Will give form at convergent boundaries, and form at divergent boundaries. a. cracks, volcanoes c. volcanoes, cracks b. volcanoes, mid-oceanic ridges d. mid-oceanic ridges, cracks

b. volcanoes, mid-oceanic ridges

A convergent boundary is a sort of border where two plates gather and begin to push against one another. Convergent boundaries form powerful tremors, as well as volcanic ridges or islands when the submerging oceanic plate vanishes.

In plate tectonics, a diverging boundary or diverging plate boundary is a narrow point that exists among two tectonic plates that are shifting away from each other. Most active diverging plate frames occur within oceanic plates and subsist as mid-oceanic ridges.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .

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.
