How is groundwater formed?

a. when water condenses on particles of soil

b. when water runs along the top of the soil

c. when water percolates down through the soil

d. when water evaporates into the air from the soil

I think it is C because groundwater is formed when the water seeps into the ground.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
