Natural wetlands are lands which, due to geological or ecological factors, have a natural supply of watereither from tidal flows, flooding rivers, connections with groundwater, or because they are perched above aquifers or potholes.
Realize that many verbs can be both transitive and intransitive. An action verb with a direct object is transitive while an action verb with no direct object is intransitive. Some verbs, such as arrive, go, lie, sneeze, sit, and die, are always intransitive; it is impossible for a direct object to follow.
The base form of a verb is derived from the verbâs infinitive: to + verb. Four suffixes consistently added to a verbâs base create all forms of a verb used in all tenses: 1. -s creates 3rd person singular / present tense (He talks.) 2. -ing creates the present participle / used with be (He is talking.)
