Water forms cover about 75% of the Earth’s surface. It is important in sustaining life. Bodies of water or water forms include oceans, seas, bays, lakes, rivers, streams, springs, waterfalls, and ponds.

An ocean is the largest body of saltwater. It is home to many kinds of marine
animals like whales, sharks, turtles, and dolphins. There are five oceans in the world: Pacific, Atlantic, Indian, Arctic, and Antarctic Ocean. The Pacific Ocean is the world’s largest and deepest body of water. It covers almost one-third of Earth’s Surface. The Philippines is located on the western part of the Pacific Ocean.

A sea is also a huge body of saltwater, but it is smaller than an ocean. It is wide and deep and provides home to many sea creatures. The South China Sea, Celebes Sea, Sulu Sea, and Philippine Sea surround the Philippines. Different kinds of plants and animals live in seas.

A bay is smaller than a sea or an ocean. It is a body of saltwater that is partly enclosed by land or a wide stretch of coastline. The Manila Bay in Metro Manila is known for its beautiful sunset view.

A lake is a body of freshwater surrounded by land. In some lakes, water comes from a river. The Taal Lake in Batangas is one of the tourist attractions in the Philippines.

A river is a body of water that may flow into a lake, another river, or the sea. Water in a river flows freely until it reaches the open sea.
