Explanation:
The tense we use to talk about things that are happening right now is called the present tense. Depending on the nature of the actions/events we're talking about, we can use one out of four types of the present tense: the present simple, present continuous, present perfect simple, or present perfect continuous tense.
We use the present simple tense when we want to talk about fixed habits or routines, i.e. things that don't change.
We use the present continuous tense when we want to talk about actions or conditions that are happening now, frequently, and may continue into the future.
