most of the agricultural productivity of the united states and canada is concentrated in which two physiographic regions?
Answers
United States and Canada agricultural productivity is mostly concentrated in Interior Lowlands and Great Plains region.
Agriculture has been practiced on the Interior Lowlands' rich soil for a very long time. Native Americans from this region, along with the Omaha, cultivated and traded several various types of corn. Today, corn and soybeans are planted on the majority of agricultural area in the Interior Lowlands. Farmers' growing seasons are getting longer due to climate change, but the Lowlands are at risk from an increase in the frequency of extreme phenomena like floods, heat waves, and droughts.
The cultivation of agricultural products like alfalfa, barley, corn, hay, soybeans, and wheat as well as livestock including beef cattle and a few dairy cows, hogs, and sheep is all related to agriculture in the Great Plains.

what is the primary cause of deep currents in the ocean?
Answers
The primary cause of deep currents in the ocean is the sinking of dense, cold water at high latitudes due to the cooling and increased salinity of surface waters.
This process is known as thermohaline circulation, or the ocean conveyor belt. In polar regions, seawater is cooled by cold air temperatures and ice formation, which increases its density. Additionally, as sea ice forms, it expels salt, making the surrounding seawater even saltier and denser. This dense, cold water sinks and begins to flow towards the equator, where it eventually upwells to the surface and begins the cycle again. The sinking of this dense water initiates a slow, deep ocean current that can transport vast amounts of water and heat around the globe. These deep currents play an important role in regulating the Earth's climate by transporting heat from the tropics to the poles and vice versa.

2x² 18x +36 =
Answers
Answer:
The factorization of 2x² + 18x + 36 is (2x + 12)(x + 3). To factor this equation, use the method of factoring by grouping. Group the terms into two binomials and then factor each binomial. The first binomial is (2x + 12) and the second binomial is (x + 3). Then factor each binomial using the difference of squares formula (a² - b² = (a + b)(a - b)). For the first binomial, the a value is 2x and the b value is 12. This gives us (2x + 12) = (2x + 12)(2x - 12). For the second binomial, the a value is x and the b value is 3. This gives us (x + 3) = (x + 3)(x - 3). Multiplying the two binomials together gives us (2x + 12)(x + 3) which is the factorization of 2x² + 18x + 36.

in addition to wind speed, what other factors influencing sea and river levels could affect the height of the storm surge at a given place and hour?
Answers
The factors influencing sea and river levels could affect the height of the storm surge at a given place and hour are atmospheric pressure, location of the surge, intensity of the wind, the shape of shore line.
In meteorology, wind speed, also known as wind flow speed, is a fundamental atmospheric quantity brought on by air shifting from a state of high to low pressure, frequently as a result of temperature changes. Nowadays, an emometer is used frequently to measure wind speed.
Numerous other things, including construction projects, aviation and maritime operations, plant growth and metabolism rates, and weather forecasting, are all impacted by wind speed. Due to the rotation of the Earth, wind direction is typically almost perpendicular to isobars (as opposed to perpendicular, as one might expect).
Numerous circumstances and factors, operating on various scales, influence wind speed. These consist of the pressure gradient, Rossby waves and jet streams, as well as the local weather. Along with the pressure gradient and the terrain, there are other connections between wind speed and wind direction.
The phrase "pressure gradient" refers to the difference in air pressure between two locations, either on the Earth's surface or in the atmosphere. It is important for wind speed because, in order to balance out the variation, the wind must move more quickly from areas of high pressure to areas of low pressure. Along with the Coriolis effect and friction, the pressure gradient also affects the direction of the wind.In the upper troposphere, Rossby waves are powerful winds. These are transnational and move from the West to the East. In contrast to the lower troposphere, the Rossby waves themselves have a different wind speed.The formation of hurricanes, monsoons, and cyclones as freak weather conditions can significantly alter the flow velocity of the wind, so local weather conditions are important in determining wind speed.Learn more about Wind speed, here

What was the peak wavelength of the background radiation at the time that light left the most distant galaxies that we can see. Assume that these galaxies are observed to be at a redshift z=12. What is the temperature corresponding to that peak wavelength?'
Answers
The temperature corresponding to that peak wavelength is 3.717 x 103 K.
The peak wavelength of the background radiation at the time that light left the most distant galaxies we can see (redshift z=12) can be calculated using the equation
λ = 2.998 x 10-3/(1 + z).
Inserting z=12 yields a peak wavelength of
λ = 2.498 x 10-4 m.
The temperature corresponding to this peak wavelength can be calculated using the equation T = hc/λk where h is Planck's constant, c is the speed of light, λ is the peak wavelength, and k is Boltzmann's constant.
Inserting the given values yields a temperature of T = 3.717 x 103 K.

