many interactions occur among systems, such as the atmosphere , biosphere, hydrosphere, and geosphere. Of the systems mentioned which scenario describes an interaction between two different “spheres”.

I’d put atmosphere.

Hope it works!

Mark me as brainliest pls!

Good luck :)

So to find the answer, you would add 15 to 20 and get 35. Then you would add 35 to 6:40 to get 6:75, but to then find the time actually (6:75 isnt a time lol) you would subtract 60 from 75, because there are60 minutes in an hour. You would end up with 7:15.
