Unformatted text preview: e is tilted toward the Sun, faces the Sun most directly, and receives the largest amount of solar radiation per unit
area. ! If Earth did not tilt on its axis, there would be no seasons!!! Physical Features Have Regional Effects on Climate
! The presence of mountain ranges tends to produce extremes
! In the rain shadow effect, winds from the ocean cool and drop
precipitation on one side of a mountain range and not on the
other side, creating high deserts. ! The presence of an ocean has a moderating influence on temperature because water has a very high specific heat, or
capacity for storing energy. Why Are Organisms Found
Where They Are?
! Biogeography is the study of how organisms are distributed
geographically. ! Phylogeography is the study of the historical processes that
may be responsible for the contemporary geographic
distributions of individuals. What scientific tools are used? ! Interactions with
the abiotic and
affect where a
lives. Abiotic Factors
! The range, or geographical distribution, of every species on
Earth is limited―no organism can live everywhere. ! Because of fitness trade-offs, organisms tend to be adapted
to a limit...
