what is potable water
Why is water rarely ever pure?

large moving bodies of ice.
what are glaciers
what are tides caused by?
the gravitational pull of the moon
Explain the difference between a sea mount and a volcanic island
seamount is when the underwater volcano does not go above the water's surface. When a seamount rises above the surface due to volcanic activity, it is called a volcanic island.
the water is containing high concentration of calcium and magnesium.
what is hard water
what is turbidity?
how cloudy the water is
Small hills with a distinctive teardrop shape.
what are drumlins
The highest part of the wave is called the _______________.
crest
meandering means?
a river bending or curving due to sediments being deposited
how salty the water is.
what is salinity
name 5 things we test water for

Small lakes that come from the melt off of the Glaciers
what are kettle lakes
The bottom part of the wave is called
trough.
Which of the following represents the percentage of the world's water that is freshwater?
3%
What is water's distribution on Earth?
3% of the worlds water is fresh with the other 97% being saltwater. Of the 3% of fresh water that is on earth 77% is frozen 22% is in the ground and 1% is in lakes and rivers
How does distillation work? What is used for?

what is a esker
at what point is a river very fast and deposits very little sediment?
at the beginning of a glacier when it is moving down a mountain
explain how large bodies of water affect climate
Large bodies of water put off a lot more condensation into the air so it greatly increases that water that falls in those areas. water can also hold onto heat longer than air so when air cools at night, water will release heat making the surrounding area warmer.
what is a watershed and What determines the direction of the watershed?
Watershed is an area of land that drains into one main river . The highest land called continental divide determines the direction that the watershed drains
How does reverse osmosis work?
Reverse osmosis is a water purification process that uses a semi-permeable membrane (synthetic lining) to filter out unwanted molecules and large particles such as contaminants and sediments like chlorine, salt, and dirt from drinking water.
parallel ridges of debris deposited along the sides of a glacier.
what are moraines
what is a delta
a fan shape deposit of sediments created when a stream or river feeds into a ocean or large lake
What causes trenches to form on the ocean floor
Ocean trenches are a result of tectonic activity, which describes the movement of the Earth's lithosphere. In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet
