Look at the map. Which ecosystems show where early civilizations developed because the area allowed people to grow crops even during times with little rainfall? Select all that apply.

Answer 1

To accurately answer your question, I would need to look at the specific map you are referencing. However, I can provide some general information about ecosystems that are known to have supported early civilizations due to their agricultural potential, especially in areas with limited rainfall.

1. River Valleys: Many early civilizations developed in fertile river valleys like the Nile (Egypt), Tigris and Euphrates (Mesopotamia), and Indus River (India). These areas typically allowed for irrigation, which supported agriculture even during drier periods.

2. Coastal Plains: Regions along coasts where sediment deposits create fertile soil often supported agriculture.

3. Savannas: In some regions, the savanna ecosystem provided opportunities for agriculture, especially with the development of irrigation techniques to cope with dry seasons.

4. Floodplains: Areas that are periodically flooded can enrich the soil, making them suitable for farming even with fluctuating rainfall patterns.

If your map highlights areas like these, they are likely to be locations where early civilizations developed due to their agricultural advantages.
