maw [93]

Answer:

The right answer to this question is: 310k

Explanation:

There's a very good formula that can help us to find this answer, but first, we need to know the temperature scale  in Celsius and Kelvin, there's an image below that will help us gather information.

The formula is quite simple, check it below:

C/5  = K-273/5

putting the values we already have in the formula it would be like this:

37/5 = K-273/5

Cutting out the fives, we can have the final result

37= K-273

37+273 = K

K= 310.

Which of these is a process during which the hydrosphere interacts with the geosphere?
timofeeve [1]
<span>The correct answer is "Absorption of rainfall by soil." The hyrdosphere refers to all water on the earth's surface. The geosphere, in this context, refers to the solid parts of the earth (rocks, sand, etc.) Since rain is part of the hydrosphere and soil is part of the geosphere, rain soaking into the soil would be an interaction between the two. The other choices deal with changes in the hyrdrosphere, but there is no interaction with the geosphere.</span>
