Sand doesn't directly cause weathering because sand is made via weathering. When rocks get weathered they become sand. But maybe when the sand and wind work together they might be able to weather some rocks

Sand is used to cause weathering but it alone does not cause weathering. (Pretty sure)

Answer:

the size of Ca is the greatest ,then Mg is the greater on size than Be

Explanation:

if you make the electron configuration for each of the elements, what is the main difference u gonna see ?

Be 4 1s2/2s2

Mg 12 1s2 /2s2 2p6/3s2

Ca 20 1s2 /2s2 2p6/3s2 3p6 3d/4s2

see that all the elements are in the same group but are in different period

u gonna see the last electron valance shell in Ca are too far from its nucleus but in Be the last electrons are too close and more attracted to the atom's nucleus , so the size of Ca is the biggest then Mg then Be
