Based on the soil texture triangle, the soil with a composition of 25% clay, 25% silt, and 50% sand would be Sandy Clay Loam soil.
These soils are located on steeper slopes (2-3%) as compared to similar soils on the Gently Undulating Plains unit. The soil erosion hazard is high in this soil type because of the poor surface soil structure, the presence of non-wetting sands in some places, the slope, and slope length. The fine sandy clay loam texture and near-sodic nature of the surface soils provide the soils with the propensity to slake and disperse and the tendency to be hard-setting and form surface crusts.
Cropping on these soils presents a higher risk in some years due to soil structure problems resulting in surface water runoff leading to soil erosion.

what is the percentage of the west coast compared to canada
Answer:
80%
Explanation:
The majority of Canada's population is concentrated in the areas close to the Canada–US border. Its four largest provinces by area (Ontario, Quebec, British Columbia, and Alberta) are also its most populous; together they account for 86.5% of the country's population.
Given segment AC bisects angle BAD, angle B is congruent to angle D. Prove segment BC is congruent to segment CD
The proof that BC is congruent to segment CD, where AC bisects angle BAD, angle B is congruent to angle D is given below:
AC bisects ∠BAD, => ∠BAC=∠CAD .................... 1
thus in ΔABC and ΔADC, ∠ABC=∠ADC (given),
∠BAC=∠CAD from 1)],
AC (opposite side side of ∠ABC) = AC (opposite side side of ∠ADC), the common side between ΔABC and ΔADC
Hence,
by AAS axiom, ΔABC ≅ ΔADC,
Therefore, BC (opposite side side of ∠BAC) = DC (opposite side side of ∠CAD), since (1)
Thus, BC=DC proved.

which of the following occurs when the sun, moon, and earth are in alignment (i.e., in opposition or conjunction)?
Whenever the sun, moonlight, and earth are lined up, the tidal ranges are at their greatest.
How do tidal ranges work?The term "tidal range" refers to the height difference between high tide and low tide. The rising and lowering of the tide is frequently accompanied by a horizontal water movement. The values after Morgat correction are: 1.50 - 0.10 Equals 1.40 m of low water. 7.10 - 0.40 ≈ 6.70 m is the high tide.
The significance of tidal range.The seashore is more affected by this phenomenon as the tide range increases. However, the slope of the a beach or even other coastal landform is equally significant since, even in a macro-tidal setting, a steep cliff only offers a minimal difference in the region over which the waves and currents can operate.

in the forest, little sunlight is able to penetrate to the ground through the thick crown cover. as a result, .
In the forest, little sunlight is able to penetrate to the ground through the thick crown cover. as a result, little plant growth is found on the forest floor.
One of the most recognisable aspects of a forest ecosystem is the forest floor, also known as trash, duff, and the O horizon. It mostly comprises of vegetative elements that have been shed, such as leaves, branches, bark, and stems, which are present above the soil surface in varying states of decomposition. The forest floor is primarily made up of non-living organic detritus, although it also contains a broad range of animals and plants. Due to the abundance of decomposers and predators, usually in the form of invertebrates, fungi, algae, bacteria, and archaea, it is one of the most biologically diverse parts of the ecosystem. In tropical woods, where rates of metabolism and species variety are significantly higher than in colder regions, certain plants might be more readily visible.

Underground coal mining is more dangerous and labor extensive compared to _____ mining, so it is also more expensive
Underground coal mining is more dangerous and labor extensive compared to strip mining, so it is also more expensive.
The process of removing coal from the earth is known as mining. Because of its high energy content, coal has been utilized extensively to produce electricity since the 1880s. Coal is used as a fuel in the steel and cement industries to extract iron from iron ore and to make cement.
Environmental concerns have become more significant since 1970, including the health of workers, the degradation of the environment caused by strip mining and mountaintop removal, air pollution, and the impact of coal burning on global warming. By removing the ground above each coal seam, strip mining exposes the coal. The earth that has to be removed is known as "overburden" and is taken out in broad strips.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists.
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Causes and effects of the invention of magnetic reversalScientists don't really know what causes magnetic field reversals, though they have duplicated the phenomenon in laboratory experiments with liquid metals, which would also spontaneously change the direction of their magnetic fields. Some theorists believe that magnetic field reversals could be caused by real events, such as the collision of tectonic plates or the impact of a large meteor or asteroid, but this theory is discounted by others. It is known that leading up to a magnetic reversal, the field strength decreases, and since our current magnetic field strength is now in steady decline, some scientists believe we will see another magnetic reversal in about 2,000 years.
If, as some scientists have suggested, there was a period in which there was no magnetic field at all before the reversal occurred, the effect on the planet is not well understood.
Some theorists suggest that having no magnetic field would expose the Earth's surface to harmful solar radiation that could potentially cause the global extinction of life. However, there are currently no demonstrable statistical correlations in the fossil record to verify this. The last reversal occurred around 780,000 years ago, and there is no evidence to suggest that there was a mass species extinction at that time. Other scientists argue that the magnetic field does not dissipate during a reversal, but only grows weaker temporarily.

According to a 2014 report conducted by yale university and George Mason university, the majority of the public surveyed in the united states agreed that global warming is occurring, and 50% believed it was caused primarily by human activities.
Using fossil fuels like coal and oil has increased the quantity of carbon dioxide in the atmosphere during the last century (CO2). This increase is the consequence of burning coal or oil, which creates CO2 when oxygen and carbon dioxide in the air combine. A rise in greenhouse gas concentrations has been mostly attributed to the clearance of land for industrial, agricultural, and other human endeavors which in turn contributes to Global warming.
The industrial activity on which our modern civilization depends have raised atmospheric carbon dioxide levels by over 50% since 1750. The spike in temperature may be attributed to human activities, according to a distinct isotopic fingerprint that researchers have found in the atmosphere.

Which of the following accurately describes ^18 O / ^16 O ratios of the oceans? Because ^18O evaporates more readily than ^16O. the oceans have a higher relative abundance of ^16O during the summer. The ^18O/^16O ratio in the ocean is low during the winter because temperatures are too low for ^16O to evaporate During the winter. ^16O is high in the ocean; during warmer periods the isotope ratio is lower The ratio of oceanic ^18O/^16O in the late summer is high, because the most of the ^16O has evaporated by then.
The option that accurately describes ^18 O / ^16 O ratios of the oceans is option D) During periods of colder temperature 16O is locked up in snow and ice and the oceans have a higher preponderance of 18O; during warmer periods the isotope ratio of 16O to 18O is higher.
What does the Redfield ratio tell us?The Redfield ratio measures the proportions of several chemical components found in typical phytoplankton biomass. It specifies how photosynthesis and remineralization reactions stoichiometry.
In global circulation models, the Redfield ratio is essential for calculating the fluxes of carbon and nutrients. If there is a limiting nutrient in a localized system, they also aid in identifying which nutrients are it.
Therefore, one can say that High oceanic delta-O-18 values correspond to cold climates, while low values correspond to warm climates. The results of precipitation and evaporation result in this trend. In warm, tropical regions, the ocean is high in 18O because 16O evaporates earlier due to its lesser weight than 18O.
