SCIENCE WATER 2(November) Flashcards
Slope of a stream channel expressed as the vertical drop of stream over a specified distance
Gradient
The shape, size and roughness of the channel affect the amount of friction
Channel Characteristic
Volume of water flowing past a certain point in a given unit of time
Discharge
The other body of water’s steep fall over a rocky ledge into a plunge pool below
Waterfall
There’s a great volume of water
Cataracts
If there’s a small volume of water
Cascade
-Entire river system
-an area drained by a river and it’s tributaries
-also called as “drainage basin”
Watershed
Collected in the space between sediments and the cracks within the rock
Ground water
Portions of the lithosphere in which the pore spaces are filled with water
Zone of saturation
It is an underground boundary between the soil surface and the area
Water table
Water soaks into the ground
Porosity
It contains countless voids or openings called___
Pore spaces
It is the percentage of the total volume of rock or sediments that consists of pore spaces
Porosity
Ability of a material to transmit fluids
Permeability
Ground water moves by twisting or turning
Permeability
The smaller the pore spaces, the slower it moves
Permeability
Permeable later or sendiments that transmit
Aquifers
Impermeable layers that hinder or prevent water movement like clay
Aquitards
It has a high porosity but poor permeability due to very small pores opening
Clay
A hole in the ground that forms when water dissolves the surface rock
Sinkhole
Body of water that is surrounded by land
Lake
Continuous rainfall will cause too much depression and stress in the land area
Lake
It can be man-made or natural-made
Lake
Common lake in the Philippines
Taal lake
Lanao lake
