What characterizes an air mass?

Weather changes constantly within

Always cold and dry air

Only found in high altitudes

Same temperature, humidity, and air pressure throughout.

Obavezno

1

What type of weather do low-pressure air masses bring?

Cold temperatures and clear skies

Rainy, wet weather with potential storms.

High humidity and no precipitation

High winds with dry conditions

Obavezno

1

What mainly influences the movement of air masses?

Local temperature changes

Mountain ranges and valleys

Global winds, like jet streams.

Ocean currents and tides

Obavezno

1

How does humidity affect air mass formation?

It causes air mass to rise always

It dries out the air mass completely

It cools down the air mass quickly

It measures water vapor amount in the air.

1

What happens when a cold front meets a warm front?

Cold air stays on the surface.

Cold air slides under warm air, causing precipitation.

Warm air pushes cold air away.

Warm air sinks below cold air.

Obavezno

1

What type of precipitation occurs when warm air rises?

Clouds and precipitation form from humid rising air.

No precipitation occurs.

Snow always falls instead.

Only rain forms directly.

Obavezno

1

What characterizes a warm front overtaking a cold front?

Warm air moves up and over colder air masses.

Cold air moves under warm air.

Warm air stays close to the ground.

Two cold air masses collide.

Obavezno

1

What is a key factor in cloud formation in fronts?

Only cold fronts create clouds.

Humidity has no effect on clouds.

Humidity in rising air leads to cloud formation.

Temperature of the ground is crucial.

Obavezno

What do meteorologists study to predict the weather?

Only temperature changes.

Just humidity levels.

Wind patterns and atmospheric conditions.

Weather maps alone.

Obavezno

1

What do weather symbols on maps indicate?
