John Wesley Powell, in his Report on the Lands of the Arid Regions of the United States (1878), famously stated that massive cooperation under government control was the only way farming would succeed on the Great Plains.
Who is John Wesley Powell?John Wesley Powell, (born March 24, 1834, Mount Morris, New York, U.S.—died September 23, 1902, Haven, Maine), American explorer, geologist, and ethnologist, best known for his exploration of the upper portion of the Colorado River and the Grand Canyon.
In 1878, Powell published his Report on the Lands of the Arid Region, which laid out a concrete strategy for settling the West without fighting over scarce water. Powell wanted to stall the waves of homesteaders moving across the plains and mountains.
Instead, he wanted to plan settlement based in part on the cooperative model practiced in Utah by Mormon settlers, who tapped mountain snowmelt and the streams, lakes and rivers it created with irrigation ditches leading to crops. Powell wanted to organize settlements around water and watersheds, which would force water users to conserve the scarce resource, because overuse or pollution would hurt everyone in the watershed.
Powell believed this arrangement would also make communities better prepared to deal with attempts to usurp their water.
Therefore, we can conclude that the correct option is C.

The pollutant responsible for major declines in the populations of pelicans, ospreys, and other marine birds was __________.
The pollutant responsible for major declines in the populations of pelicans, ospreys, and other marine birds was DDT.
A pollutant or novel entity is a substance or energy that is introduced into the environment and causes undesirable effects or reduces the usefulness of a resource. These can be of both natural and anthropogenic origin. Contaminants can pollute the environment or become a public health problem when they reach levels high enough to cause significant adverse effects.
Pollutants can cause long-term or short-term harm by altering the growth rates of plant and animal species and by affecting human comfort, well-being, health, and property values. There is nature. Some contaminants are biodegradable and therefore do not remain in the environment for long periods of time. However, the decomposition products of some contaminants are themselves contaminated, such as the products DDE and DDD resulting from the decomposition of DDT.
Pollution has far-reaching negative effects on the environment. When analyzed in terms of planetary boundaries, human societies have unleashed new entities far beyond their safe levels.

Ocean basins are created along blank______ boundaries that break apart continental lithosphere.
Ocean basins are created along blank convergent boundaries that break apart continental lithosphere.
Converging boundaries produce foreland basins through tectonic compression of oceanic and continental crust during lithospheric flexure. The collapse of the rift zone or the emergence of an ocean might result from tectonic extension at divergent borders when continental rifting is taking place.
The North Sea is an illustration of a basin created by lithospheric stretching; it is also a prominent site for considerable hydrocarbon deposits. Another comparable feature is the Basin and Range province, which forms a sequence of horst and graben formations and occupies the majority of the US state of Nevada.

How does stable air differ from unstable air? What weather conditions would lead you to believe that air is unstable?
Stable air differ from Unstable air and the weather conditions would lead you to believe that air is unstable
When compared to unstable air, stable air is more resistant to upward motion. When stable air is made to rise, it often forms thin clouds that only sometimes provide light to moderate precipitation. On the other hand, when unstable air rises, clouds are frequently towering and heavy precipitation is possible.
When the air in a mass of air is warmer and/or more humid than the air above it, the air is said to be unstable in the lowest levels of the mass. The air will rise as a result because the air parcel is warmer than the air around it at that time. The weather can shift abruptly and become violent in an unstable setting.

Why are western boundary currents intensified compared to eastern boundary currents?
One reason for the westward boundary intensification of boundary currents has to do with the intensification of the Coriolis effect with latitude. The Coriolis effect is stronger at western latitudes than at trade wind latitudes.
The Kuroshio is the western boundary current of the subtropical gyre in the North Pacific and requires comparison with its Atlantic counterpart, the Gulf Stream.
The Western Boundary Current is a strong, narrow current confined to the western side of the basin. In the North Atlantic, the Gulf Stream is the western boundary current of the anticyclonic subtropical gyre, and the North Atlantic Current (NAC) is its northeastern extension (Arhan, 1990; Rossby, 1996).
In fact, they are one of the fastest surface currents in the ocean. One reason for the westward amplification of boundary currents has to do with the amplification of the Coriolis effect with latitude. The Coriolis effect is stronger at western latitudes than at trade wind latitudes.

The correct option is a. natural lake that is dry for long periods of time.
What is playa?Playas are flat-bottomed depressions that are sometimes surrounded by water which it slowly seeps into the groundwater system or vaporizes into the atmosphere. As a result, salt, sand, and mud are deposited along the depression's bottom and around its edges.
Some key feature of playa are-
Playas are also known as pans, flats, or dry lakes. They are typically found in inner desert watersheds and close to coasts in arid and semi-arid regions.The flattest recorded landforms are playas. Typically, their gradients are less than 0.2 meters per kilometer. Many kilometers of surface may be submerged when only a few centimeters of water are added. The nearly flawless flatness that is so distinctive of these dry region landforms is developed and maintained by the process of flooding.The middle, level basins of arid plains are called playas. They need drainage from the inside to a place where evaporation far outweighs intake. A playa lake arises when the area is inundated, concentrating salts and fine-grained debris.

When are upper air winds fastest? anytime surface temperature gradients are weak in summer in winter these winds maintain about the same speed throughout the year.
In winter the upper air winds fastest .
Why wind speed higher in winter ?
Temperature differences between air masses lead to pressure differences and this produces wind. The winter brings higher temperature gradients especially when cold fronts move in from polar regions and this causes wind speeds that are higher than normal.
Since the wind direction at the higher level is parallel to the isobars and its speed is greater than surface wind this transfer causes the surface wind to veer and increase in speed.

Why is the mesosphere colder than the thermosphere, even though it's closer to earth?
Answer:
Mesosphere lies in between 50 to 80 km above the earth surface and due to low density gases escape easily and hence it is colder.
Explanation:
Mesosphere has the capacity to not absorb the infrared radiation that's why the gases reflected from the earth surface escape the layer of mesopause and goes inside the thermosphere.
In the thermosphere, even the minute atoms of gases ca be absorbed by the layer which increases the air temperature and the air rises up hence making thermosphere as the hottest layer in the atmosphere.
