Part 2 — Answer key

Compare your answers after you have finished Part 1.

1. On a standard world map, which named line marks 0 degrees latitude?
   Equator
2. Lines of longitude meet at the poles and are farthest apart at the equator.
   True
3. A ship is located at 10° N, 20° W. It sails due east across 21 degrees of longitude. At which longitude will it arrive?
   1° E
4. You observe a deep ocean trench running parallel to a coastal mountain range that has many volcanoes. Which plate boundary type most likely explains this pattern?
   Convergent boundary between oceanic and continental plates
5. At the mouth of a large river, sediment has built up into a roughly triangular landform that juts into the sea and splits the river into several channels. What is this landform called?
   Delta
6. An isthmus is a narrow strip of land that connects two larger land areas and separates two bodies of water.
   True
7. While analyzing a country for a geographytest10 population study, you see a population pyramid with a very wide base and a narrow top. Which challenge is this country most likely to face in the next two decades?
   High demand for schools and entry-level jobs
8. Two cities are located at the same latitude, but City A is on the west coast beside a large ocean, and City B is far inland. City A has milder winters and cooler summers. What physical factor best explains this difference?
   Prevailing winds blowing offshore in summer
9. The Coriolis effect causes winds to be deflected to the left in the Northern Hemisphere and to the right in the Southern Hemisphere.
   False
10. You are designing a choropleth map of population density for a geographytest10-style assessment. Which cartographic practices help readers interpret the map accurately? Select all that apply.
    Choosing class breaks that match meaningful thresholds in the data; Labeling the map with a concise, descriptive title; Including a clear legend that explains the color ramp
11. A tectonic plate boundary shows frequent shallow earthquakes, a long linear rift on land, and a mid-ocean ridge offshore. Which features are typically associated with this type of boundary? Select all that apply.
    Generation of new oceanic crust; Mid-ocean ridges with volcanic activity; Rift valleys on land
12. Arrange these stages in the journey of a large river from its upland source to its coastal mouth, in the most typical sequence.
    Correct order: Steep headwater streams in uplands → Widening valley with meanders → Broad floodplain with natural levees → Distributary channels forming a delta
13. A flight planner is choosing a near great-circle route for a passenger jet traveling from New York to Tokyo. Over which general region will this route most likely pass?
    Arctic region near Alaska
14. A country has one very large primate city that dominates its economy and politics. Which underlying factor most likely contributed to this urban pattern?
    Highly centralized political and economic power
15. A government wants to reduce congestion and overpopulation pressures in its primate city. Which policies are most likely to encourage counter-urbanization toward smaller cities and towns? Select all that apply.
    Subsidizing high-speed internet in rural towns; Offering tax breaks to firms that open offices in mid-sized cities; Relocating some national ministries to secondary cities
16. You are classifying climates for a geography-test-10 project. A region lies on the leeward side of a high mountain range in the subtropics, has very low annual precipitation, large daily temperature ranges, and cool winters due to elevation. Which climate type best fits this description?
    Cold desert climate
17. A coastal city at 45° N on the west coast of a continent has mild, wet winters and cool summers, influenced by a warm ocean current. Which factors help explain this climate pattern? Select all that apply.
    Location at a relatively high latitude; Prevailing westerly winds blowing from the ocean to land; Strong maritime influence from a nearby ocean
