The oceans cover over 70% of our world and contain millions of living things. They also regulate the temperature of Earth and provide us with food, oxygen, and water. But do you know how the seas were formed? Why are they significant? And how do they influence our climate? Let’s discuss these questions in easy language.

How Did the Seas Form?
About 4 billion years ago, Earth was hot and volcanoes covered it. It cooled down over time, and steam in the air condensed into rain. This rain continued to fall for thousands of years and filled the low lying areas and created the first seas.
Other scientists think that comets carrying ice were the ones to bring water to our planet. Regardless of the way it came, these giant water reservoirs formed the beginning of life on our planet.
Why are Seas Important?
Seas are not enormous pools of water. They are vital for life in a number of different ways:
They Provide Us With Oxygen: Small sea plants named phytoplankton make more than half the oxygen we use.
They Regulate Temperature: The seas warm up from the sun and distribute it all around the world, maintaining our climate stable.
They Offer Nourishment: Fish and other seafood form the major part of diet in many human populations across the world.
They Bear Life: As small planktons to giant whales, seas house incredible living creatures.
They Facilitate Commerce: Seacraft takes along commodities between nations, hence allowing commerce to flow.
Fantastic Sea Animals
Oceans are home to all sorts of creatures:
Plankton: Little plants and animals floating around in the water.
Fish: From the small sardine to the large shark, fish belong to the sea.
Mammals: Dolphins, whales, and seals are breathing animals but reside underwater.
Reptiles: Sea turtles and certain sea snakes inhabit the ocean.
Invertebrates: Octopuses, jellyfish, and crabs do not have backbones but are common in the sea.
How Do Seas Influence the Climate?
Seas have a tremendous impact on the climate of the Earth:
They Store Heat: The ocean heats up from the sun and redistributes it around the globe. This keeps the temperature of the Earth stable.
They Absorb Carbon Dioxide: Seas absorb carbon dioxide (CO₂) from the atmosphere, which regulates global warming.
They Influence Weather: Ocean currents and winds regulate rain, storms, and even hurricanes.
Problems Facing the Seas
Although the seas help us, they are facing very serious problems:
Pollution: Plastic, oil spills, and waste hurt sea creatures.
Overfishing: Humans take too many fish, which makes it difficult for certain kinds of fish to live.
Climate Change: Warmth in the environment causes issues such as coral bleaching, which kills sea life.
Ocean Acidification: Excess CO₂ in water makes it more difficult for animals like corals and shellfish to develop.
How Can We Protect the Seas?
Saving the seas is crucial for all of us. Here’s how we can assist:
Use Less Plastic: Plastic pollution kills sea creatures, so reusing bags and bottles can help.
Support Sustainable Fishing: Buying seafood from sustainable sources protects fish stocks.
Save Water: Saving water at home saves waste that ends up in the seas.
Learn and Share: Educating others about the significance of the seas protects them for generations to come.
Conclusion
The oceans are a valuable portion of our planet. They support life, bring us food, and maintain our stable climate. However, they also have much danger. In Anee’s School, we care about giving the best possible education and distributing Earth knowledge. If we can learn about the seas and start to protect them little by little, we will be able to change a great deal.
If we all come together, we can keep the oceans healthy for our future! ????
