Which data type uses numbers you can measure?
quantitative data
What is GIS?
Geographic Information System--tool that stores, analyzes, and displays geographic data in layer using digital maps
What is fieldwork?
Going outside to observe and measure things
What is the first step in the scientific method?
Asking a question (an enquiry question)
What is the starting point for measuring longitude (located in Greenwich, England)?
the prime meridian
What kind of information is collected through words, descriptions, or opinions?
qualitative data
Is GIS only useful for scientists? Why or why not?
No, we the public use GIS everyday
What is a hypothesis?
A prediction geographers make that can be tested with data.

Neither-- both are important
What is the name of the imaginary lines that run from the North Pole to the South Pole and measure distances east or west?
longitude
What is primary data?
Data you collect yourself in real time, like recording temperatures outside your school.
GIS is helpful in spotting these, which are difficult to see in raw numbers.

-draw conclusions from the data
-evaluate your enquiry
What are coordinates?
A set of numbers using latitude and longitude that tells you exactly where you are on a map
