relative location

  • Describes a place’s position in relation to other places.

  • More subjective way of pinpointing a location, often used in everyday conversations and directions.

11
New cards

absolute location

The exact location of a place on Earth, usually expressed as latitude and longitude coordinates.

18
New cards

How do geographers use Census Bureau data?

  • Analyze population demographics, housing trends, economic indicators, and social characteristics.

  • Collect data on population density, age distribution, income levels, education attainment, employment rates, and housing types.

  • Identify urban growth patterns, demographic shifts, and socioeconomic disparities.

19
New cards

How do geographers use remote sensing data?

  • Monitor land use changes, natural disasters, and environmental impacts.

  • Examine land cover, vegetation health, water bodies, urban expansion, and deforestation.

  • Track urban sprawl, identifying deforestation hotspots, and assessing the impact of climate change.

20
New cards

Significance of GPS in geography.

Global Positioning System

  • Provides accuratelatitude, longitude, and altitude data, essential for mapping, navigation, and GIS.

  • Enables real-time tracking of objects and people, useful for wildlife tracking, emergency response, and logistics.

  • GPS data integrated with GIS allows for analyzing spatial patterns and relationships, aiding in understanding geographic phenomena like urban growth and climate change impacts.

21
New cards

Significance of GIS in geography.

Geographic Information System

  • Allows geographers to analyze spatial patterns, relationships, and trends.

  • Enables the creation of maps and visualizations that communicate complex spatial information effectively.

22

27
New cards

When to use Robinson Projection.

  • Produces a visually pleasing map of the entire world.

  • Minimizes distortion in area, shape, distance, and direction, making it suitable for general reference.

31
New cards

When to use Lambert Conformal Conic Projection.

  • Accurately represents the shapes of features, especially within the standard parallels.

  • Minimizes distortion in area and distance, particularly near the standard parallels.

  • Popular projection for topographic maps, nautical charts, and large-scale maps of countries like the United States.

32
New cards

When to use Peters Projection.

  • Provides a more accurate depiction of the relative size of countries, particularly those in the Global South.

  • Challenges the traditional Eurocentric view of the world, which often exaggerates the size of European and North American countries.

  • Used to highlight global inequalities and promote a more balanced perspective on world affairs.

33
New cards

remote sensing

  • Any method of collecting data about an object or location without making physical contact with it.

  • Main purpose is to determine information about an object or phenomenon that can’t be assessed through physical contact or that requires additional research.

New cards

How does a sun-synchronous orbit work?

It is an orbit a satellite takes around the Earth where the movement and orbit of the satellite always appear the same from the perspective of the Sun.

36
New cards

What are geostationary orbitsand what are they used for?

  • Orbits undergone by satellites in which the satellite orbits directly over the Earth’s equator and completes a single orbital period at the same rate the Earth rotates.

  • This amounts to the satellite remaining in the same position in the sky throughout the whole day.

48
New cards

How are ecosystems, habitat, and niche related?

  • Ecosystems are the dynamic interaction between the biotic(living) and abiotic(nonliving) factors in a geographic area.

  • The habitat is a place suitable for a particular organism to live.

  • The niche of an organism is the unique and specific role it plays in its ecosystem.

60
New cards

primary succession

An example is the recovery of an ecosystem after lava covers the ground or a glacier retreats.

61
New cards

secondary succession

An example would be the recovery of a forest after a forest fire. Grasses, followed by shrubs and a variety of tree species, would eventually grow after some time.

62
New cards

What influences where people live?

  • Living by flood plains(rivers) for agriculture.
