Climate- Weather-Water cycles

What is weather? 

It is what the air and sky are like

each day. 

How can weather change? 

Weather changes from day to day.

Temperature is how cold or warm

the air is. Sometimes the air feels

cold. Sometimes the air feels warm.

The sky can change too.

Some days the sky is clear.

Some days the sky is full of clouds

How can you learn more

about the weather? 

Scientists use tools to measure

weather just like you. They use

the information they collect to

make weather reports.

You can read weather reports in the

newspaper. You can watch weather

reports on television. You can even

find weather reports on the computer

Multiple Select

When you describe how hot or cold the air is, you are talking about____________________

• weather

• temperature

• pressure

• climate

Multiple Select

How do we know what the weather will be like tomorrow?

• We phone the weather.

• We send email to the weather.

• We make a weather prediction.

Multiple Choice

Choose the correct weather map according to the description.

This is the weather in Spain today. In the north it’s very cloudy and rainy. IN the south, east and center it’s sunny.

Multiple Choice

This is the weather in Spain today. In the north it’s...............................and the south is................

• dry- hot

• hot-hot

• sunny-dry

What causes severe weather? 

You may wake up to a warm, sunny day.

However, as hours go by, the temperature may

drop. Puffy clouds appear in the western sky.

They soon are overhead and grow tall.

Why does weather change? Weather is

affected by air masses that move across

your area. An air mass is a large amount of

air that has similar temperature and humidity

throughout. For example, an air mass may form over warm ocean water. The air mass will be warm and humid. Another air mass may form over cold land. It will be cool and dry

Multiple Choice

Air mass changes the weather.

• True

• False

Multiple Choice

Air mass is different in different locations.

• True

• False

Multiple Select

Take a look at the globe map, and tell.

Where does the cold air mass come from

• North pole

• South pole

• Equator

• Ocean

Fronts 

Weather changes when one air mass moves into another air mass. The meeting place between two air masses is called a front.

Warm Fronts A warm air mass moves over a cold air mass. Cirrus clouds form higher up and then stratus clouds form closer to the ground. There may be some light, steady rain or snow.

Cold Fronts A cold air mass moves under a warm air mass. Warm air is pushed up along the

front. Towering clouds may form and storms may break out.

Multiple Choice

What is weather 's front?

• The meeting of 2 air masses .

• The movements of two air masses.

• The changing of air masses.

Multiple Choice

steady rain or snow.

Weather Maps

A weather map shows the

weather in a given area at one

time. For each city or town, a

weather map lists such

information as:

• air temperature

• wind speed and direction

• cloud cover.

With this information each

day for a week, you can forecast

the next day’s weather. 

How can scientists forecast  tomorrow’s

weather? To forecast means to “make a guess about what will happen based on what you know and see.”

For example, if you see something

happen day after day, you may

forecast that it will happen tomorrow.

Scientists use what they know

and see to forecast

the next day’s weather. They know air pressure, wind speed and direction, air temperature, kinds of clouds, and so on.

 

Multiple Select

By calculating the air pressure, wind speed and direction, air temperature, kinds of clouds, and so on, scientists can inform us what the weather is going to be.

• True

• False

What is climate?

Climate is the long-term average of

weather, typically averaged

over a period of 30 years.

More rigorously, it denotes

the mean and variability of

meteorological variables

over a time spanning from months to millions of years.

Climate maps give you information about the

climate (weather) and precipitation (rain and

snow).

Water on Earth is never lost. Water keeps changing

from solid to liquid to gas and then back to liquid and

solid. It keeps moving from Earth’s surface to the sky

and then back to Earth. The continuous movement of

water between Earth’s surface and the sky as it changes

form is called the water cycle.

Multiple Choice

• continuous movement

• continues change of states of the water

Air pressure can change during any day. For example, air pressure changes when air temperature changes. Tools called barometers are used to measure air pressure and tell how it changes.

A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed.

A rain gauge is a tube that collects water. It shows the amount of rainfall.

A thermometer measures air temperature in degrees.

A wind vane points in the direction from which the wind is blowing.

An anemometer measures wind speed. The faster the wind blows, the faster the cups spin.

A partial solar eclipse occurs more often than a total solar eclipse because for a total solar eclipse to occur, Earth, the Moon, and the Sun must line up exactly in a straight line to totally block the Sun. More often their alignment is not exactly in a straight line, which creates a partial solar eclipse.
