation.
Explanation:
The Indo-Europeans were a group of people that formed and lived in the Eurasian Steppes, mostly in the lowlands of what is now Central Asia. Central Asia though was not offering the best living conditions, as the climate was harsh, fertile soil, was lacking, the grazing lands were limited, and the population of the Indo-Europeans was constantly growing. This made numerous groups of these people to migrate in several waves toward other regions, including Europe.
Being a war-like people and superior in combat, the Indo-Europeans found it easy to move into the European territories and settle in. The migration waves were mostly going through the lowlands north of the Black Sea, and through Anatolia and the Balkan Peninsula. Very quickly the Indo-Europeans managed to become dominant in Europe, establish their culture, language, and beliefs.
The main reason for migration were:
- overpopulation
- better grazing lands
- fertile soil
- better climate
Ethnic families that are believed to have originated from the Indo-Europeans are:
- Celtic people
- Germanic people
- Slavic people
- Baltic people
- Italic people
- Daco-Thracian people
- Illirian people etc.
