Earth's Water
Advanced World Geography
| Question | Answer |
|---|---|
| Pacific, Atlantic, Indian, Arctic, Southern | The five oceans |
| Water becomes vapor | Evaporation |
| Moisture released from trees and plants | Transpiration |
| Water vapor becomes clouds | Condensation |
| Clouds become heavy and release rain, sleet, snow, or hail | Precipitation |
| The study of seas and oceans | Oceanography |
| Scientists who study the physical, chemical and biological characteristics of the seas and oceans | Oceanographers |
| Using sound to measure depth or to find objects in the water; so(und) na(vigation) and r(anging) | Sonar |
| What is one reason oceanographers use sonar? | They can map parts of the ocean floor that are too dark to see |
| Gently sloping edge of a continent covered by water; extends to the continental slope; mad of same rock as continent | Continental shelf |
| A steep slope on the ocean floor b/w continental shelf and the continental rise | Continental slope |
| a gentle slope on the ocean made of sediment; located b/w the steep continental slope and flat abyssal plain | Continental rise |
| the region of the ocean floor b/w the coast and the sudden drop-off to the deep ocean floor; includes the continental shelf, rise and slope | Continental margin |
| beyond continental margin, the somewhat flat area of the ocean floor containing abyssal plain, mid-ocean ridge, trenches, seamounts, underwater volcanoes | Ocean basin |
| flat plains on the ocean floor | Abyssal plains |
| underwater volcanic mountain chain | Mid-ocean ridge |
| deep, narrow ocean valleys | Trenches |
| begins as a seamount, then rises above ocean as melted rock accmulates | Volcanic island |
| a valley in the mid-ocean ridge | Rift valley |
| a mountain below the waves | Seamount |
| a flat seamount | Guyot |
| fountains of very hot water that spew from cracks or rifts in the ocean floor, heated by magma | Thermal vents |
| temperature decreases, pressure increases, and light decreased as... | Depth of the ocean increases |
| Sunlight zone Twilight zone Midnight zone | Three zones of the ocean |
| Euphotic zone (contains 90% of all marine life) | Sunlight zone |
| disphotic zone | Twilight zone |
| aphotic zone, no light, high pressure, freezing temperatures | Midnight zone |
| What is the most abundant form of life on eart | Plankton |
| What are plankton so important to us? | They supply 75% of the oxygen we breathe and plankton that have been compressed at the floor of the ocean for millions of years form oil |
| movement of water from the oceans to the air, to the ground, and finally back to the oceans | Hydrologic Cycle |
| drives the hydrologic cycle | Sun |
| area near the surface where groundwater and air collect in gaps in the soil | Zone of aeration |
| zone where all gaps in the soil and rock fill with water | Zone of saturation |
| area b/w the zone of aeration and the zone of saturation | Water table |
| existence of impure, unclean or poisonous substances in the environment | Pollution |
| polluted rain or snow caused by burning fossil fuel | Acid rain |
| deepest spot in the ocean; located in the Mariana Trench | Challenger Deep |
| How does air temperature relate to moisture? | Warm, less dense air holds more water vapor; as air cools is drops the water |
| What forms as a result of condensation? | Clouds |
| The total volume of water in the hydrologic cycle remains... | Constant |
| What happens to half of the waste products produced in the US? And How does this lead to pollution of the water supply? | Half of the waste is dumped into water bodies and becomes part of the hydrologic cycle |
| Agricultural runoff, carbon waste, nuclear waste, industrial waste | Forms of pollution that affect the water cycle |
