contour line a line that shows elevation on a map elevation the height above sea level of a point on Earth's surface Equator half way between North and South Poles, imaginary line that circles the Earth globe is a sphere that represents Earth's entire surface hemisphere is one half of the sphere that makes Earth's surface latitude distance in degrees North or South of the equator; run East to West longitude distance in degrees E or West of the Prime Meridian; run North to South map model of Earth's surface as seen from above relief the difference in elevation between the highest and lowest points symbol pictures to stand for features on Earth's surface What are the 3 main landforms? mountains, plains, and plateaus On a topographic map, what does a V-shaped contour line indicate? the contour line is crossing water On a topographic map, how are steep slopes indicated? the contour lines are very close together On a topographic map, how are gentle slopes indicated? the contour lines are spread out Where is the Prime Meridian located? 0 degrees, slightly East of the Atlantic Ocean Where is the Equator located? 0 degrees, between North and South Poles How does a topographic map differ from a road map? a road map shows all roads, a topographic map only shows major roads; there are no contour lines on a road map only on a topographic map What 3 things does a topographic map show? elevation, slope, and relief What is a contour interval? the amount of change in elevation between contour lines What 3 factors determine topography? landforms, relief, and elevation
