Most skull bones are formed by ossification, but other bones are formed by ossification.

Intramembranous, Endochondral

Explanation:

Fibrous membrane and hyaline cartilage are usually present at the beginning of all bone skeletons in an embryo of six (6)weeks. The difference is that intramembranous ossification develops from the fibrous membrane while that of endochondral from the hyaline cartilage. Ossification is driven by osteoblasts which are the main cell of bones.

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.
