Clouds & Fronts

What is the significance of cirrus clouds?

• They indicate stormy weather conditions.

• They are low-altitude clouds that bring rain.

• They indicate fair weather but can also signal a change in the weather.

• They are clouds that form only at night.

What are the characteristics of nimbostratus clouds?

• They are thin, white clouds that bring fair weather.

• They are fluffy, white clouds that indicate thunderstorms.

• They are thick, gray clouds that cover the sky and bring continuous, steady precipitation.

• They are high-altitude clouds that produce little to no precipitation.

Why does warm air rise above cold air?

• Warm air is less dense than cold air, causing it to rise.

• Warm air is heavier than cold air, causing it to sink.

• Warm air contains more moisture than cold air, making it rise.

• Warm air is cooler than cold air, which causes it to rise.

What type of weather front is over North California?

• A cold front is moving through North California.

• A warm front is approaching North California.

• A stationary front is present over North California, where air masses do not move significantly.

• A high-pressure front is dominating North California.

What type of front is characterized by little to no movement?

• A stationary front

• A cold front

• A warm front

• An occluded front

What happens to air pressure when a cold front passes?

• Air pressure decreases due to the warm air rising.

• Air pressure remains constant regardless of the front.

• Air pressure typically rises due to the denser cold air replacing the warm air.

• Air pressure fluctuates randomly during a cold front.

What type of cloud is associated with thunderstorms?

• Cumulonimbus clouds

• Stratus clouds

• Cirrus clouds

• Nimbostratus clouds

What is an occluded front?

• A type of front where two cold fronts meet

• An occluded front occurs when a cold front overtakes a warm front, leading to complex weather patterns.

• A front that forms when warm air rises over cold air

• A boundary between two warm air masses

What is the role of clouds in the water cycle?

• Clouds absorb sunlight and create heat.

• Clouds store water vapor and release it as precipitation.

• Clouds block wind and prevent evaporation.

• Clouds are formed only during storms.

How do clouds form?

• Clouds form when water vapor in the air cools and condenses into tiny water droplets or ice crystals.

• Clouds are formed by the evaporation of water from the ground.

• Clouds are created by the accumulation of dust particles in the atmosphere.

• Clouds form when air pressure increases and traps moisture.
