Is H2O a novel?

Yes, it is. 'H2O' by Virginia Bergin is indeed a novel.

No, H2O itself is not a cause of acid rain. Acid rain is typically caused by the presence of pollutants like sulfur dioxide and nitrogen oxides in the atmosphere.

It depends on the specific H2O concepts. Some concepts are facts. For example, water (H2O) has a unique molecular structure that gives it its well - known properties like high heat capacity. This is a scientific fact. However, some might spread misinformation about H2O, like false claims regarding its ability to cure all diseases when consumed in large amounts, which is clearly fiction.

There were many animes that were similar to Summer Sunshine, such as Summer Sunshine (H2O)'s follow-up, Summer Sunshine Kiss (H2O-CHILI), Summer Sunshine's OVAs and theatres, and Summer Sunshine's manga.

I'm not sure exactly as I haven't read it in detail. But generally, it might be about stories and events that are somehow related to water (h2o) and the concept of footprints in the sand, which could symbolize memories or a journey in the context of the visual novel.

I'm not sure exactly. It could be an abbreviation specific to a particular story or genre that's not widely known.

Since I'm not familiar with this specific visual novel, it's hard to say who the main characters are. However, based on the title, there could be characters who have a special relationship with water. For example, there might be a fisherman or a beachcomber. Or perhaps there are characters who are on a journey of self - discovery related to the footprints in the sand metaphor.

One common theme is the clash of different worlds. Since Percy comes from a world of demigods and H2O is about mermaids and a more aquatic - focused world, there's often a lot of adjustment and misunderstandings as the characters from both universes interact.

Love and relationships are also popular themes. The h2o characters might fall in love with characters from the other crossover story. This could create interesting relationship dynamics and storylines, like a mermaid falling for a human from a different fictional world.

Once upon a time in the underwater world where the mermaids from H2O and Mako Mermaids co - existed. A group of mermaids from both series decided to have a friendly competition. The H2O mermaids showed off their unique ability to turn water into different shapes, while the Mako Mermaids demonstrated their incredible speed in the water. As they interacted, they learned new things from each other and became great friends, vowing to protect the ocean together against any threats.
