Unit 1-fresh And Salt Water Sistems Flashcards
What form can water be found?
Liquid,Solid,Gas
What are the steps of the water cycle?
Evaporation Condensation Precipitation Transportation Run off
What is potable water?
Water that is suitable for humans to drink.
What is Desalination?
When you take water with to much salt and make it suitable for humans to drink
What is eutrophication?
When a body of water has to much nutrients to be healthy.
How do we measure water quality
PH Temperature Turbidity Dissolved Oxygen Phosphates Nitrates
What is a bioindicator?
A bioindicator is living things that tells us the status of a ecosystem
What are some examples of invertebrates that indicate good water quality?
Mayflies
Caddisflies
Stoneflies
What is the difference between the ice caps in the North Pole and the South Pole
North Pole: salt ice sheet floating on the ocean
South Pole: fresh water ice on top of land
How will warming temperatures effect both the poles differently?
The ocean absorbs more sun than land so the ocean melts the ice of the North Pole faster than the South Pole.
What role does the poles play in keeping the temperature on Earth cooler
The ice reflects most of the Suns rays so it keeps the Earth cool but if they weren’t there the Earth would absorb all the Rays making it much hotter
How are glaciers formed
The snow eventually piles up and the pressure of the snow on top makes the bottom turn to ice.
What is a Moraine?
Moraines are made from rubble left behind by glaciers.
What are the three types of moraines
Terminal moraine
Lateral Moraine
Medial Moraine
What is a drumlin
An oval mound or small hill of rock that was made by past glacial action
What is a Esker
A long ridge of sediment and gravel that usually has a winding course caused by a retreating glacier
What is a erratic
A rock or Boulder that is thought to have been brought from a distance by a glacier.
What is a Kame
Is a hill of gravel made by past glacial movement
What is a kettle
A dip in the ground made by a glacier. When water is in it its called a kettle lake.
What are striations
Scratches cut into beadrock by glacial movement
What is a outwash plain
Is a plain formed by glacial sediments deposited by meltwater.
What are Crevasses
Deep cracks in glaciers that are sometimes as deep as the glacier
What is a Arête
An arête is a thin ridge of rock separating a u shaped valley
What is a Horn
A horn is a sharply pointed mountain peak due to multiple glaciers diverging
