100
which way do latitude lines run?
AND
which way do longitude lines run?
horizontal
OR
north to south
AND
west to east
OR
vertical
100
equal to your latitude
What is Polaris
100
use your four senses for this
What is an Observation
200
what unit it is measured in
g/cm3
200
Indirect/Inverse vs. Direct vs. Cyclic
Indirect/Inverse: x gets bigger, y gets smaller
Direct: x gets bigger, y gets bigger
Cyclic: repeating pattern, predictable
200
prime meridian for ????
equator for ????
Equator- 0° Latitude
Prime Meridian-0° Longitude
200
what is Altitude?
height above sea level
Sea level= 0°
200
a conclusion or prediction based on observations
What is an Inference
300
what is it?
(Density^)
the amount of matter in a specific volume
300
the shape of Earth
What is an oblate spheroid
^slightly bulging at the equator
300
What star equals latitude in the NH?
What is Polaris
300
based on your longitude
What is solar time
300
Difference between Observations and Inferences
Observations- facts
- repeatable/seen by many
- 5 senses
- made better by technology
Inferences-predictions
-may or may not be correct
-good ones connect observations
- must be changed if it doesn't agree with and
observation
400
the tendency for and object to float in a liquid
What is buoyancy
400
what is some evidence of Earth's shape?
1) Photographs from outer space show that Earth is round
AND/OR
2) Ships slowly disappear/ appear over the horizon
AND/OR
3)Gravity measurements
400
MINUTES and SECONDS??
When a more precise description of lat. and long. are needed
Minutes-( ' )
Seconds-( " )
400
where is the North Star,(Polaris), not visible?
Southern Hemisphere
400
Metric prefixes makes units larger or smaller by a factor of 10
What are Metric Conversions
500
the only wayS to change the density of an object
1.To heat or cool an object because that only changes the volume not the mass.
2. To squeeze the object (pressure)
500
Why are there different layers of Earth and other planets?
AND
What ESRT page would one find the layers and inferred properties of Earth's interior?
different densities
AND
ESRT pg. 10
500
TIME ZONES??!!??
same time is used throughout a zone,(instead of local time)
Since Earth rotates 15° per hour, each time zone is spaced at 15°, and each time zone (+) or (-) either left to right.
500
as your latitude increases, Polaris' altitude _______
increases
500
used to find the volume of small objects
What is a graduated cylinder (Water Displacement Method)
