Answers

Answer:

Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.

Explanation:

i'm pretty sure

Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather. So, the correct option is B.

What are Warm and cold fronts?

A warm front forms when a mass of warm air enters a space that previously held cold air. As warm air passes over cooler air, it rises and cools, which can result in the formation of clouds and precipitation. Unlike a cold front, a warm front often brings with it lighter and more widespread precipitation. Warm fronts often bring warm temperatures and high humidity levels.

When a mass of cold air approaches an area that was previously surrounded by warm air, a cold front is formed. When cold air flows into warm air, the warm air is forced to rise rapidly, which can result in thunderstorms and heavy rainfall. More extreme weather changes, such as a sharp drop in temperature and drop in humidity, are often brought about by cold fronts.

So, the correct option is B.

What process occurs when a river velocity increase and why

Answers

Answer:

Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.
