Because during incubation moisture will form at the top of the petri dish. Inverting the dish prevents it from dropping into whatever you have in the petri dish.

Why petri dish is inverted in incubation in membrane filtration method?
This inversion prevents moisture condensing on the surface of the plate. That would make a problem in that the growth on the plate would be "distorted" by the water making ID more difficult.
Why are petri plate inverted when put in the incubator.?
to prevent condenstion of the gel
What is a petri disk?
A petri dish is a small glass plate used for, among other things, growing bacteria cultures to examine under a microscope.
Who discovered the Petri dish?
The Petri dish is named after German bacteriologist Julius Richard Petri. Petri worked as a military physician for the German army and was assigned to a laboratory in Berlin’s Imperial Health Office in 1887. Building on methods such as the bell jar on a glass plate technique, Petri invented a culture dish very similar to the one we are familiar with today. He named the invention after himself and went on to write a 300-word paper about how to use the dish.
What is the function of petri-dish in the microbiology lab?
A Petri dish (or Petri plate or cell culture dish) is a shallow glass or plastic cylindricallidded dish that biologists use to culture cells[1]or small moss plants.[2

Why is it important to invert a petri plate during incubation?
This is to stop condensation from forming on the top of the lid. Condensation causes two problems (1) It will allow contamination to enter into the dish by moving accross the water film from the outside (2) It can create a tight seal and prevent oxygen entering the petri dish making it go anerobic.
Why agar plates inverted during the incubation period?
Bacteria love to grow in moist damp places - if you haven't noticed, condensation causes water droplets to form on the top of the lid and if you incubated the plate with lid on top when the water runs down the sides of the plate it can easily contaminate your culture.
Shallow plate used in science lab?
A shallow plate which is used in a science lab is known as a petri dish.
What is a petri disk?

How do you mix contents in a tube that you are preparing to pour into a Petri plate bacteria?
Carefully.
What is each clump of growth on found on a petri plate?
The clumps of growth are called colonies.
What would you need to do to determine whether bacteria growing on a petri plate are anaerobes?
some sense
Why should you only lift one edge of the lid of the petri plate when carrying out a streak plate?
There is a lower chance of contamination from the air and the things surrounding it.
What are the advantages and disadvantages of pour plate method?
Advantages: 1. Counts only living cells 2. Standardized test - used worldwide Disadvantages: 1. 1-2 days of incubation 2. Melted, heated agar 3. Osmotic shock
What is a science test pate called?
If you meant to type "test plate" then what I think you are referring to is called a Petri dish.
