Question

The sun is in the sky. Clouds with blue arrows pointing down toward water. The arrows are circled. An arrow is pointing from the water inland showing wind direction. Red arrows are pointing up from the land to the sky. What do the arrows in the circle indicate? Warm air is rising. Cool air is sinking. Cool air is less dense. Warm air is more dense.

Answer 1

The blue arrows in circles indicate that cool air is sinking

Step-by-step explanation:

Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.

So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.

Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.
