What are the reasons for why ancient indo-Europeans came to the European continent
Makovka662 [10]

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.

What should you do if you get stuck in a rip current? Why?
Schach [20]

Answer:  Swim parallel to shore to escape the current.

Explanation:

Most rip currents are between 30 and 100 feet (9.1 and 30.5 m) wide. Look for the nearest breaking waves; they indicate the current's edge. Swim toward the waves, and be sure to move parallel to the shore instead of directly towards it.
