Answer: Birds pick up oil on their beaks, by rubbing against the uropygial or preen gland near the tail, and then rub it over their feathers. This makes the water unable to break through the oil.
Explanation: Hope this helps have a great day :)
Answer:
C) the sun's rays that fall on the moon's surface.
Explanation:
The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.
D or a those are the best questions..............XD this question though! anyways see yah later and maybe a brainly?
The answer would be the first one :)
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)
