Chapter 2.5 Flashcards
This is a very large body of water that dominates the Earth’s surface. ——-
Ocean
In what percent does the ocean cover the Earth’s surface? ——
70%
What are the five major oceans in the world? ——-
Atlantic ocean, pacific ocean, indian ocean, southern ocean, and arctic ocean
The five major oceans branch off into some of the major seas. What are these? ——
Mediterranean Sea, South China Sea, and Caribbean Sea
T|F: Continental slope is the submerged margins of the continent that stretch seaward from the extreme low-tide mark to depths of approximately 600ft below sea level ——-
False, continental shelf
At which point the sea bed drops precipitously to the sea floor? ——
Continental slope
What are the highly productive communities in the continental shelf? ——
Seagrass meadows, kelp forests, coral reefs, upwelling systems, and fishing banks
What are biomes that occur where a river, a source of fresh water, meets the ocean? —–
Estuaries
T|F: In estuaries, both fresh water and salt water are found in the same vicinity; mixing results in a diluted/brackish salt water. ——
True
What does lentus mean? ——
slow or motionless
What is included in lentic ecosystems? —–
Ditches, seeps, ponds, seasonal ponds, basin and lakes
In the freshwater biome, what is strongly influenced by water chemistry, particularly its transparency and nutrient concentration? ——-
Lentic ecosystem
What is the term that describes water bodies that are rich in nutrients, particularly nitrogen and phosphorus. These nutrients promote the growth of algae and other aquatic plants? ——-
Eutrophic
What is the term that describes water bodies that are low in nutrients and therefore have lower productivity. These waters are typically clear, with few algae and higher oxygen levels? ——-
Oligotrophic
Define the aquatic environments with flowing water, such as rivers, streams, and creeks. ——
Lotic ecosystems
T|F: Lotic ecosystems rarely display the vertical stratification patterns found in standing bodies of water because of their tranquil flow. ——
False, turbulent
Large, slow, meandering, soft-bottomed streams. ——
Rivers
What is the longest river in the world ranging 6,650 km? ——
Nile river
In which country does the Nile river be located? ——
Africa
T|F: Rivers do not play a huge role in the water cycle. —–
False
What is the second longest river in the world ranging 6,400 km and in which country? ——
Amazon in South America
Name one river in the Philippines. ——
Cagayan (505 km),
Rio Grande de Mindanao (373 km),
Agusan (349 km)
What is the third longest river? —–
Yangtze with 6300 km
What is the sixth longest river? ——
Yellow River with 5464 km
What is the 12th longest river? ——–
Mekong with 4350 km
This is an area of land that drains or “sheds” water into a specific waterbody. ——
watershed
T|F: Wetlands are drained by a stream and all of its tributaries which flow into larger ones, including lakes, bays, and oceans. —–
False, watershed
T|F: Watershed includes swamps, marshes, bogs, and fens. ——-
False, wetlands
This is an ecosystem that is flooded by water, either permanently or seasonally with characteristic vegetation of aquatic plants, adapted to the unique hydric soil driven by frequently occurring prolonged inundation and/or soil saturation (waterlogging). ——
Wetlands
What is a transitional habitat that is part land and part water? ——
ecotones
Wetlands lie between dry land and deep water is also referred to as ——
ecotones
Any wetland dominated by woody plants ——
swamps
This serves vital roles in flood protection and nutrient removal. ——-
swamps
What is especially high in productivity and species diversity because of the rich deposits of alluvial soil from floods? —–
floodplains
