If you are at the same location, how would your shadow differ from 7 am to 5 pm

The sun is nearly above you in the mornings, which makes your shadow short. In the evenings, the sun is nearly beside, infront or behind you, do you shadow is a lot longer.

Explanation:

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
