The process where water tears away at soil, rock, and other solid materials at its edges and carries solids away.

What is erosion.

200
The process by boiling water to create water vapor that is "caught" and condensed back into liquid water.
What is distillation
200
What percent of the earths water is saltwater?
What is 97%
200
This should not be present in any drinking water.
What is bacteria or toxins.

As this land form becomes bigger they begin to slide and carve out the land into valleys and other shapes.

What is glacier.

200

Where do alpine glaciers form?

On mountains (they then move downward towards valleys)

300
Liquid water changes to a gas and becomes water vapor.
What is evaporation

Why is saltwater not safe for humans and animals to drink?

Our cells cannot process that much salt & all the water in our body will go towards processing the salt (hypernatremia)

300

Fast flowing rivers increase this type of land change...

What is erosion.

What is causing glaciers to melt
What is global warming
300

What are the two main types of glaciers?

Ice sheets and alpine glaciers
400
The movement of molecules from one area of high concentration to an area of low concentration.
What is reverse osmosis
400

The movement of surface water caused by wind and sometimes machines on the water.

What is wave.

Name 2 consequences to melting glaciers

Less freshwater for animals, rising sea levels, changing weather on land

500
Name one of the things water is tested for to ensure it is potable.
What is taste, odour, color, toxicity, bacteria, mineral content, pH level
500

The regular rise and fall of a large body of water (like a ocean) caused by the gravitational pull of the Moon and the Sun.

What is tide.

500
Name one negative impact humans have on water supply.
What is fertilizer running into rivers, oil spills, sewage, etc.
500
True or False: Glaciers are so thick the ice never melts.
What is False. The bottom layer on ice melts causing the glacier to move. Glaciers are also melting due to global warming.
