The frost line —also known as frost depth or freezing depth —is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt ...
UTC-4 (EDT) The Northeastern United States, also referred to as the Northeast, the East Coast, [b] or the American Northeast, is a geographic region of the United States located on the Atlantic coast of North America. It borders Canada to its north, the Southern United States to its south, the Midwestern United States to its west, and the ...
The south-facing slope on the right side is much drier (receiving more direct sun), and is more sparsely vegetated with the more drought tolerant Artemisia californica and Yucca whipplei. In physical geography and physical geology, aspect (also known as exposure) [1] is the compass direction or azimuth that a terrain surface faces. [2]
While related to soil temperature, it is more accurately associated with the transfer of energy (mostly in the form of heat) throughout the soil, by radiation, conduction and convection. The main soil thermal properties are. Volumetric heat capacity, SI Units: J∙m −3 ∙K −1. Thermal conductivity, SI Units: W∙m −1 ∙K −1.
The soil suborders within an order are differentiated on the basis of soil properties and horizons which depend on soil moisture and temperature. Forty-seven suborders are recognized in the United States. [6] The soil great group category is a subdivision of a suborder in which the kind and sequence of soil horizons distinguish one soil from ...
The tree line follows the line where the seasonal mean temperature is approximately 6 °C or 43 °F. [11] [6] The seasonal mean temperature is taken over all days whose mean temperature is above 0.9 °C (33.6 °F). A growing season of 94 days above that temperature is required for tree growth. [12]
The Northeastern coastal forests are a temperate broadleaf and mixed forests ecoregion of the northeast and middle Atlantic region of the United States. The ecoregion covers an area of 34,630 sq miles (89,691 km 2) encompassing the Piedmont and coastal plain of seven states, extending from coastal southwestern Maine, southeastern New Hampshire, eastern Massachusetts, and Rhode Island ...
Eastern Temperate Forests. The Eastern Temperate Forests is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. The region covers much of the Eastern and Midwestern United States, the U.S. Interior Highlands, and parts of Ontario, Quebec, and the Maritimes.
