2. Take a bowl of ice, put it out in direct sunshine and note its temperature after every 05 minutes. What type of change in its temperature, do you observe? How much time will it take to melt completely? Now put the same water on a stove and note down its temperature after every 30 seconds. What type of change in its temperature, do you observe now? How much time will it take to boil? Explain your observations with the help of time and temperature chart. (Perform this experiment on a sunny day) (6 marks)

Imagine that you are buying books one by one and then piling them up after reading them. which geologic concept could you use to identify the topmost book as the newest?

The land along the great lakes' coasts is known as "the fruit belt" because of the year-round ideal conditions for fruit farming. how are the coastal air temperatures affected by the great lakes, creating profitable conditions for fruit farmers? a) during winter, the great lakes act as a heat source, to regulate extreme temperatures in the surrounding areas. b) hills and mountains surrounding the great lakes area force warm air downward toward the lake, making the coastal areas warmer. c) the elevation of the great lakes is higher than the surrounding areas, causing air to heat and cool slowly, without damaging crops. d) dry regions surrounding the great lakes cause warm air masses to move quickly across the lakes, resulting in more stable temperatures.
