Water Cycle

Test

A continuous pattern in nature in which water moves as it changes state above, on, and below the surface of Earth

Water Cycle

The change of state from a solid to a liquid; occurs when a solid gains thermal energy

Melting

The change of state from a solid to a gas without first becoming a liquid; occurs when a solid gains thermal energy

Sublimation

The change of state from a liquid to a gas; occurs when a liquid gains thermal energy

Evaporation

The change of state from a gas to liquid; occurs when a gas loses thermal energy

Condensation

The change of state from a gas to a solid; occurs when a gas loses thermal energy

Deposition

The change of state from a liquid to a solid; occurs when a liquid loses thermal energy

Freezing

Water from a precipitation and snowmelt that flows over Earth’s surface

Runoff

Water that seeps through soil and cracks in rocks, source of water for underground springs and wells

Groundwater

A geological formation of loose rock or soil that is saturated with ground water

Aquifer

The depth at which loose rock and soil below Earth’s surface are saturated with water; the upper boundary of an aquifer

Water table

Solid or liquid water that falls to Earth’s surface

Precipitation

A frozen field of ice covering either the North or South Pole

Polar ice sheet

A large area of ice that permanently covers land

Icecap

A river of ice, formed from snow accumulated over hundreds of years, that moves slowly downhill under the force of gravity

Glacier

The process of removing potentially dangerous substances from water to make it more acceptable for a desired end use.

Water treatment

Sticky clumps formed from the reaction of alum in water, combined with sand and other waste solids.

Floc

Being able to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Sustainability

Describe three characteristics of water at room temperature

Colourless, tasteless, and clear

Name the two kinds of particle that make up a water particle. How many of each kind of particle are found in a water particle?

The two kinds of particle that make up a water particle is oxygen and hydrogen. There is one oxygen particle and is two hydrogen particles.

List the three states of water. Name a place in, on, or above Earth where you would find each state.

The three states of water are solid (ice), liquid (water), and gas (water vapour). A place on earth where you would find solid is in colder places like on mountains, like Whistler. A place on earth where you would find liquid is oceans, like the Pacific ocean. A place above earth where you would find gas is in the air, like the atmosphere.

What is an aquifer? Does water that collects in an aquifer remain there forever? Explain.

An aquifer is FINISH

Describe the role of the Sun in the water cycle.

The role of the Sun in the water cycle is to provide energy to it so it can change from one state to another.

Define the term “sustainability” in your own words. How does your current personal water use
affect sustainability?

Sustainability is being able to meet needs of our earth now without damaging the ability of our future generations to do the same (meet needs of our earth). My own current personal water use affects sustainability because FINISH

As water evaporates from the oceans, what happens to the total amount of water on Earth? Explain. How does this affect living things.

As water evaporates from the oceans, the total amount of water on earth stays the same since it goes in a cycle. Once the water evaporates, it comes back down as rain to the surface to be evaporated again. It affects living things by moving water around. It goes from the ground to the ocean to the clouds and repeats itself. This helps water get to most aspects of life.

Describe one characteristic of water in liquid state. (look at diagram; lesson 1)

One characteristic of water in liquid state is that liquid water vibrates more since it has more space to move around.

Explain the changes of water. (three states)

Solid water is a defined shape. It does not move around freely and just vibrates. Liquid water vibrates faster and is free to move around in all directions. Gas water particles are farther apart so they have more space to move and vibrate more. They have more energy and move quickly in all directions.

Explain how condensation and precipitation are similar and different.

Condensation and precipitation are similar because they are both gas water turning into solid water or liquid water. They are different because ASK CARUSO

Ice forms on the surface of a body of water in winter. Explain why the ice does not sink to the bottom

Ice does not sink to the bottom on lakes because ice is less dense then water.

You dip a container into a small lake in northern Ontario. The water is colourless and has no odour. Would it be safe to drink? Explain

No because water that is colourless, odourless, and tasteless may still contain substances and organisms that make it unsafe to drink.

Not every Canadian has access to treated drinking water. Where might household tap water not
go through a municipal water treatment process? If freshwater resources are to be used sustainably, which of the following do you think will have the greatest impact: building more water treatment plants, using less water, or cleaning wastewater before returning it to the ecosystem? Explain your answer.
