• Paintings

• Shapes of clouds and color of the sky

• Recipes

According to the passage, how accurate are meteorologists' forecasts today?

• Never right

• Sometimes right

• Always right

• Mostly right

What does weather describe?

• The temperature of the ocean

• What is happening in the atmosphere at one place during a particular time

• How much water there is

(a)   form ​ when air rises and the water vapor cools. When ​ (b)   rises, the air pressure changes.​

• Clouds
• Wind
• Temperature
• air
• temperature
• a cloud

Why do forecasters need to know the direction and speed of the wind?

• To predict the temperature

• To predict what weather will reach an area and when

• To determine the number of clouds

• To measure air pressure

What happens in a high-pressure area?

• More air over a location, creating more weight

• Less air over a location, creating less weight

• More air over a location, creating less weight

• Less air over a location, creating more weight

What happens when cold air meets warm air in a low-pressure area?

• They mix in a straight line

• They move away from each other

• They mix in a circular motion

• They create clear skies
