Graph it -
if it's curving up then the gradient is increasing.
OR take it's derivitive.
If the gradient is a positive number the curve is increasing, and if the gradient is a negative number it is decreasing.
I don't know, but they are probably decreasing due to global warming and all.
Simply look at the number!
Each index contour has an elevation associated with it. When you look at 2 contours, one will have a higher corresponding elevation. As you go from the lower elevation to the higher elevation, you know that the land is increasing in the direction toward the higher elevation. From the higher to the lower elevation, the land is decreasing (sloping downward, decreasing in elevation).
Firstly, and most simply, it may lead to another part of a problem or question or context.Secondly, and importantlyest, (i just invented that word it means most importantly) It can be used to find the gradient of a curve.As you may know, the gradient of a straight line is constanty=mx+c the gradient is mBut for a curve, the gradient is always changing.look at a graph of y=x2 and you will see that an infinite tangents make up the curve each with a different value for m.In short, when you differentiate a function or equation, you get the gradient function, which allows you to find the gradient at any point on the graph y=f(x)differentiate y=x2 (which is the same as find dy/dx)dy/dx=2xso the gradient on the curve y=x2 always 2 times the x value in question. At x=1 the gradient is 2. At x=2 the gradient is 4.In mechanics, if you draw a graph of displacement against time for a moving object, the GRADIENT is equal to the function of velocity. Plot velocity against time and the gradient is equal to Acceleration against time.In any circumstance where a curve is involved differentiation is needed to ind a gradient.Phew, hope that helps and answers your question
You look at the contours. Steeply sloping contours with numbers that are increasing usually indicate that the height is increasing, and may be an indicator for hills. Contrastingly, steeply sloping contours with decreasing numbers indicate a decreasing altitude, and may indicate a depression or a valley.
As we know law of variable proportion means as we increase the quantity of one input keeping other input fix... the Total physical product increase @ increasing rate than increase at decreasing rate than at decreasing rate.... and cost curve is totally dependent upon total variable cost curve.... so if the output is increasing this is due to increase in variable factors( labors) and if labors increase the cost will be obviously more as the labor increase....+
Index contours are thicker and usually labeled with their elevation. By identifying the index contours on a topographic map, you can determine if the land is increasing or decreasing in elevation. If the index contours are closer together, the land is steep, indicating a rapid change in elevation. Conversely, if the index contours are further apart, the land is gradually increasing or decreasing in elevation.
You can tell if the moon is increasing or decreasing in light by observing its shape in the sky. During a waxing moon, it will appear to be growing larger, while during a waning moon, it will appear to be shrinking. Additionally, a waxing moon will be visible in the evening, while a waning moon will be visible in the morning.
they know when to migrate because of the weather and the food decreasing
We don't know what curve you're talking about.
