How does earth's orbit influence climate

The tilt of its axis is how it affects our climate. You see the earth has a tilt so we are not really going in a true circle. but when the top hemisphere is tilted to the sun we have summer, if tilted away winter. Its really a simple consept if you think about it :)

Texas’ gulf coastal plains are the western extension of the coastal plain extending from the atlantic ocean to beyond the rio grande. its characteristic rolling to hilly surface covered with a heavy growth of pine and hardwoods extends into east texas. in the increasingly arid west, however, its forests become secondary in nature, consisting largely of post oaks and, farther west, prairies and brushlands.
