Earth Science

Earth science or geoscience is an all-encompassing term that refers to the fields ofscience dealing with planet Earth.

Geology
the science that deals with the earth’s physical structure and substance, its history, and the processes that act on it.
Oceanology
The branch of earth science that studies the ocean
Meteorology
The scientific study of the atmosphere.
Astronomy
The branch of science that deals with space and physical universe as a whole.
Environmental Science
The branch of science dealing with the physical, chemical, biological conditions.
Scientific Method
a method of research in which a problem is identified, relevant data aregathered, a hypothesis is formulated from these data, and thehypothesis is empirically tested.
Controlled Experiment

 

Experiment where all sujects are treated the exact same.
Control Group
The plain group, used to compare the experimental groups to. By comparing you can measure the change. This is sometimes considered the “normal” group.
Experimental Group
The group that receives the variable being tested. There will be ONE thing that is different in these groups. It will be something that the scientist changes, not something that just happens on its own.
Independent Variable
This is the factor being tested. The scientist chose it and made it different in each group.
Dependent Variable
This “depends” on the independent variable. The independent variable CAUSES it to happen. It is the thing that is measured and recored during and after the experiment. It happens on its own, it is the results.
Topographic Map
A type of map characterized by large-scale detail.
Relief
The amount of change in elevation on the surface of the Earth.
Contour Lines
Line on a topographic map that indicates elevation; Every point along a contour line has the same elevation.
Contour Intervals
On a topographic map, tells the distance in elevation between adjacent contour lines.
Contour Map Rules
Basically a guide to reading topographic maps
Components of a Map
The main things on a map.
Lattitude
Includes the equator which is the line of lattitude at 0 degrees and runs north and south.
Longitude
Includes the Prime Meridian which is the longitude line at 0 degrees. Runs east to west.
Google Docs
Used to write papers or powerpoints on google.
