Describe the four causes of imperialism

I don't think there are "the" 4 causes, as in 4 causes widely agreed to be the most important: there were many more causes. But here are 4 causes that I find important:

-political importance and prestige: countries wanted to be better than other countries...
-economical: countries sought wealth, for example natural resouces
-religious: countries sought favors with the pope by converting the "pagans"
- curiousity in the Age of Exploration: the will to discover our planet

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.
