All Flashcards
Define Geographic Data.
Information linked to specific locations on Earth, including coordinates, place names, terrain features, land use patterns, and population statistics.
What are Terrain Features?
Physical characteristics of the Earth's surface, such as mountains, valleys, rivers, lakes, and oceans.
What is meant by Land Use Patterns?
How land is used in a specific area, categorized as agricultural, residential, commercial, industrial, or natural.
Define Population Density.
The number of people per unit area.
Define Remote Sensing.
Using satellite or aerial imagery to collect data about the Earth's surface.
What is GIS?
A computer system for mapping and analyzing spatial data using layers.
Define GPS.
A system using satellites to determine precise locations on Earth.
Define Age Structure.
The distribution of a population by age groups.
Define Gender Ratio.
The proportion of males to females in a population.
Define Life Expectancy.
The average lifespan of individuals in a population.
What are the causes and effects of rapid urban growth?
Causes: migration, economic opportunities. Effects: increased traffic, air pollution, strain on infrastructure.
What are the causes and effects of deforestation?
Causes: agriculture, logging. Effects: habitat loss, soil erosion, climate change.
What are the causes and effects of urban sprawl?
Causes: population growth, car dependency. Effects: increased commuting, loss of farmland, environmental degradation.
What are the causes and effects of air pollution?
Causes: industrial emissions, vehicle exhaust. Effects: respiratory problems, climate change, acid rain.
What are the causes and effects of migration?
Causes: economic opportunities, political instability. Effects: population shifts, cultural diffusion, economic changes.
What are the causes and effects of high population density?
Causes: urbanization, economic opportunities. Effects: strain on resources, increased competition, innovation.
What are the causes and effects of an aging population?
Causes: increased life expectancy, decreased birth rates. Effects: increased healthcare costs, labor shortages, economic challenges.
What are the causes and effects of natural resource depletion?
Causes: overconsumption, unsustainable practices. Effects: environmental degradation, resource scarcity, economic instability.
What are the causes and effects of climate change?
Causes: greenhouse gas emissions, deforestation. Effects: rising temperatures, sea level rise, extreme weather events.
What are the causes and effects of soil erosion?
Causes: deforestation, overgrazing. Effects: loss of fertile land, reduced agricultural productivity, water pollution.
Compare GPS, GIS, and Remote Sensing.
GPS: location tracking. GIS: spatial analysis using layers. Remote Sensing: data collection via satellite/aerial imagery.
Compare agricultural, residential, commercial, and industrial land use.
Agricultural: farming. Residential: housing. Commercial: businesses. Industrial: manufacturing.
Compare population density and population distribution.
Population density: people per unit area. Population distribution: how people are spread across an area.
Compare birth rate and death rate.
Birth rate: births per 1,000 people. Death rate: deaths per 1,000 people.
Compare mountains and valleys.
Mountains: high elevation. Valleys: low areas between mountains or hills.
Compare rivers and lakes.
Rivers: flowing waterways. Lakes: bodies of water surrounded by land.
Compare urban and rural areas.
Urban: high population density, built environment. Rural: low population density, natural environment.
Compare satellite and aerial imagery in remote sensing.
Satellite imagery: broad coverage, continuous monitoring. Aerial imagery: high resolution, localized data.
Compare total population and population growth rate.
Total population: number of people. Population growth rate: rate at which the population is increasing.
Compare the uses of GIS in urban planning and environmental management.
Urban planning: land use, transportation. Environmental management: resource monitoring, pollution control.
