The correct answer is:
- It created land bridges where ocean had once been.
- It required people to create new shelters.
- It required people to form larger communities.
- It required people to live closer together.
During the last ice age, large portions of the Earth's water supply were frozen, causing sea levels to lower. This exposed land bridges in some areas, such as the Bering land bridge between Siberia and Alaska. This created new migration routes for humans and allowed for the spread of populations to new regions.
As the climate became colder, humans had to adapt by creating new types of shelters to protect themselves from the harsh conditions, such as caves, huts, and underground dwellings.
The need for survival and cooperation likely led to the formation of larger communities, as individuals could work together to hunt, gather resources, and provide mutual protection.
The scarcity of resources during the last ice age likely necessitated people to live closer together, increasing competition for resources and making it more beneficial to live in close proximity to others.
The last ice age had significant effects on human migration. Here's a step-by-step breakdown of those effects:
1. It created land bridges where ocean had once been: During the ice age, large amounts of water were locked up in ice sheets, causing the sea levels to drop. This exposed land bridges, such as the Bering Land Bridge, which connected Asia and North America. This allowed human migration and the movement of animals across these land bridges.
2. It required people to create new shelters: As the climate changed and temperatures dropped during the ice age, humans had to adapt to colder conditions by creating new types of shelters. They needed to find ways to insulate themselves from the cold and protect themselves from harsh weather conditions.
3. It required people to form larger communities: In order to survive and thrive in the unforgiving ice age environment, humans had to come together and form larger communities. This allowed for better resource sharing, increased efficiency in hunting and gathering, and enhanced protection against predators.
4. It required people to live closer together: With the decrease in habitable areas due to expanding ice sheets, humans had to live in closer proximity to each other. This led to increased social interactions and exchanges of knowledge and resources within communities.
Overall, the last ice age forced humans to adapt and evolve in various ways, including migration across land bridges, the development of new shelter types, the formation of larger communities, and living in closer proximity to one another.
