What does a a V shaped contour line mean when it points up hill?
A V-shaped contour line that points uphill indicates that there is a river or stream flowing in that direction. The apex of the "V" points upstream, while the open end points downhill. This shape signifies a valley or a low area where the water flows, helping to identify the landscape's drainage patterns.
What is the physical interpretation of gradient of a scalar field and directional derivative?
The elevation of points on a hill is a scalar 'field'. It can have a different value at every point, but each one is a scalar value. Imagine a lumpy bumpy irregular hill, and pick a point to talk about, say, somewhere on the side of the hill. At that point, the directional derivative of the elevation is the rate at which the elevation changes leaving the point in that direction. It has different values in different directions: If you're looking up the hill, then the d.d. is positive in that direction; if you're looking down the hill, the d.d. is negative in that direction. If you're looking along the side of the hill, the d.d. could be zero, because the elevation doesn't change in that particular direction. The directional derivative is a vector. The direction is whatever direction you're talking about, and the magnitude is the rate of change in that direction. The gradient is the vector that's simply the greatest positive directional derivative at that point. Its direction is the direction of the steepest rise, and its magnitude is the rate of rise in that direction. If your hill is, say, a perfect cone, and you're on the side, then the gradient is the vector from you straight toward the top, with magnitude equal to the slope of the side of the cone. Any other vector is a directional derivative, with a smaller slope, and it isn't the gradient.
What is the height of the hill if the elevation of a hill at a place due east of it is 39 degrees at a place B due south of A the elevation is 27 degrees and the distance from A to B is 500m?
It is not clear from the question where the point A is. This answer assumes that A is the point to the East of the hill. Suppose the height of the hill is h metres. Suppose O is the point, on ground level, under the apex of the hill. Then tan(39) = h/OA so that OA = h/tan(39) Also tan(27) = h/OB so that OB = h/tan(27) Now, triangle OAB has a right angle at A, so by Pythagoras, OB2 = OA2 + AB2 Therefore h2/tan2(27) = h2/tan2(39) + 5002 that is h2/0.2596 = h2/0.6558 + 250000 so that 2.3269h2 = 250000 h2 = 107441 h = 327.8 metres.
What is the approximate gradient of the hill between points x and y?
The approximate gradient of the hill between points x and y can be calculated by taking the difference in elevation between the two points and dividing it by the horizontal distance between them. This is often expressed as the rise over run. If the elevation at point x is higher than at point y, the gradient will be negative, indicating a downhill slope, while a positive gradient indicates an uphill slope. The steeper the hill, the larger the absolute value of the gradient.
How do you write the word HIll in shorthand?
In shorthand, the word "Hill" is typically represented by a simple stroke that resembles a small upward curve or a loop, often combined with a dash or mark to indicate the "H" sound. The specific representation can vary depending on the shorthand system being used, such as Gregg or Pitman. It's essential to refer to the specific shorthand dictionary or guide for the system you're using for accurate representation.
How can you tell from the map which point on the hill is the highest?
Look for the point where contour lines are closest together or where the numbers on the contour lines are highest. This indicates the highest elevation on the hill.
Why isn't the highest point on a hill or a mountain represented by contour line?
The highest point on a hill or mountain may not be represented by a contour line if the peak is a single point or if it is very small compared to the interval of the contour lines. Contour lines connect points of equal elevation, and if the elevation changes rapidly at the peak, the line might not accurately reflect that high point. Additionally, if the peak is part of a broader area of equal elevation, the contour lines may not capture the exact summit. In some cases, the highest point is marked with a symbol or label instead.
Why isn't the highest point on a hill or a mountain represented by a contour line?
The highest point on a hill or mountain is typically represented by a closed contour line, which indicates that all points along that line are at the same elevation. However, if a peak is very sharp or pointed, it may not be clear in contour mapping, especially if the contour intervals are large. Additionally, if the peak is too small to be captured accurately at the given scale, it may not appear as a distinct line. In such cases, the highest point may simply be marked with a point symbol or label instead.
Why isnt the highest point on a hill or a mountain represented by a contour line?
The highest elevation point is represented by a number...number of feet above sea level. At the very top, there is a point/peak. In order to make sense, a contour line has to represent a relative elevation all the way around the circumference of the mountain. The lines are not circles and where they are wavy, this indicates places where the mountain juts out.
What will a hill look like on a topographic map?
On a topographic map, a hill is represented by contour lines that are closely spaced together, indicating a steep slope. The lines form concentric circles, with the innermost circle representing the highest point of the hill. As the elevation decreases, the contour lines become wider apart. The overall pattern provides a visual representation of the hill's shape and steepness.
What is the highest point of a hill called?
The highest point of a hill is called its summit.
What is the elevation of the highest contour line on hill w?
The elevation of the highest contour line on hill W is the value indicated on that specific contour line, representing the peak of the hill. On a topographic map, contour lines are used to show the elevation and shape of the land, with each line representing a specific elevation.
What does a series of closed contour lines most likely represent?
A series of closed contour lines most likely represents a landform, such as a hill or depression, on a topographic map. When the lines are spaced closely together, they indicate steep terrain, while wider spacing suggests gentler slopes. The innermost closed contour typically signifies the highest point of a hill or the lowest point of a depression.
The highest point on a hill shown on a contour map is?
The level curves form loops around the maximum point. As height increases the loops become tighter. Similarly the curves squeeze to the lowest point as height decreases.
Contour lines that form a circle indicate?
Contour lines forming a circle on a topographic map indicate a hill or summit. This circular pattern of contour lines represents a peak with increasingly lower elevations as you move outward from the center of the circle. This can help in identifying the highest point in a specific area.
What is the pattern of the contour lines around a simple hill?
Contour lines around a simple hill form concentric closed loops, with each loop representing a specific elevation. The lines are closer together and more tightly packed at steeper parts of the hill and farther apart on gentler slopes. The highest point of the hill is indicated by the smallest closed loop.
What is the meaning of 'summit?
Highest point, hill top, hill peak.
