Keywords

💡Water Cycle

The water cycle is a continuous process through which water moves across the Earth's surface and through the atmosphere, changing its state from liquid to vapor and back again. It is central to the video's theme as it illustrates how water is constantly in motion and transformation, affecting ecosystems and climate. The script mentions the water cycle as the path that all water follows as it moves around the Earth in different states or phases.

💡Evaporation

Evaporation is the process by which water changes from a liquid state to a gaseous state, such as when the sun heats up bodies of water, causing them to turn into water vapor. This concept is foundational to understanding the water cycle, as it is the first stage where water moves from the Earth's surface into the atmosphere. The script describes evaporation as a key stage where the sun heats waters in oceans, lakes, rivers, and other bodies of water, turning it into a gas that evaporates into the air.

💡Transpiration

Transpiration is the process by which plants release water vapor into the atmosphere through their leaves. It is similar to evaporation but occurs in plants. The script emphasizes transpiration as a vital part of the water cycle, highlighting how plants contribute to the water vapor in the air, which is then available for the next stages of the cycle.

💡Condensation

Condensation is the process where water vapor in the air turns back into liquid, typically when it cools down, forming clouds. This keyword is crucial for understanding the water cycle's transformation of water from gas to liquid. The script uses the example of looking at a bathroom mirror after a hot shower to observe condensation, illustrating how water vapor turns into liquid droplets.

💡Precipitation

Precipitation refers to any form of water that falls from the sky, including rain, snow, sleet, or hail. It is a critical stage in the water cycle where water returns to the Earth's surface.

the water cycle

believe it or not but the water you

drink today

may actually be millions of years old

this is because the water on earth has

existed since the beginning of time and

is constantly moving and changing phases

this happens through a process called

the water cycle

today we are going to learn all about

the water cycle and how it works so that

we can protect our water and make sure

there is plenty for future generations

what is the water cycle before we get

into the details about this cool process

we need to know what it means

so

what is the water cycle

it is the path that all water follows as

it moves around the earth in different

states or phases

water in its liquid phase is found in

oceans

rivers

lakes

and even underground

solid water or

ice

is found in glaciers

snow

and at the north and south poles

water vapor is a gas and it is found in

the earth's atmosphere

water cycle stages

how does this process happen

it happens

through four different stages called

evaporation transpiration

condensation

and

precipitation

let's talk about each in more detail

shall we

first up

evaporation

evaporation happens when the sun heats

up the waters in oceans lakes rivers and

other bodies of water

when the water gets hot enough

it changes into a gas

this gas

then evaporates into the air

you can see this process for yourself if

you leave an open container of water in

your home

or outside

once it gets hot enough

it will evaporate

next up

transpiration

transpiration is the process by which

plants lose water in the form of water

vapor

basically it is the release of water

through a plant's leaves

and is similar to evaporation because

that water vapor goes into the air

condensation

condensation occurs when the water vapor

in the air becomes cold and changes back

into a liquid

this is how clouds are formed

can you guess what happens when there is

too much moisture in a cloud

it rains

and if you want to see condensation as

it is happening

look at your bathroom mirror after you

have taken a hot shower

you will see lots of condensation

finally

precipitation

precipitation is rain

snow

sleet

or hail

that falls to the ground and it happens

when the air can no longer hold the

water that has been evaporated

as we mentioned before when clouds get

too heavy it rains

and the evaporated water makes its way

back down to the earth

this precipitation will gather in bodies

of water or underground

and the whole water cycle starts again

since we have a limited amount of water

on our planet

it is important to take care of it

here is an interesting fact

the water cycle is critical to

maintaining and determining the earth's

temperature without it the earth

temperature becomes extremely hot

or extremely cold which has a huge

impact on both plant

and animal life

knowing how the water cycle works and

how humans can protect it is very

important to the future survival of the

planet

so how can you help

well

one of the best things you can do is to

conserve water whenever you can

whether that means turning off the

faucet when you're brushing your teeth

or taking a shorter shower

every little bit helps

you can also talk to your parents about

watering your lawn less during hotter

months

another way to protect the water is to

keep it clean

which means

no littering

especially in your local lakes rivers

and streams

here is another fact

the fresh water on earth makes up about

three percent of all the earth's water

and only about 0.3 percent of all fresh

water is visible research by scientists

reports that the atmosphere surrounding

the earth contains more fresh water than

all the rivers combined

so

it is important to conserve fresh water

whenever we can

now that we have learned about the water

cycle let's go ahead and review some

facts name two stages of the water cycle

evaporation

transpiration

condensation

precipitation

true or false

the water cycle helps maintain the

earth's temperature

that is true

fill in the blank

only blank percent of all water on earth

is fresh water

did you remember it was three percent

nice work water warriors

whether you see it in the ground or feel

it in the air

water is everywhere

and now that you know about the

importance of the water cycle you can

see the stages happening all around you

the next time it rains

or the next time you see a foggy window

or mirror you can remember everything

you learned about the water cycle
