First Conditional: real possibility
We are talking about the future. We are thinking about a particular condition or situation in the future, and the result of this condition. There is a realpossibility that this condition will happen.

IF | condition | result |
  | present simple | WILL + base verb |
If | it rains | I will stay at home. |

If | it rains tomorrow | will you stay at home? |
If | it rains tomorrow | what will you do? |
