All terms in this list:
collaborate: to work together reach a goal
oceanography: a branch of science that studies the earth's oceans
topographic map: detailed map showing the hills and valleys of an area by using contour lines to represent changes in elevation
experimental error: errors caused by inconsistencies and inaccuracies while collecting experimental data that can be limited by repeating the experiment many times
geothermal energy: an alternative form of renewable energy harnessed from underground reservoirs of steam and hot water located on a plate boundary where continental plate movements cause rifting or mountain formation
contour lines: lines on a topographic map connecting points of equal elevation
index contours: contour lines on a topographic map that are market with their corresponding elevation
scientific law: a basic principle that describes the behavior of a natural phenomenon, often thought of as a “rule of nature”, even though the cause of the law many not be known.
earth science: a branch of science that studies the interaction of earth’s land, water, air and outer space
hemisphere: half of the earth
continent: one of the seven major land areas of the earth
equator: the line of 0o latitude halfway between the poles separating the northern hemisphere from the southem hemisphere
aqueduct: a system of man-made canals, tunnels, and pipelines built to transport fresh water into highly populated areas where there is not enough
hypothesis: a specific, testable proposed answer to one scientific question
astronomy: a branch of science that studies outer space and the objects in it
plateau: a relatively flat elevated area of land that rises above the surrounding landscape
contour interval: the difference in elevation between two side-by-side contour lines
geology: a branch of science that studies the solid parts of the earth and how natural forces change our planet
meteorology: a branch of science that studies the earth’s atmosphere and weather
blind study: experiments in which the scientists do not know which group is the control group and which group is the test group that are designed to limit observer’s bias
limestone: an industrial mineral use to make a cement which forms from the shells and skeletons of marine organism
placer: an accumulation of dense minerals found in sand and gravel in modern or ancient stream beds formed by the geologic processes of transport and deposition
observers bias: tendencies influenced by what an experiment expects to see that result in experimental errors
topographic profile: a cross-sectional view along a line draw on a topographic map showing the shape of the surface of the ground including hills, mountains, cliffs, valleys, rivers and lakes
scientific theory: an explanation based on many observations during repeated scientific experiments: can be changed or modified with the discovery of new data.
