100

Saltwater is not potable do to the salt content, also known as this

Salinity

100

True/false. The particles in a wave do not end up moving sideways

False. They do, but slowly

100

Winding deposits of rock material from glaciers

Eskers 

100

Water that looks and smells good should not be trusted because it could complain this. While invisible it will likely cause digestive problems (or worse)

Bacteria, toxins

100

When hot/cold water is released into the environment, changing the temperature of the ecosystem

Thermal pollution 

200

This is the main cause of tides

Moon's gravitational pull

200

Paper production is a (direct/indirect) use of water

indirect

200

Due to the height of rocky mountains, it is dry on this side

East

200

A test or experiment that gets the same result no matter how many times you do it would be called this

Reliable test

200

Other than science and technology, what is needed to solve a problem?

Commitment from people/a want to fix it

300

There is high diversity in these areas of the ocean

Coral Reefs

300

Smooth, consistent waves are called this 

Swells

300

The wall of sediment built up by a glacier pushing on it as it advances is called this

Moraine 

300

Algal Bloom is often caused by this (often from crops)

Fertilizer run off

300

Overhunting, especially of top tier consumers, would be an example of this type of change 

Long-Term

400

Rainforests are warm and moist, which would indicate that the nearby ocean currents are coming from here

The equator 

400

This type of water does not allow soap to lather well and is full of minerals

Hard water

400

When two plates are moving away from each other in the ocean, this gap between the plates is called this

Mid-ocean ridge

400
On the pH scale, pure water would be measured as being this number

7

400

Using a filter to produce pure water would be using this process

Reverse Osmosis

500

About what percentage of water on earth is saltwater

97%

500

When rock breaks down due to a reaction of the minerals in water

Chemical Weathering 

500

The fan shaped marsh where a river meets a lake

Delta

500

This causes water to look brown and cloudy 

Silt

500

Boiling water and passing the vapours through a condenser is this type of water purification 

Distillation
