It is a long, downhill walk (12.6 km) from the youngest rocks (270 Ma) at the rim of the canyon to the oldest rocks (2,000 Ma) at the river. Using this information, estimate how far back in time you would go with each meter along the trail.

a. 158,730 yr/m
b. 1,373 yr/m
c. 1,587 yr/m
d. 137,302 yr/m

Answers

Answer 1

Answer: 137,302 yr/m

Explanation:

Given the information in the question, we can denote that:

Distance= 12.6 km = 12600 meters

The difference between the youngest and the oldest rock is given as:

= 2000 Ma - 270 Ma

= 1730 Ma

Therefore, the number of years that one would go with each meter along the trail will be:

= (1730 × 10^6) / 12600

= 1730000000 / 12600

= 137,302 yr/m

Farm subsidies have supported mainly small farms and have ensured a wide variety of food for consumers is the best statement featuring the farm subsidies in United states.

What is farm subsidy?

Agribusinesses, agricultural organisations, and farms may receive a government incentive known as a farmland subsidy or agricultural incentive in order to boost up their income, control the supply of agricultural commodities, and affect the price and availability of those commodities. Some examples of such goods are wheat, feed grains, cotton, milk, rice, peanuts, sugar, tobacco, oilseeds like soybeans, and meat products like beef, pork, meat, and mutton. 

Farm input subsidies have been utilised for a long time to encourage the use of resources by smallholder farmers, raise incomes, lower food costs, and foster economic growth.

Who is consumer?

Any individual who purchases things or engages services for a consideration that has been paid, promised, partially paid, promised, or under any system of deferred payments is termed a consumer.

If Iceland was considered such a wasteland,
why did the Vikings want it for themselves?

Answers

Answer:

Iceland was not considered as a wasteland by the Vikings that settled in, but the name was given on purpose so that they avoid competition for it.

Explanation:

The Vikings were the first people to reach Iceland. They traveled from their homeland in Scandinavia into the unknown ocean water and eventually managed to reach a large island. Once they got to the island, they made it their base, but also sent expeditions further west, reaching Greenland, and even the North American mainland.

Being aware that there are other groups of Vikings waiting to set sail westward, the first group decided to trick them in order to get better land for themselves. This was done by naming the two large islands they discovered. The green and much more suitable for a living have been named Iceland, while the one covered with ice and much harsher was named Greenland. This made the later groups of Vikings think that Greenland is the better option and they got tricked. Iceland was not a wasteland by any means. It had a lot of timber, freshwater, and an abundance of fish and marine mammals as a food source.

With what???


Answer:

Consider the water balance for a 12 km2 watershed that has the following known inputs
and outputs: annual precipitation 650 mm, annual evapotranspiration 230 mm, and the
average annual discharge for the stream draining the watershed is 0.15 m3
/s.
a. Calculate the net change in the volume of storage (i.e. the water balance), and
express your answer in mm of depth. Clearly explain any assumptions you have to
make. (5 marks)
b. Discuss if you think that renewable water resources in this watershed may be at
risk in the face of climate warming. (2 marks)

Answers

Answer:

a) The net change in the volume of storage is 5.039 million cubic meters.

b) Climate warming may lead to an increase in evapotranspiration rates and a decrease in precipitation rates, reducing net change in the volume of storage and putting that renewable water resources at risk.

Explanation:

a) The net change in the volume of storage ([tex]\Delta V[/tex]), measured in cubic meters, is the sum of inputs and outputs in the watershed, represented by the following expression:

[tex]\Delta V = V_{p} -V_{e}-V_{d}[/tex] (1)

Where:

[tex]V_{p}[/tex] - Added volume due to precipitation, measured in cubic meters.

[tex]V_{e}[/tex] - Subtracted volume due to evapotranspiration, measured in cubic meters.

[tex]V_{d}[/tex] - Subtracted volume due to discharge, measured in cubic meters.

Let suppose that level changes are so small in comparison with the depth of the watershed, then we expand the equation below:

[tex]\Delta V = A\cdot (h_{p}-h_{e})-V_{d}[/tex] (1b)

Where:

[tex]A[/tex] - Watershed area, measured in square meters.

[tex]h_{p}[/tex] - Precipitation, measured in meters.

[tex]h_{e}[/tex] - Evapotranspiration, measured in meters.

If we know that [tex]A = 12\times 10^{6}\,m^{2}[/tex], [tex]h_{p} = 0.65\,m[/tex], [tex]h_{e} = 0.23\,m[/tex] and [tex]V_{d} = 0.15\,m^{3}[/tex], then the net change in the volume of the storage is:

[tex]\Delta V = (12\times 10^{6}\,m^{2})\cdot (0.65\,m-0.23\,m)-0.15\,m^{3}[/tex]

[tex]\Delta V = 5.039\times 10^{6}\,m^{3}[/tex]

The net change in the volume of storage is 5.039 million cubic meters.

b) Climate warming may lead to an increase in evapotranspiration rates and a decrease in precipitation rates, reducing net change in the volume of storage and putting that renewable water resources at risk.
