Answer:
d. The amount of water vapor in the atmosphere would be lower because it has not evaporated from the hydrosphere.
Explanation:
Hydrosphere is mass of water found on the water surfaces and above it. While atmosphere is the mass of air surrounding our planet. Hydrosphere includes the water that is found inside the earth's crust, on the surface and also water suspended on the air.
There is interaction between hydrosphere and atmosphere. The water gets evaporated from the hydrosphere and get vaporized to the atmosphere. This affects the humidity of the place.
The humidity tends to be lower in places where the amount of water vapor present in the atmosphere is lower as the water does not get evaporated from hydrosphere.
