Which verb tense indicates actions that are continuous or ongoing?

The verb tense that indicates actions that are continuous or ongoing is present tense. Present tense is utilized to discuss actions that are currently happening or general truths. For instance, when we state "The teacher teaches," we are showing that this action is happening in the present time and can occur repeatedly, emphasizing continuity.

The perfect tense conveys actions that have been completed and often relates past actions to the present but does not inherently indicate ongoing or continuous actions. The simple past tense refers specifically to actions completed in the past with no implication of continuity into the present. Future tense describes actions that will occur later but does not indicate whether they are ongoing at the time of speaking.

Thus, the present tense is the correct choice for indicating continuous or ongoing actions.
