Answer:
First, rain will have to occur. The lake and surfaces will have water in them, after that it will a while for the surface to evaporate into water vapour, after that the water vapour will condense into water droplets and when the clouds are too heavy because of too much water droplets in them, it will start to rain again and this cycle will keep going on continuously.
Answer:
The sound will reach my ear in a shorter time in Scenario 1.
The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.
