Flashcards in Chapter 6 Deck (19):
An approaching cold front produces rapidly moving, towering clouds.
results from zillions of tiny molecules of gases (mostly nitrogen and oxygen) in the atmosphere zipping around at incredible speeds and hitting and bouncing off anything they encounter.
When the temperature drops below a certain level where condensation takes place, moisture in the air condenses and forms clouds.
major surface winds that blow almost continually and distribute air and moisture over the earth's surface.
Movement of nutrient-rich bottom water to the ocean;s surface. This can occur far from shore but usually occurs along certain steep costal areas where the surface layer of ocean water is pushed away from the shore and replaced by cold, nutrient-rich bottom water.
El Nino-Southern Oscillation (ENSO)
Every few years in the Pacific Ocean, normal shore upwellings are affected by changes in climate patterns.
Distance from the equator
Height above sea level.
is dominated by thorn tress and shrubs adapted to long dry spells followed by brief, sometimes heavy rain. between deserts and grasslands.
Closeness to the sea provides a slightly longer winter rainy season than nearby temperate deserts have, and fogs during the spring and fall evaporation.
Plants, such as desert cacti, that survive in dry climates by having no leaves, thus reducing the loss of scarce water, They store water and use sunlight to produce the food they need in the thick, fleshy tissue of their green stems and branches.
Perennially frozen layer of soil pores that forms when the water there freezes. It is found in arctic tundra.
occurs above the limit of tree growth but below the permeant snow line high mountains. Vegetation is similar to that found in arctic tundra, but it gets more sunlight that arctic vegetation and has no permafrost layer.
air plants, such as some types orchids and other plants.
Site planted with one or only a few tree species in an even aged stand. When the stand matures it is usually harvested by clear-cutting and then replanted. These farms normally are used to grow rapidly goring tree species for fuelwood, timber, or pulpwood.
coniferous evergreen trees
Cone-bearing plants (such as spruces, pines, and firs) that keep some of their narrow, pointed leaves (needles) all year.
costal coniferous forests
aka temperate rain forests, found in scattered costal temperate areas with ample rainfall or moisture from dense ocean fogs.
during the summer the soil becomes waterlogged forming acidic bogs, in plow-lying areas of these forests.
