On topographic maps, how does the spacing of contour lines relate to continental and ocean-floor topography? A. For both contine
Trava [24]

For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.

Explanation:

The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.

The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.

Some elements of the contour lines or that go with them to give better representation are:

  • black dots (representing a top)
  • thicker lines (every fifth, so that the counting is faster and easier)
  • small lines with given direction (representing cliffs or highly steep slopes)
  • numbers (providing information about elevation)

Why do you think root hairs are produced only on the part of the root system that has stop?​
mixer [17]

Answer:

Explanation:

They are found only in the zone of maturation, and not the zone of elongation, possibly because any root hairs that arise are sheared off as the root elongates and moves through the soil. Root hairs grow quickly, at least 1μm/min, making them particularly useful for research on cell expansion.
