The Global Grid
What is the Prime Meridian?
Because this is permanent relative to Earth's orbit, the angle of direct sunlight shifts throughout the year, causing seasons.
What is Earth’s tilt?
Using the wardrobe analogy, one represents the outfit you choose to wear today, while the other represents the entire wardrobe you own.
What are Weather and Climate?
Once consumed, these materials—including minerals and fossil fuels—cannot be replaced.
What are Nonrenewable Resources?
These are negative reasons, such as war or persecution, that force people to leave their home country.
What are Push Factors?
This term describes the exact point where a specific line of latitude intersects with a specific line of longitude.
What is Absolute Location?
This process involves the physical removal and movement of rock pieces by water, ice, and wind.
What is Erosion?
These low-latitude regions near the equator are consistently hot because the sun is overhead nearly all year long.
What are the Tropics?
This is the mass movement of people from rural areas to cities, primarily driven by the search for jobs.
What is Urbanization?
These are positive reasons, such as better living conditions or jobs, that attract people to a new country.
What are Pull Factors?
This layer of hot rock directly beneath the crust is unique because it flows like melted plastic.
This term describes an unintended environmental impact, like air pollution, that affects people not involved in the activity that caused it.
What is a Spillover?
What are Birth Rates and Death Rates?
While one uses a satellite network for navigation, the other is a computer-based system used for layering data for complex analysis.
What are GPS and GIS?
This tectonic mechanism occurs when two plates push against each other, causing the crust to bend and fold upward.
What is the formation of Fold Mountains?
These act as thermal regulators because water takes much longer to heat up and cool down than land.
What are Oceans?
These represent the two ways humans use land: either by following natural features or by actively altering them, such as clearing wetlands for malls.
What are Adaptation and Transformation?
These terms distinguish between the act of leaving one's home country and the act of entering a new destination country.
What are Emigrate and Immigrate?
To ensure mathematical precision, degrees in the grid system are divided into 60 of these, which are further divided into seconds.
What are Minutes?
This process, where oceanic crust is forced beneath continental crust, creates the magma and volcanoes found in the Ring of Fire.
What is Subduction?
This three-stage cycle of Evaporation, Condensation, and Precipitation is the process by which Earth recycles its water.
What is the Water Cycle?
This widespread clearing of forests destroys natural habitats and reduces biodiversity, the variety of living things in an ecosystem.
What is Deforestation?
What is Movement?
