How do I go about creating a union query?

Assuming this post stems from your prior post, You received some very
good advice. Your design is faulty. You need to redesign your DB.
All of this info should be in ONE table. See George's post in your
other thread.

Easiest way is to create a select query in the standard method and then
switch to the SQL view from the design view. You should see something like

SELECT AField, BField, CField
FROM SomeTable
WHERE AField = "xxx";

Delete the semicolon
Type UNION ALL

NOW type in the query for the second table

SELECT AField, BField, CField
FROM SomeTable
WHERE AField = "xxx"

UNION ALL

SELECT DField, EField, FField
FROM SomeOtherTable
WHERE AField = "xxx"

Each query in the UNION must have the same number of fields and the field
types must be alike. So in the sample AField and DField must both be text
fields. If BField is a date field then EField must be a date field. If
CField is a number field then FField must be a number field.
