Description:

The correct answer is:

✅ Weather front

What Happens at a Weather Front?

When two air masses with different temperature, humidity, or density meet, they form a front, leading to:

Clouds

Precipitation (rain, snow, storms)

Wind shifts

Types of Fronts:

Cold Front: Cold air pushes under warm air, causing thunderstorms.

Warm Front: Warm air rises over cold air, bringing steady rain.

Stationary Front: Stalled boundary → prolonged rain/snow.

Occluded Front: Complex mix of air masses → varied weather.

Why Not the Others?

❌ Weather horizon: Not a meteorological term.

❌ Weather stationary: Misleading—it’s a type of front, not the boundary itself.

Fun Fact: Fronts are why weather changes so fast! 🌧️💨
