Explanation:
We use the Simple Present Tense to express habitual actions, that is, something that is done with a certain frequency. It can also be used to express universal truths, that is, facts that are generally accepted as true by most if not all people. Take a look at the sentence below:
9. My sister walks to school every day. (habitual action)
25. The moon goes round the earth. (universal truth)
We use the Present Continuous to express an action that is taking place at the moment of speaking. It can be a shorter action, one that will end soon, or an action that will last for some time in the future. Phrases such as "at the moment" or "right now" commonly appear with this tense. Examples:
6. She is staying in Africa at the moment.
17. Let's go out. It is not raining now.
