A group of disciplines that have a common approach to improving our understanding of how nature works.
Name the order of the scientific method
Make observations on some aspect of the universe
Make an "educated guess" to explain the observations
Use the hypothesis to predict other aspects of the nature of the universe.
Test the predictions by experiments and/or further observations.
If the predictions are not supported, use the experimental results and/or new observations to modify the hypothesis and then repeat steps 3 and 4.
When all the predictions are supported by the experiments and/or new observations the hypothesis becomes a theory. A theory is a conceptual framework that explains exisiting observations and predicts new ones.
Statistical techniques that provide a means of testing predictions.
Quantitive methods
______ _______ are not accepted based on the presitge, convincing powers or charisma of the proponent, but on the results obtained through observations and/or experiments which are reproducible.
Scientific findings
A statistical procedure to test whether two samples have a statisticly similar or dissimilar average value.
Mann-Whitney U test
There is no significant difference in the average temperatures of the two samples. Null Hypothesis.
Name the three natural refrence points
The north and south poles,
Where the axis of rotation intersects the surface,
and the Equator
An imaginary circle around the Earth lying midway between the poles.
North-south lines
Meridians (longitude)
East-West lines
Parallels (latitude)
Coordinates on a map that represent the intersection of a line of latitude and a line of longitude and indicates the ________ _______.
absolute location
The angular distance of a point measured either north or south from the equator
Parallels of latitude are constructed by means of _______ _________ ______ ___ ______ ___ ____ _______.
angular measurement from the center of the Earth.
Lines that run North and South from pole to pole, and measure distance in degrees to the East and West of the Prime Meridian.
Passes through Greenwich,England, and is designated 0 degrees longitude.
Prime Meridian
The shape of the land
usually average sea level
the datum
The mean (average) sea level as of 1929
National Geodetic Vertical datum of 1929
Which direction does a contour line point when crossing a stream?
Upstream (uphill)
The change in elevation between two adjacent contour lines
contour interval
The greater the contour interval, the more ______ the terrain
The steeper the slope, the _______ _______ the contour lines. The flatter the land, the ________ ________ the lines are.
closer together/ father apart
Indicates a known elevation point
benck mark, BM682x/ spot height, 5381x
Lines on a topographic map that are shown in brown, and show the height of the land
contour line
Perpetually migrates over the Earth's surface between 23.5 N and 23.5 S.
Vertical sun ray
Regardless of where the Earth is in its orbit, the position of the axis is always parallel to future and past positions.
parallelism of axis
23.5 degrees from a line perpendicular to the plane of orbit.
tilt of the axis
The curious figure 8-shaped object that normally appears on globes just west of South America in the Pacific ocean.
Why does the vertical sun ray migrate over the Earth's surface?
- The tilt of the axis
- The revolution of the Earth
- The parallelism of the axis during rotation
Sunlight or radiant energy from the sun.
The reflectivity of a material.
Solar energy that is absorbed. Will heat up materials.
A measure of the intensity of solar radiation.
A rate of energy production equal to 0.239 cal/sec.
Rate of change of some variable through space or time.
Lines (like contours) that connect points having the same temperature
Name 2 atmospheric and locational factors that might affect the amount of solar radiation reaching a service weather station.
- Cloud coverage
- Greenhouse gases
System of symoblic notation for summarizing weather information from a particular place.
Station model
An instrument for measuring temperature.
An instrument for measuring atmospheric pressure
An instrument for measuring wind speed.
An instrument for measuring atmospheric humidity
Lines connecting points of equal barometric pressure on a weather map.
Lines connecting points of equal temperature on a weather map
Temperature at whcih the air is saturated with moisture.
Dew point temperature
A measure of speed.
Name the three important uses of the weather model
- Demonstrates basic weather frontal structures and airmasses.
- Relates precipitation, wind direction, cloud types, temperatures, and pressures to warm and cold fronts.
- Provides a means of predicting weather conditions.
The result of weather elements interacting over a long time.
Based on mean annual and monthly temperatures and precipitation.
