The Appalachian temperate rainforest or Appalachian cloud forest is located in the southern Appalachian Mountains of the eastern United States and is among the most biodiverse temperate regions in the world. [ 5][ 7] Centered primarily around Southern Appalachian spruce–fir forests between southwestern Virginia and southwestern North Carolina ...
North Carolina averages 5 inches (130 mm) of snow per winter season. However, this varies greatly across the state. Along the coast, most areas register less than 2 inches (51 mm) per year while the state capital, Raleigh, averages 6.0 inches (150 mm). Farther west in the Piedmont-Triad, the average grows to approximately 9 inches (230 mm).
The physical properties of soil, in order of decreasing importance for ecosystem services such as crop production, are texture, structure, bulk density, porosity, consistency, temperature, colour and resistivity. [ 1] Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand ...
One possible way of assessing soil thermal properties is the analysis of soil temperature variations versus depth Fourier's law, Q = − λ d T / d z {\displaystyle Q=-\lambda dT/dz\,} where Q is heat flux or rate of heat transfer per unit area J·m −2 ∙s −1 or W·m −2 , λ is thermal conductivity W·m −1 ∙K −1 ; dT / dz is the ...
The composition of Ultisol in North Carolina, for reference, is approximately 16% pore space, 2% organic matter and 82% mineral. [9] The use of mulch is widespread in the Piedmont region of the United States as a solution to the high temperatures and saturation of the soil. [10] The addition of mulch helps to make the soil more porous. [11]
A taxonomy is an arrangement in a systematic manner; the USDA soil taxonomy has six levels of classification. They are, from most general to specific: order, suborder, great group, subgroup, family and series. Soil properties that can be measured quantitatively are used in this classification system – they include: depth, moisture ...
Hardiness zone. A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a ...
The Great Appalachian Valley, also called The Great Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trough, including a chain of valley lowlands, and the central feature of the Appalachian Mountains system. The trough stretches about 1,200 miles (1,900 km) from Quebec in the north ...
