Explain the difference between weather and climate.
Think about today compared with many years of seasons in one place.
Weather is the condition of the air outside at a certain time and place, such as rainy, sunny, windy, or cold. Climate is the usual pattern of weather in a place over many years. - 2
A city has warm, rainy summers and cool, dry winters every year. Is this a description of weather or climate? Explain your answer.
This is a description of climate because it tells the usual weather pattern in that city over many years, not just the conditions on one day. - 3
On Monday it is 72 degrees Fahrenheit and sunny. On Tuesday it is 60 degrees Fahrenheit and rainy. What changed from Monday to Tuesday?
Look for changes in temperature and precipitation.
The weather changed from Monday to Tuesday. The temperature dropped, and the sky and precipitation changed from sunny to rainy. - 4
Name two kinds of precipitation and describe each one.
Two kinds of precipitation are rain and snow. Rain is liquid water that falls from clouds, and snow is frozen ice crystals that fall when the air is cold enough. - 5
A student records the weather for 7 days and finds that 5 days were cloudy and cool. What does this pattern suggest about that week?
A week is a short amount of time.
This pattern suggests that the week had mostly cloudy and cool weather. It shows a short-term weather pattern for those 7 days. - 6
Why do people use thermometers when studying weather?
People use thermometers to measure air temperature. Temperature helps describe daily weather and lets people compare warmer and cooler days. - 7
What does a rain gauge measure, and why is that useful?
It collects falling rain so it can be measured.
A rain gauge measures how much precipitation, usually rain, has fallen. That is useful because it helps people track weather patterns and understand how wet or dry an area is. - 8
If a place is very dry and gets little rain year after year, what can you say about its climate?
Its climate is dry because it gets very little precipitation over many years. A long-term pattern of low rainfall is part of the place's climate. - 9
Describe how wind can affect weather on a given day.
Moving air can carry clouds and different temperatures.
Wind can move air masses and clouds from one place to another. This can make a day feel cooler or warmer and can bring changes such as clouds, rain, or clearer skies. - 10
A coastal town usually has cooler summers and warmer winters than a desert inland area. What is one reason these climates may be different?
One reason is that large bodies of water heat and cool more slowly than land. The nearby ocean can make temperatures in the coastal town less extreme than in the inland desert area. - 11
What is one sign that spring weather is beginning in many places?
Think about how the air and plants change after winter.
One sign of spring is that temperatures begin to warm and rain becomes more common in many places. Plants may also start to grow again as the season changes. - 12
Why is it important to record weather over a long time when studying climate?
It is important because climate is based on long-term patterns, not one day or one week. Recording weather over many years helps scientists see what conditions are usual in a place. - 13
A forecast says a cold front is moving in. Predict one possible change in the weather.
A cold front brings cooler air.
One possible change is that the temperature may drop as cooler air moves into the area. Clouds, wind, or rain may also increase. - 14
Compare a tropical climate and a polar climate.
A tropical climate is usually warm all year and often gets a lot of rain. A polar climate is very cold for most or all of the year and often has ice and snow. - 15
A student says, "It snowed today, so this place must have a snowy climate." Explain why that statement may not be correct.
One event does not show a long-term pattern.
That statement may not be correct because one snowy day describes weather, not climate. Climate depends on the usual weather patterns in a place over many years, so one day is not enough evidence.
