Asteep pressure gradient

produces light winds

is only possible in the tropics

is depicted by widely spaced isobars

produces strong winds

A steep pressure gradient produces strong wind

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

the fossil record provides evidence of a common ancestor to many species.
