A period.
the shortest geologic time interval is a period.
Notice the pattern around that contour line. Then determine the interval that the surrounding contour lines are increasing or decreasing by. Ex. 50 100 150 200, the contour interval would then be 50
There are 100 intervals (degrees) between the freezing and boiling points of water on the Celsius (centigrade) scale. These "degrees" are therefore 1.8 times as large an interval as the "degree" defined on the Fahrenheit scale.
The definition of a contour interval is the difference in elevation between two consecutive lines.

Acceleration has two parts ... its size and its direction.To find the size (magnitude):-- pick a time interval-- measure the speed at the beginning of the interval-- measure the speed at the end of the interval-- subtract the speed at the beginning from the speed at the end-- divide that difference by the length of the time interval-- the result is the magnitude of acceleration during that time interval
f(x) is decreasing on the interval on which f'(x) is negative. So we want: (x2-2)/x<0 For this to be true either the numerator or the denominator (but not both) must be negative. On the interval x>0, the numerator is negative for 0<x<sqrt(2) and the denominator is positive for all x>0. On the interval x<0, the denominator is negative for all values on this interval. The numerator is positive on this interval for x<-sqrt(2). So, f' is negative (and f is decreasing) on the intervals: (-infinity, -sqrt(2)), (0, sqrt(2))
If the first derivative of a function is greater than 0 on an interval, then the function is increasing on that interval. If the first derivative of a function is less than 0 on an interval, then the function is decreasing on that interval. If the second derivative of a function is greater than 0 on an interval, then the function is concave up on that interval. If the second derivative of a function is less than 0 on an interval, then the function is concave down on that interval.
Acceleration = (speed at the end of some time interval minus speed at the beginning of the interval)/(length of the time interval)
increasing the interval would decreasing the degrees of accuracy of the graph, optically the line seem flatter
