What types of rocks initially form from deposition?
a) igneous
b) basaltic
c) metamorphic
d) sedimentary

d) sedimentary

Explanation:

Sedimentary rocks are kinds of rocks that are formed by the accumulation of small particles, which is called deposition, they are often formed in bodies of water where the particles are depositated and eventually mix with carbon and other minerals to form rocks. The most common happens in the bottom of the seas and oceans because of the deposition and then the pressure that the water above applies on the particles, it compresses the particles forming rocks.

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.  

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
