How do you explain sea to a child?
A sea is a body of saltwater much smaller than an ocean, but technically all seas and oceans are joined together in one enormous world ocean. Seas are usually the barrier between land and ocean, or are pretty much surrounded by land.
In general, a sea is defined as a portion of the ocean that is partly surrounded by land. Given that definition, there are about 50 seas around the world. But that number includes water bodies not always thought of as seas, such as the Gulf of Mexico and the Hudson Bay.
Fun Ocean Facts
Around 97% of all water is in the oceans and they cover around 71% of Earth's surface. Pacific Ocean is the biggest one. You can find mountains and volcanoes on the bottom of oceans. The deepest point in the ocean is the Mariana Trench.
Seas are large bodies of salt water that are connected to oceans, and they are often partially surrounded by land. There are many cool creatures living in the sea, and these plants and animals are called marine life since they are in the sea. Let's find out about some sensational sea dwellers!

Despite their size, the lakes are beholden to what happens on the land that surrounds them in a way larger seas are not. For example, precipitation and runoff that drains into the lakes significantly affects their water levels, chemical composition, and other characteristics.
Words to Describe Sea and Ocean.
It is another Proto-Germanic word, saiwa-, that developed into the Old English sæ (“sheet of water, sea, lake, pool”), giving us the English word “sea”. Functionally, there is but one ocean.
- high seas.

By understanding how everything is connected in the ocean and how we interact with it as humans, children will learn to care and protect the ocean because they will want it to be a better place – not just for the fish, but for them too.
