World In Spatial TermsAbsolute Location
The exact position of a place on the earth’s surface which is determined by grid.
– Patterns formed as the lines of latitude (parallels) and longitude (meridians) cross each other.
Prime Meridian & Equator
• Zero degrees longitude marks the central point separating the eastern and western Hemispheres
• Zero degrees latitude which separate the Northern and Southern Hemisphere and are equal distance to the north and south pole.
Prime Meridian
Equator
Ring of Fire• An arc stretching around the borders of many
of the worlds major plates where 70% of the worlds tectonic activity occurs.
Weathering & Erosion
• Weathering is the decomposition of Earth's rock, and minerals through chemical or physical processes.
• Erosion is the movement of earth by wind, water or glaciation.
• Formal Regions: Defined by one or more common characteristic.
• Perceptual Regions: An area with common feelings or images rather than physical or tangible similarities.
• Functional Region: A central place and the surrounding area linked to it
Regions
• Steppe: Refers to a biome region characterized by grassland plains without trees.
• Tropical Rainforest: An ecosystem often found around the equator characterized by evergreen vegetation and high levels of rain
• Desert: A region characterized with very little vegetation and precipitation
Climate Regions
Solstices
• Winter Solstice: The shortest day of light (December 22)
• Summer Solstice: The longest day of light (June 21)
Communism• Society based on economic equality where
decisions about production & distribution are made by the central authority
• Examples are Cuba and North Korea
Unitary system
• Top down power structure- decisions are made by the central government and then affect the people
• Examples: Oligarchy, Communism
Federal System
• Power comes from the people on the bottom and affects the people on top
• Divides power between the state and federal government
Primary SectorEconomic sector that changes natural
resources into primary products. This sector includes:
Agriculture, Fishing, Forestry, Mining
Secondary Sector
Economic sector that creates a finished, usable product. It uses the output of the primary sector and manufactures finished goods or products.
Tertiary SectorBetter known as the service
sector. Economic sector that provides services to business as well as final consumers.
Quaternary Sector
Economic sector that provides intellectual services like research, development, and information.
Economic Systems1. Command Economy – economic system in which economic
decisions about production & distribution are made by the central authority
2. Market Economy – an economic system based on free enterprise, in which businesses are privately owned, and production & prices are determined by supply & demand.
3. Traditional Economy – a system in which tradition and custom control all economic activity; exists in only a few parts of the world today dominated by methods and techniques that have strong social support even though they may be old-fashioned or out of date
Trade Routes/ Groups1. Triangle Trade – colonial trade route between New England,
the West Indies, and Africa.
2. Silk Road – early trade route stretching from China to the Mediterranean.
3. CAFTA (Central American Free Trade Agreement) – trade agreement made by the U.S. & the Central American countries of Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua.
4. NAFTA (North American Free Trade Agreement) – trade agreement made in 1994 by Canada, the U.S. and Mexico
1st Agricultural Revolutionaka Neolithic Revolution
Period which marked a transition from Hunting and Gathering to Agriculture and Settlement
2nd Agricultural Revolution• Innovations in farm machinery made
farming easier and increased food production.
• greatly contributed to the industrial revolution.
Industrial Revolution• Economic change in which many of the
world’s nations experienced rapid transformations into Industrial economies from agricultural economies
Green Revolution
• A increase in agricultural productivity resulting due to the introduction of high-yield varieties of grains, the use of pesticides, and improved management techniques.
Subsistence Agriculture
• Type of farming that produces just enough
food for a family or village to survive.
Commercial Agriculture• Type of farming where crops are produced on
a large scale to feed huge populations for profit by corporations
Shifting Cultivation• Farmers use the land until all of the soil’s
nutrients are used up. Then they move to another location and repeat the process.
Crop Rotation
• planting of different crops on the same land to improve soil fertility and help control insects
and diseases.
Sustainable development
• Development without depleting natural resources
• Depleting- using up
Three Gorges Dam• world's largest electricity-generating plant • project sets records for number of people
displaced (more than 1.2 million), number of cities and towns flooded (13 cities, 140 towns, 1,350 villages).
• Located in China
Aswan Dam• Located in Egypt• regulate river flooding, to provide storage of
water for agriculture, and to generate electricity
Panama Canal
• Connects the Atlantic and Pacific ocean. Shortens the distance goods travel between Asia and Europe
