Why does a warm front typically bring light to moderate rain rather than thunderstorms?
A. The warm air rises too rapidly, preventing storm formation.
B. The slope of the front is gradual, leading to steady lifting of air over a wide area.
C. Warm fronts are associated with high-pressure systems that limit precipitation.
D. Warm fronts lack the moisture needed for heavy rainfall.
B. The slope of the front is gradual, leading to steady lifting of air over a wide area is why warm front typically bring light to moderate rain.
How can a stationary front contribute to flooding in certain regions?

B. The prolonged rainfall associated with a stationary front can oversaturate the ground.
C. The stationary front causes rapid temperature changes, melting snow and increasing runoff.
D. The stationary air masses prevent cloud formation, leading to trapped heat.
B. The prolonged rainfall associated with a stationary front can oversaturate the ground which can cause flooding.
