Question | Answer |
Subfields of Geography? | Hydrosphere (bodies of water) and Lithosphere (The ground. I.e.: hills, valleys, mountains) |
Where does latitude begin? | 0 (N-S) to 90 *Equator* |
Where does longitude begin? | 0-180 (E-W) *Greenwich, England* |
Coordinates of Capricorn | 23.5 SOUTH |
Coordinates of Cancer | 23.5 NORTH |
Coordinates of Equator | 0 LATITUDE, ANY longitude |
Coordinates of Arctic Circle | 66.5 NORTH |
Coordinates of Antarctic Circle | 66.5 SOUTH |
Coordinates of Prime Meridian | 0- LONGITUDE, ANY Latitude |
Coordinates of Mobile Alabama | 30.70 North |
Maximum Measurement of Latitude? | 90 Degrees North or South of Equator |
Maximum Measurement of Longitude? | 180 Degrees East or West of Prime Meridian |
Shape of the Earth? | Oblate Spheroid (Bulge at equator, flattened poles) |
Four Types of Map Distortions? | Area, Shape, Distance, Direction |
Three families of projections? | Plane (Azimuthal), Cylindrical, Conic |
What is Plane Projection best for? | POLAR AREA |
What is Cylindrical projection best for? | WORLD MAP *SAILORS*** |
What is Conic projection best for? | U.S. / Wide East-West Maps |
What is the problem with the Mercator projection? | Distorts size of objects as latitude increases |
What is GIS? | Geographic Information Systems (Complex computer program that puts lots of maps together to study data) |
What is remote sensing? | Drones/ Satellites... Mechanical collection of data from a distance, often aerial |
What are isolines? | Lines drawn to join equal points |
What are contour lines | Connect two points of equal elevation |
What is the purpose of topographic maps? | To contour equal lines of elevation (physical geography) *Has vertical scale to determine a point in a 3 dimensional space* |
What is a mineral? | Naturally occurring, inorganic substance |
What four minerals comprise most of the Earth? | silicate, oxygen, iron, magnesium |
What are the two most abundant minerals on Earth? | Oxygen and silicate |
What is a rock? | Inorganic substance containing one or more minerals |
What are the three rock types? | Igneous (NEW ROCK), sedimentary (SEDIMENT), magnesium (CHANGED ROCK) |
Extrusive rock? | Igneous rock formed above ground. Cools quickly, no visible crystals |
Intrusive rock? | Below ground, cools slowly, large crystals |
What forms sedimentary rock? | Sediment deposited by wind, water, ice cemented together into rock |
What forms limestone? | Mostly skeletal material of marine organisms (shells, coral etc) |
What type of rock forms on lake bottoms and ocean floors? | Sedimentary |
How is metamorphic rock formed? | CHANGED ROCK.... Formed by other rocks under intense heat and pressure |
Which rock type is easiest to erode? | Sedimentary |
2 examples of sedimentary rock? | Limestone and Sandstone |
2 examples of Igneous rock? | Basalt and granite |
2 examples of metamorphic rock? | Quartzite and marble |
What rock type is found continentally? | Igneous |
What rock types are found oceanicly? | Sedimentary and Igneous |
How have scientists learned about the Earth's interior? | Seismic waves (earthquakes) |
Three types of seismic waves? | PRIMARY, SECONDARY, SURFACE |
Describe Primary Waves: | Travel fastest, travel through any material |
Describe Secondary Waves: | Slower waves, travel only through solids |
Describe Surface Waves: | Slowest waves, CAUSE MOST DAMAGE |
Surface Waves can be compared to... | waves in the Ocean |
Which Seismic waves can travel through liquid? | Primary Waves |
Earth's layers in order from inner most: | Inner Core (solid), Outer Core (Liquid), Mantle (Plastic-like), Crust (solid) |
Inner Core material: | Solid |
Outer core material: | Liquid |
Mantle material: | Plastic Like |
Crust Material: | Solid |
Oceanic VS Continental Crust: | Oceanic Crust: THINNER, YOUNGER, HEAVIER Continental Crust: OLDER, THICKER, LIGHTER |
How old is Earth, as per radiometric dating? | 4.5 Billion years old |
Describe the theory of catastrophism? | Explains why landforms are shaped the way they are. Blames catastrophes not operating today. |
Describe the theory of uniformitarianism? | Present is key to the past. Laws govern landscape processes. *What we use today* |
Evidence supporting continental drift theory? | Shapes/biological/geological matching |
What is Pangea? | "New Earth" (All continents were once one) |
Who is Alfred Wegener? | Biogeographer who proposed continental drift theory |
What evidence supports sea floor spreading? | Used to explain plate motion (lithosphere) |
What are the components of the plate tectonics theory? | Continental drift + seafloor spreading + new data. Plate process of formation/movement/ deconstruction Answers why volcanoes/earthquakes happen where they do |
How are convection and plate tectonics theory connected? | Mechanism is convection (transfer of heat/energy) |
Longitude Measures What directions? | East/West |
Latitude Measures what directions? | North/South |
Circles of illumination? | Divides the Earth into two equal halves: one is illuminated by the sun, one is dark |
Define Parallels | Straight lines that never converge, EQUALLY SPACED |
Define meridians | Converge at the poles |
Science of map making is called | Cartography |
Definition of Map | Generalized view of an area as seen from above and reduced in size |
Advantages of globe: | True shapes, directions and areas (On map, one or more of these is lost when trying to accurately flatten a sphere) |
Lines of longitude are called... | Meridians |
180 degrees East and West meet at... | The international date line |
Longitude uses | Passage of the day and seconds/minutes |
One degree of latitude is equal to about... | 69 miles/ 60 minutes Each degree can be broken down to minutes and seconds |
Relative location | Descriptive |
Absolute location | Mathematically based |
Graticule | Pattern of parallel and medians on a globe |
New theory for motion (1930s) | Thermal connective cells in the upper mantle, like boiling water |
Paleomagnetism | Reversal of Earths magnetic field |
