Chapter 3: Water and its spatial distribution Flashcards
What are the physical states of water?
Solid, liquid, gas
Where is water found?
Oceans, glaciers, lakes, rivers, groundwater, soils
What is the term for raining called
Precipitation
What are the outputs of water?
Discharge into sea
Evaporation
Transpiration
Are water stores evenly distributed on the earth’s surface?
No.
What is the term for e.g. glaciers may melt and flow into rivers, which eventually flows into oceans?
Those movements are called flows.
Water can move from one store to another.
Do oceans have low amounts of salt content?
No, they have high amounts of salt content. The other water stores contain freshwater, which means that they contain water with low amounts of salt content.
What are the 4 national taps?
Desalination
NEWater
Imported water
Water from local catchment
What are rivers?
Rivers are natural wide flows of freshwater across the land that store water temporarily before water flows into another water body.
What are the 5 oceans?
Indian Ocean, Arctic Ocean, Pacific Ocean, Southern Ocean, and Atlantic Ocean
How does soil store water?
When it rains, water passes through the soil through very small openings known as pores. Water that is stored in the soil is known as soil moisture.
What is groundwater?
Groundwater is found below the surface of the earth. Water enters the ground through pores in the soil due to gravity.
It is also water that seeps into the ground may be absorbed by plants or stored as groundwater.
How does ground water form?
When a part of water make its way to the rocks beneath, filling up the pores and cracks of these rocks.
Hydrological cycle process
- Precipitation
- Groundwater
- Surface run off
- Evaporation
- Transpiration
- Condensation
What is precipitation?
Water falls as rain, or snow if the air is cold enough.
