Maps
What is a cartographer?
A person who creates maps
What are longitude lines?
Semi-circle lines between the poles on a globe. The highest possible reading is 180 degrees.
What is the main thing that causes Earth's seasons?
The global tilt.
What is the thinnest layer of the Earth?
The crust
What property makes a resource precious or valuable?
The need, demand, and accessibility of that resource.
What are the three main ways GIS data is collected?
Surveying - using instruments on land to determine distance between points.
Remote sensing - satellites or aircraft-mounted instruments that can rapidly and accurately map large areas of earth.
Acoustic/sonar sensing - using sound waves to map the bottoms of the oceans.
What are latitude lines?
The circles on a globe, parallel to the equator.
What would happen if the Earth orbited the sun beyond the habitability zone?
Too little sunlight for plants to grow, too cold for life, carbon dioxide clouds, no liquid water (it would turn to ice)
What is the Moho?
The boundary between the crust and the mantle.
What is a natural resource?
a raw material that we use from our enviroment.
What are the four main types of maps we learned about in class?
Geographic - focuses on names, symbols, & locations (roads, streams, oceans)
Political - shows names, boundaries, and shapes of countries
Topographic - displays elevation and landform information, usually by contour lines or shading
Thematic - a theme us used to make a map, such as the location of clean water vs. contaminated water
What is the International Date Line?
A line that roughly follows the 180 degree meridian in the western Pacific Ocean where each new day begins at midnight.
What is the resource on earth that no other planet has and is essential for life?
liquid water
What do scientists believe probably makes up the majority of the earth's core?
iron
What is a renewable resource?
resources that have an unlimited supply or are easily replenished.
What are the types of map projections we learned about in class?
Polar - when the projection touches one of the poles.
Oblique - When the projection touches anything between the poles and the equator
Equatorial - When the projection touches the equator.
What are the tropic of Cancer and Tropic of Capricorn?
Tropic of Cancer - latitude 23.5 degrees north
Tropic of Capricorn - latitude 23.5 degrees south
The area between them makes up the tropics. About 1/3 of earth's population lives in this region because of the desirable climate.
What are some ways we can get the most out of nonrenewable resources?
Recycle, reuse, find alternative sources
What is the term for the study of the Earth?
Geology
What is a nonrenewable resource?
Natural resources than cannot be replenished after they are used.
What is a map?
A simplified image that models part of the earth.
What is GIS?
Geographic Information System. Different layers of information can be shown to show different data within a map.
What are cardinal directions?
North, south, east, west
What are the layers of the earth, beginning on the surface?
1. Crust - outermost layer, thinest, oceanic & continental
2. Lithosphere - tectonic plates
3. Upper Mantle
4. Asthenosphere
5. Lower mantle
6. outer core - liquid iron
7. inner core - solid iron
What is the difference between biological resources and nonbiological resources?
Biological - resources resources that are living (fish, lumber)
Nonbiological - resources that are not alive (iron ore, water, soil)
