Answer:
Liters per second is 0.2 LPS
Liters per hour is 720
Explanation:
Divide the litres by the time, than multiply the time of an hour (in seconds) and than multiply the lps by time of an hour in seconds.
Answer:
atmosphere and hydrosphere
Explanation:
The polar ice caps are part of the cryosphere, which in turn is part of the hydrosphere, which is the sphere that contains all the waters on the planet. The atmosphere has been experiencing changes, with the increase of greenhouse gasses being the most noticeable and most important one. These gasses have contributed to the rise of the global temperatures. As the temperatures have been rising, the ice started to melt, thus it was influenced by the atmosphere, and as it is melting it is getting into the ocean water, thus increasing them. The more water there is in liquid form, and the higher the temperatures are, the higher the evaporation will be, so there will an increase in the amount of water vapor in the atmosphere. This is a nice example of the interaction between these two spheres.
