Slope angle, aspect, and elevation are considered as the primary factors creating spatial variation, causing differences in vegetation growth and distribution, ecosystem functioning, and processes. … In the low-latitudinal region, the slope aspect shows no consistent differences between the opposite aspects.
How does slope affect the ecosystem?
Slope aspect is known to affect the diversity and density of plant communities. Sunny slopes retain less moisture because of stronger solar radiation and higher evaporation. Therefore, plants on sunny slopes, such as grasses, are more likely to be drought- and radiation-resistant.
What is the slope of the terrain?
Terrain slope is defined as the rise and fall of the terrain surface, also known as its inclination or gradient. Slope is a driver and modifier of energy both above and below the water and influences biotic diversity, distribution and the functional traits of those biota.
What is meant by a slope aspect?
Slope is the steepness or the degree of incline of a surface. … Aspect is the orientation of slope, measured clockwise in degrees from 0 to 360, where 0 is north-facing, 90 is east-facing, 180 is south-facing, and 270 is west-facing.
What is Hill ecosystem?
Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. … At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported.
What is the importance of slope in plant production?
So, by cultivating across the slope, you get two good things. First, you save your soil from being washed down to the bottom of the hill. And, second, you’re trapping water all over the field that would otherwise run away – and that water will help your crop grow better.
What is difference between slope and aspect?
What is the difference between slope and aspect? Slope is the distance down the fall line from the top of the slope to its bottom, while aspect is the percentage gradient of this line averaged over its full distance. … Slope is the direction of the fall line, while aspect is the gradient of the fall line.
What is a convex slope?
A terrain feature that is curved or rounded like the exterior of a sphere or circle, i.e. goes from less steep to more steep.
How do you determine the slope?
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
What is the difference between slope and terrain?
As nouns the difference between terrain and slope
is that terrain is territory, ground, while slope is an area of ground that tends evenly upward or downward.
How does slope affect climate?
The aspect of a slope can make very significant influences on its local climate (microclimate). … Similarly, in the northern hemisphere a south-facing slope (more open to sunlight and warm winds) will therefore generally be warmer and drier due to higher levels of evapotranspiration than a north-facing slope.
What is slope and aspect in GIS?
Aspect can be thought of as the slope direction. The values of the output raster will be the compass direction of the aspect, represented by a hue (color). Slope represents the rate of change of elevation for each digital elevation model (DEM) pixel.
How does slope aspect influence evaporation?
Wind played a dominant role in evaporative loss. Depending on the season, evaporative loss was affected more or less significantly by slope aspect. On all quadrants, greatest evaporative loss occurred at the top of slope and least occurred on the lee side of the hill which was most shaded.
What is a pond ecosystem?
A pond or lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. Pond and lake ecosystems are a prime example of lentic ecosystems. Lentic refers to stationary or relatively still water, from the Latin lentus, which means sluggish.
Which soil is found on hill slopes?
Answer: Mountain soil is mainly found on the hill slopes.
What plants are in mountains?
These include grasses, shrubs, alpine flowers, mosses, and lichens. Above the snow line, almost nothing grows. Only the toughest animals can live up there. In each of these zones, plants and animals have special abilities that help them survive.
