What does it mean if your contour lines are close together?
What does it mean if your contour lines are close together?
slope
Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicates a slope that is relatively flat.
Are contour lines the same as isobars?
Topographic maps show variations in the elevation of a land surface. The contour lines connect lines of equal elevation. Other commonly used contour maps include weather maps showing temperature values as bands of color (temperature lines are called isotherms) or barometric pressure as contour lines (called isobars).
When lines on an isobar map are very close together this may be an indication of what kinds of weather?
You’ll often notice the isobars are very close together around a low, indicating stronger winds. Find out about two particularly intense types of low pressure systems: east coast lows.
Why contour lines are spaced close together on a steep slope?
Closely-spaced contour lines indicate a steep slope. They show that the elevation changes quickly over a short horizontal distance.
Are isotherms and and isobars the same?
Isotherms are lines of equal temperature. You can think of isobars the same way, except that “bar” means pressure. Isobars are lines of equal pressure.
What is difference between isotherm and isobar?
As nouns the difference between isotherm and isobar is that isotherm is a line of equal or constant temperature on a graph or chart, such as a weather map while isobar is (meteorology) a line drawn on a map or chart connecting places of equal or constant pressure.
What are isobar lines?
isobar, line on a weather map of constant barometric pressure drawn on a given reference surface. The isobaric pattern on a constant-height surface is extremely useful in weather forecasting because of the close association between pressure and weather.
What do isobar lines on a weather map indicate?
Isobars are lines on a weather map that join places of equal pressure. Meteorologists collect information from weather stations, buoys and ships and then draw smooth curves to join the dots. Atmospheric pressure is measured by barometers in hectopascals (hPa), and there is a 4 hPa difference between isobars.
What is the other name of contour lines?

What type of topography has contour lines very close together?
If contour lines are close together, it is a very steep slope; if they are far apart, it is a gradual slope.
What is the difference between isobars and isotherms?
On a weather map, isobars are contour lines that connect different locations or points with the same constant pressure, while isotherms are also contour lines, which specify locations that are at the same constant temperature.
What are isobars weather?
Isobars are lines on a weather map that represent areas with equal atmospheric pressure. Each isobar line follows a path through locations with an equal atmospheric pressure that is plus or minus four starting with 1000 millibars.
What do contour lines represent?
A series of concentric contour lines that are closed onto themselves indicate mountains or hills.