you live on a coastline and a large hurricane may strike nearby. you measure the air pressure over several hours and see that the air pressure is gradually falling. is the hurricane coming towards you or moving away?
Answers
If the air pressure is gradually falling, that means the hurricane is moving toward you.
Hurricane is a rotating storm system that's characterized by strong winds, a low-pressure center, and spiraling thunderstorms that produce heavy rains. In general, hurricanes are steered by global winds, especially tropical winds near the equator.
In hurricanes, the warm ocean air rises into the storm and forms an area of low pressure underneath it. It causes more air to rush in. The center of a hurricane has the lowest air pressure compared to the surrounding area. Therefore, if the air pressure is gradually dropping in the place where you're measuring it, that means the hurricane is moving toward you

Which of the following is a characteristic of a newly isolated forest fragment?
Group of answer choices
Species richness remais stable because the forest fragment is still surrounded by terrestrial matrix
Species losses occur rapidly because very few species can cross the matrix
Species losses occur slowly because species can still cross the surrounding matrix
Species richness increases over time as species colonize the fragment
Species losses occur slowly because invasive species emigrate to forest fragments
Answers
The characteristic of a newly isolated forest fragment is best described by the "Species losses occur rapidly because very few species can cross the matrix." Therefore, option B is correct.
When a forest fragment becomes isolated, it loses its connectivity to the surrounding habitat or matrix. This isolation restricts the movement and dispersal of species between the fragment and the larger landscape. As a result, the ability of species to migrate or colonize the fragment becomes limited.
The lack of connectivity with the surrounding matrix makes it difficult for many species to reach the forest fragment, resulting in rapid species losses. The reduced gene flow and limited availability of resources in the isolated fragment further contribute to these losses.
Option A, stating that species richness remains stable because the forest fragment is still surrounded by a terrestrial matrix, is incorrect. Isolated forest fragments typically experience a decline in species richness due to the aforementioned factors.
Option C, suggesting that species losses occur slowly because species can still cross the surrounding matrix, is also incorrect. The isolation of the fragment hinders species movement, leading to relatively rapid losses.
Option D, stating that species richness increases over time as species colonize the fragment, is inconsistent with the scenario of a newly isolated forest fragment. Colonization and species richness increase are more likely to occur in older, well-established fragments that have developed suitable conditions for species to thrive.
Option E, suggesting that species losses occur slowly because invasive species emigrate to forest fragments, does not align with the characteristic of a newly isolated fragment. Invasive species are more likely to pose a threat to fragmented habitats in the long term rather than immediately after isolation.
In conclusion, when a forest fragment becomes newly isolated, a characteristic is the rapid loss of species due to the limited ability of species to cross the surrounding matrix. This loss of connectivity and restricted movement of species significantly impact the biodiversity of the isolated fragment. Therefore, option B is correct.

which natural phenomenon is associated with deflation
Answers
Deflation is a natural phenomenon that is associated with the erosion or removal of fine-grained sediment from the surface of the Earth by wind.
When wind blows over loose or unconsolidated sediment such as sand, silt, or clay, it can lift and transport these materials, leading to the gradual lowering of the land surface. This process is known as deflation, and it can lead to the formation of desert pavement, a layer of closely packed rocks and pebbles that forms on the surface of the land after the finer-grained sediments have been removed.
Deflation can also lead to the formation of sand dunes, which are formed when sand is transported and deposited in a specific location by wind. Deflation is a common process in arid and semiarid regions where vegetation cover is low and the land surface is composed of loose, easily erodible sediments.

if plate techtonic processes form a chain of high mountains, would you expect atmospheric co2 to increase or decrease?
Answers
If all else is equal, the rate of chemical weathering and erosion should increase as mountains rise.
How does the concentration of CO2 affect plate tectonics?Plate tectonics is a major driver of the long-term carbon cycle since it is responsible for CO2 degassing at ridges & arcs, CO2 return to the mantle through subduction, and bringing fresh, weatherable rock to the surface via uplift and orogeny.
If plate tectonic processes produced a series of tall mountains, which do you believe would happen to atmospheric CO2?If all other variables are held constant, the rate of chemical weathering and erosion should accelerate with mountain height. The chemical weathering of continental rocks ought to cause a decrease in atmospheric CO2 levels.
