What do you find in the sea?

* Water: The most obvious thing you'll find in the sea is water! The oceans cover about 71% of the Earth's surface, and they contain about 97% of the Earth's water.

* Salt: The ocean is also very salty. The average salinity of the ocean is about 3.5%, which means that for every liter of seawater, there are about 35 grams of salt.

* Waves: The ocean is constantly in motion, and this motion creates waves. Waves can be small and gentle, or they can be large and powerful.

* Tides: The ocean's tides are caused by the gravitational pull of the moon and the sun. Tides can cause the water level to rise and fall by several feet.

* Marine life: The ocean is home to a vast variety of marine life, including fish, whales, dolphins, sharks, and sea turtles. There are also many different types of plants in the ocean, including seaweed, kelp, and coral.

* Shipwrecks: The ocean is also home to many shipwrecks. Some shipwrecks are very old, while others are more recent. Shipwrecks can be found in all parts of the world, and they can provide a glimpse into the past.

* Treasure: The ocean is also home to many treasures. Some treasures are natural, such as pearls and gold nuggets. Other treasures are man-made, such as sunken treasure ships.
