Describe the relationship between the ohm and voltage?

ohm law is

V=IR

Explanation:

according to ohm law :

V that is voltage is directly proportional to the current (I) and resistance (R).

It shows the relationship between the current and voltage which is majorly focused. That if we increases the voltage, current will increases but if resistance increases current will decreases as current and resistance having inverse relationship.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
