Fichas del conjunto (37)
- 1AtmosphereThe gaseous envelope surrounding Earth
- 2Coriolis EffectThe tendency of moving air or water to be deflected from its path and swerve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is due to the rotation of the earth.
- 3Prevailing WindsMajor surface winds that blow more or less continually.
- 4RunoffThe movement of fresh water from precipitation and snowmelt to rivers, lakes, wetlands, and the ocean.
- 5GroundwaterThe supply of fresh water under Earth's surface that is stored in underground aquifers.
- 6Saltwater IntrusionThe movement of seawater into a freshwater aquifer near the coast
- 7GyresLarge, circular ocean current systems that often encompass an entire ocean basin.
- 8El Niño–Southern Oscillation (ENSO)A periodic, large-scale warming of surface waters of the tropical eastern Pacific Ocean that temporarily alters both ocean and atmospheric circulation patterns.
- 9La NiñaOccurs when the surface water temperature in the eastern Pacific Ocean becomes unusually cool and westbound trade winds become unusually strong.
- 10Intertidal ZoneThe area of shoreline between low and high tides.
- 11Neritic ProvinceThe part of the pelagic environment that overlies the ocean floor from the shoreline to a depth of 200 m (650 ft).
- 12Oceanic ProvinceThe part of the pelagic environment that overlies the ocean floor at depths greater than 200 m (650 ft).
- 13Benthic EnvironmentThe ocean floor, which extends from the intertidal zone to the deep ocean trenches.
- 14Plate TectonicsThe study of the processes by which the lithospheric plates move over the asthenosphere.
- 15BiosphereThe layer of Earth that contains all living organisms.
- 16CommunityA natural association that consists of all the populations of different species that live and interact together within an area at the same time.
- 17EcosystemA community and its physical environment.
- 18LandscapeA region that includes several interacting ecosystems.
- 19PopulationA group of organisms of the same species that live together in the same area at the same time.
- 20BiomeA large, relatively distinct terrestrial region with similar climate, soil, plants, and animals regardless of where it occurs in the world.
- 21Boreal ForestA region of coniferous forest (such as pine, spruce, and fir) in the Northern Hemisphere; located just south of the tundra. Also called taiga.
- 22ChaparralA biome with mild, moist winters and hot, dry summers; vegetation is typically small-leafed evergreen shrubs and small trees.
- 23DesertA biome in which the lack of precipitation limits plant growth; deserts are found in both temperate and tropical regions.
- 24Ecosystem ServicesImportant environmental benefits, such as clean air to breathe, clean water to drink, and fertile soil in which to grow crops, that the natural environment provides.
- 25EstuaryA coastal body of water, partly surrounded by land, with access to the open ocean and a large supply of fresh water from a river.
- 26Flowing-Water EcosystemsA freshwater ecosystem such as a river or stream in which water flows in a current.
- 27Freshwater WetlandsLands that shallow fresh water covers for at least part of the year; wetlands have a characteristic soil and water-tolerant vegetation.
- 28SavannahA tropical grassland with widely scattered trees or clumps of trees.
- 29Standing-Water EcosystemsA body of fresh water surrounded by land and whose water does not flow; a lake or a pond.
- 30Temperate Deciduous ForestA forest biome that occurs in temperate areas where annual precipitation ranges from about 75 cm to 126 cm (30 to 50 in).
- 31Temperate GrasslandA grassland with hot summers, cold winters, and less rainfall than is found in the temperate deciduous forest biome.
- 32Temperate Rain ForestA coniferous biome with cool weather, dense fog, and high precipitation.
- 33Tropical Rain ForestA lush, species-rich forest biome that occurs where the climate is warm and moist throughout the year.
- 34TundraThe treeless biome in the far north that consists of boggy plains covered by lichens and mosses; it has harsh, cold winters and extremely short summers
- 35Ecological SuccessionThe process of community development over time, which involves species in one stage being replaced by different species
- 36EvolutionThe cumulative genetic changes in populations that occur during successive
- 37Natural SelectionThe tendency of better-adapted individuals—those with a combination of genetic traits best suited to environmental conditions—to survive and reproduce, increasing their proportion in the population.
