The amount of solar radiation changes due to the
WILL MARK BRAINLIEST!!

Due to the variations in the sun-earth distance.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i would say b

explanation:

but i think i would need more information than that
