GED Social Studies: Civilizations, Environment, and Society Concepts
Importance ★★★★★ · 40% (estimate)
Overview
This chapter looks at how geography shaped early societies and how people use and change the environment.
Early civilizations, such as Egypt along the Nile and Mesopotamia between the Tigris and Euphrates, grew near rivers that gave water, rich soil, and transportation. Classical Athens developed an early direct democracy, and the Roman Republic offered a model of representative government.
People depend on natural resources. Renewable resources, such as wind and sunlight, are replaced naturally, while fossil fuels are not. Technology lets people change the environment, for example by building dams or clearing forests, with both benefits and costs. Sustainability means meeting today's needs without harming future generations' ability to meet theirs.
Key concepts
River civilizations
Early civilizations grew along rivers for water, fertile soil, and transportation.
Memory tipNile = Egypt; Tigris and Euphrates = Mesopotamia.
Classical civilizations
Athens: early direct democracy. Roman Republic: elected representatives.
Memory tipAthens direct, Rome representative.
Renewable vs. nonrenewable
Renewable resources are replaced naturally (wind, sun). Nonrenewable ones take millions of years (coal, oil, gas).
Memory tipFossil fuels are nonrenewable.
Sustainability
Using resources so that future generations can still meet their needs.
Memory tipReplant, conserve, reuse.
Human changes
People alter the environment by building dams, roads, and farms, or by cutting forests.
Memory tipVolcanoes are natural, not human changes.
Often tested
- Deforestation causes habitat loss and soil erosion.
- Most human changes to the environment have both benefits and costs.
3 sample questions
Verified practice questions from this unit.
Question 1. Many early civilizations, such as ancient Egypt and Mesopotamia, grew up near what kind of place?
- ① Mountain tops
- ② Deserts far from water
- ③ Frozen polar regions
- ④ Rivers
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ Rivers
Key point: Early civilizations grew along rivers
Rivers provided water for drinking and crops, rich soil from floods, and a way to travel and trade. Ancient Egypt grew along the Nile, and Mesopotamia grew between the Tigris and Euphrates rivers.
Wrong choices
- Mountain tops: Mountain tops are hard to farm and travel to.
- Deserts far from water: Deserts far from water could not support large farming communities.
- Frozen polar regions: Polar regions are too cold for farming.
Question 2. Which of these is a renewable resource?
- ① Coal
- ② Oil
- ③ Natural gas
- ④ Wind
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ Wind
Key point: Renewable resources are replaced naturally
A renewable resource is replaced by nature in a short time, such as wind, sunlight, and flowing water. Fossil fuels such as coal, oil, and natural gas are nonrenewable because they take millions of years to form.
Wrong choices
- Coal: Coal takes millions of years to form, so it is nonrenewable.
- Oil: Oil is a fossil fuel, so it is nonrenewable.
- Natural gas: Natural gas is a fossil fuel, so it is nonrenewable.
Question 3. What does sustainability mean?
- ① Never using any natural resources
- ② Buying only goods made in other countries
- ③ Using resources to meet today's needs without harming the ability of future generations to meet their needs
- ④ Using as many resources as possible right now
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ Using resources to meet today's needs without harming the ability of future generations to meet their needs
Key point: Sustainability: meet today's needs, protect tomorrow's
Sustainability means using resources in a way that can continue over time. Examples include replanting trees after logging, conserving water, and using renewable energy.
Wrong choices
- Never using any natural resources: Sustainability allows using resources, as long as they are used wisely.
- Buying only goods made in other countries: Where goods are made is not what sustainability means.
- Using as many resources as possible right now: Using up resources quickly leaves less for the future, which is the opposite of sustainability.
