  2. Environmental gradient - Wikipedia

    en.wikipedia.org/wiki/Environmental_gradient

    Environmental gradients can be related to factors such as altitude, depth, temperature, soil humidity and precipitation. Often times, a multitude of biotic (living) factors are closely related to these gradients; as a result of a change in an environmental gradient, factors such as species abundance , population density, morphology , primary ...

  3. Climatic geomorphology - Wikipedia

    en.wikipedia.org/wiki/Climatic_geomorphology

    Atolls like Atafu in Tokelau in the Pacific Ocean are landforms associated to tropical climate. No atoll exists outside the tropics. Climatic geomorphology is the study of the role of climate in shaping landforms and the earth-surface processes. [1] An approach used in climatic geomorphology is to study relict landforms to infer ancient ...

  4. Aspect (geography) - Wikipedia

    en.wikipedia.org/wiki/Aspect_(geography)

    In physical geography and physical geology, aspect (also known as exposure) [1] is the compass direction or azimuth that a terrain surface faces. [ 2 ] For example, a slope landform on the eastern edge of the Rockies toward the Great Plains is described as having an easterly aspect .

  5. Altitudinal zonation - Wikipedia

    en.wikipedia.org/wiki/Altitudinal_zonation

    Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.

  6. Effects of climate change on biomes - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    Climate change has a direct impact on the productivity of the boreal forest, as well as health and regeneration. [15] As a result of the rapidly changing climate, trees show declines in growth at the southern limit of their range, [ 59 ] and are migrating to higher latitudes and altitudes (northward) to remain their climatic habitat, but some ...

  7. Climate - Wikipedia

    en.wikipedia.org/wiki/Climate

    Climate (from Ancient Greek κλίμα 'inclination') is commonly defined as the weather averaged over a long period. [9] The standard averaging period is 30 years, [10] but other periods may be used depending on the purpose. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations.

  8. Elevational diversity gradient - Wikipedia

    en.wikipedia.org/wiki/Elevational_Diversity_Gradient

    The first recorded observation of the elevational diversity gradient was by Carl Linnaeus in his treatise On the growth of the habitable Earth.In this document, Linnaeus based his predictions on flood geology, assuming most of the world was at one point inundated, leaving only the highest elevations available for terrestrial life.

  9. Height above mean sea level - Wikipedia

    en.wikipedia.org/wiki/Height_above_mean_sea_level

    Elevation or altitude above sea level is a standard measurement for: Geographic locations such as towns, mountains and other landmarks. The top of buildings and other structures. Mining infrastructure, particularly underground. Flying objects such as airplanes or helicopters below a Transition Altitude defined by local regulations. [2]
