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 ...
Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand.
The composite is then converted into an AP score of 1-5 using a scale for that year's exam. [5] Students generally receive their scores by mail in mid-July of the year they took the test. Scores can be viewed on the College Board website using My AP. Alternatively, they can receive their scores by phone as early as July 1 for a fee. [6]

The most common purpose of a thematic map is to portray the geographic distribution of one or more phenomena. Sometimes this distribution is already familiar to the cartographer, who wants to communicate it to an audience, while at other times the map is created to discover previously unknown patterns (as a form of Geovisualization).

Horseradish is perennial in hardiness zones 2–9 and can be grown as an annual in other zones, although not as successfully as in zones with both a long growing season and winter temperatures cold enough to ensure plant dormancy. After the first frost in autumn kills the leaves, the root is dug and divided.
[62] [63] A bioregion is defined along watershed and hydrological boundaries, and uses a combination of bioregional layers, beginning with the oldest "hard" lines; geology, topography, tectonics, wind, fracture zones and continental divides, working its way through the "soft" lines: living systems such as soil, ecosystems, climate, marine life ...
Advanced Placement (AP) examinations are exams offered in United States by the College Board and are taken each May by students. The tests are the culmination of year-long Advanced Placement (AP) courses, which are typically offered at the high school level. AP exams (with few exceptions [1]) have a multiple-choice section and a free-response ...
