Which type of information is pseudoscience based on?

Answers

Answer:

Unsupported claims

Explanation:

Pseudoscience is kind of a fake science. it uses scientifical terms to trick people into thinking it actually is science. It uses words like "quantum" in a sentence such as "Buy this quantum phone charger for your phone to charge 2x the normal speed!" Since it has the "quantum" in it, some people do actually think it's scientific, and fall for that ad.

So, the answer is unsupported claims because those claims such as "Drinking milk and eating mango at the same time lead you to death" are fake beliefs that don't have any scientifical evidence.

How does the suns energy cause a hurricane to form

Answers

The sun heats the land and oceans unevenly, creating areas of upwards and downwards moving air as well as pressure differences. This causes air to flow from one area to another. For hurricanes the sun heats the ocean, causing some water to evaporate. The water vapor powers convection in storms which can then strengthen and organize to form hurricanes. Hope this helps:)
