1. what is the water cycle 
2. what are the steps for the water cycle
3. why is the water cycle important 

What is the Water Cycle

The water cycle describes how water moves between Earth's surface and the atmosphere.

Water moves through processes like evaporation, condensation,  precipitation and collection.

Stages of the Water Cycle

Evaporation:

 Water from oceans, rivers, and lakes turns into water vapor and rises into the air.

Condensation: 

Water vapor cools and forms clouds.

Stages of the Water Cycle

Precipitation: 

Water falls back to Earth as rain, snow, or hail.

Collection:

 Water collects in rivers, lakes, and oceans, that's where the cycle begins again.

Evaporation

The process where water changes from liquid to gas (water vapor) due to heat from the sun.

Evaporation happens from bodies of water, soil, and even plants (this process is called transpiration).

Condensation

As water vapor rises and cools, it forms tiny droplets that make up clouds.

Condensation happens when warm, moist air meets cooler air.

Precipitation 

Precipitation occurs when the water droplets in clouds get too heavy to stay in the air and fall to Earth.

Types of precipitation: rain, snow, sleet, or hail.

Collection

Once water falls as precipitation, it collects in rivers, lakes, oceans, or it can infiltrate into the ground.

Water in rivers eventually flows back to the ocean, where the cycle starts again.

Why is the water cycle important

It maintains the Earth's water supply.

It supports plant and animal life.

It regulates weather patterns and helps prevent droughts.

Fun fact about the water cycle

The Earth’s water supply is constantly recycled through the water cycle.

The water you drink might have been part of a raindrop millions of years ago!

Some of the water in the cycle has been on Earth for billions of years.

What is the first stage of the water cycle

1. precipitation
2. evaporation
3. condensation
4. collection

what happens during evaporation

1. water vapor cools down and forms clouds
2. water falls to the ground as rain or snow
3. water changes from liquid to gas due to the sun's heat
4. water is collected in rivers, lakes, and ocean

What is condensation

1. water turning into vapor and rising into the air.
2. water vapor cooling and forming clouds..
3. water falling to earth as rain, snow, or hail.
4. water collecting in oceans, lakes, and rivers.

which of the following is NOT a type of precipitation

1. rain
2. snow
3. cloud
4. hail
