The map shows a top view of the Mississippi River. The gap between lines 1 and 2 shows how much Saint Anthony Falls receded between 1680 and 1766. The gap between lines 3 and 4 shows how much the falls receded between 1856 and 1876. At what rate (on average) did the falls recede during each of these time spans? Express your answer in units of feet per year. Did the rate increase or decrease from one time span to the next? Hint: Determine how many years passed between lines 1 and 2 and between lines 3 and 4 to help you find your answers.

Answers

Answer 1

Answer:

Final answer:

The average rate of recession can be calculated by dividing the total distance receded by the number of years in each time span. The rate increased or decreased depending on these calculations.

Explanation:

To answer this question, we first need to know exactly how far the Saint Anthony Falls receded between the specified times. However, if we assume those distances are provided (in the form of the gaps on the map, expressed in feet), the student can calculate the rate of recession by dividing the total distance receded by the total number of years for each time span. For example, if the falls receded 86 feet between 1680 and 1766, that's 86 feet/86 years = 1 feet/year. If it receded 120 feet between 1856 and 1876, that's 120 feet/20 years = 6 feet/year. In this hypothetical example, the rate increased from the first time span to the next.

Again, it's crucial to know the exact distances receded (the lengths of the gaps on your map) to compute the accurate rates of recession.

Answer 2

Answer:

Answer:

The time span between 1680 and 1766 (lines 1 and 2) is 86 years: 1766 − 1680 = 86 years. During this time, the falls receded an average of 5.8 feet per year: 500 feet ÷ 86 years ≈ 5.8 feet per year.

The time span between 1856 and 1876 (lines 3 and 4) is 20 years: 1876 − 1856 = 20 years. During this time, the falls receded an average of 25 feet per year: 500 feet ÷ 20 years = 25 feet per year.

Answers

You could challenge the premise of the question - what exactly is the crisis? It is easier to argue that humanity has actually avoided resource crises due to its continued and proven capacity for innovation. For instance, agricultural productivity expanded tremendously in the twentieth century. Whereas the majority of workers in Western societies were employed in agriculture in 1900, by 2000 that proportion was under 5%. Improved cultivation methods, the mechanization of farm implements, the tailoring of crops to specific soil types, crop rotation, improved irrigation, and the development of genetically modified crops selected for their productivity and resistance to pests have all enabled the output per person per acre to expand tremendously and support the massive global population growth seen over the past century.

Why is the tundra considered a desert? and what is a vertical feeding pattern?

Answers

The tundra is considered a desert because of its dry, cold weather. The amount of flora in a tundra is comparable to that of a desert, little to none. A vertical feeding pattern is when an animal or person eats while standing up.

A desert is an area that receives very little precipitation (rain or snow), and
has very sparse vegetation. Tundra fits this description.

"Vertical feeding pattern" in an area means that different species are able to
coexist there because some of them feed from the ground or down near it ...
like eating grass, bugs, or small rodents ... while other species feed from
higher up ... eating like leaves, tree fruits, or birds.
