Difference Between Sea and Ocean

Sea and Ocean:

The ocean is a large body of salt water that surrounds the continents of the Earth. The ocean is divided into several different parts, including the Pacific, Atlantic, and Indian oceans. The ocean is a major source of food and income for many people, and it is also a major transportation route. The ocean is home to a variety of plants and animals, including whales, dolphins, and sharks.

    What is an Ocean?

    An ocean is a large body of salt water that occupies about two-thirds of the Earth’s surface and is bounded by continents. Oceans are important for transportation, trade, and energy resources.


    are the rise and fall of the ocean’s surface due to the gravitational tug of the moon and sun. The tides are highest when the moon is full or new and lowest when it is quarter or three-quarter.


    are disturbances that move through a medium. A medium can be a solid, liquid, or gas.

    Waves can be created by a variety of things. For example, when you drop a rock into a pool of water, the water starts to ripple. The disturbance that the rock creates moves through the water and creates waves. Another example of waves is when you sing in a room with a lot of echo. The sound that you create moves through the air and creates waves.

    What is a Sea?

    A sea is a large area of salt water that is part of the ocean.


    are formed when waves and currents erode and carry away pieces of the land’s surface. Over time, this continuous process builds up a ridge of sand, pebbles, and rocks that parallels the shoreline. The height and width of a coast depends on the strength of the waves and the type of material they are eroding.

    The ocean’s waves are generated by the wind. As the wind blows, it creates waves that travel out from the shore. The strength of the waves depends on the wind speed and the distance from the shore. The larger the wave, the more energy it has, and the more erosion it can cause.

    Waves can erode the land in two ways. First, the wave can crash against the shoreline and carry away pieces of soil, sand, and rocks. Second, the wave can pull the material from the shoreline out to sea. This process is called longshore drift.

    The material that is eroded is carried away by the waves and currents. This material is then deposited on the coast, where it builds up a ridge of sand, pebbles, and rocks. The height and width of the ridge depends on the strength of the waves and the type of material they are eroding.

    Creatures of the Sea

    The sea is a vast and varied place, home to creatures of all shapes and sizes. Some of the most common creatures that live in the sea are fish, dolphins, whales, and sharks. Fish can be found in all kinds of different environments, from the deepest parts of the ocean to the shallows near the shore. They vary in size and color, and can be predators or prey. Dolphins are closely related to whales, and both are highly intelligent creatures that can be found in all parts of the ocean. Dolphins are known for their playful behavior, and often swim alongside boats and jump out of the water. Whales are the largest animals that live in the sea, and can be found in all of the world’s oceans. They are eaters of plankton and small fish, and can grow to be over 50 feet long. Sharks are perhaps the most feared creatures in the sea, and are found in all parts of the world’s oceans. They are predators that eat fish, seals, and other sharks.

    Difference Between Ocean and Sea

    The main difference between ocean and sea is that the ocean is much larger than the sea. The ocean is the largest and deepest of the world’s five oceans, making up about 71% of the Earth’s surface. The sea, on the other hand, is a much smaller body of water, making up about 29% of the Earth’s surface.

    Human uses of the Ocean Bodies

    The ocean has a lot of different uses. People use it for transportation, fishing, swimming, and more.

    Threats to Marine Biodiversity

    The biggest threats to marine biodiversity are climate change, ocean acidification, and overfishing.

    Climate change is caused by the increase of greenhouse gases in the atmosphere, which trap heat and cause the Earth to warm. This warming causes the ocean to warm and become more acidic, which harms marine life.

    Overfishing can happen when too many fish are caught, which can lead to a decline in fish populations. Overfishing can also damage the habitats of fish, which can harm the fish populations.

    Oil spills pose a serious environmental risk, particularly when they occur in coastal and marine ecosystems. They can cause extensive damage to the environment, both through the release of oil and the subsequent contamination of the water column and seabed. The potential ecological impacts of oil spills range from the death of marine organisms to long-term changes in the structure and functioning of ecosystems. There is a large body of scientific literature on the environmental risks posed by oil spills, and this review provides an overview of the key findings.

    The review first looks at the factors that influence the magnitude of the environmental impact of an oil spill. These include the type and quantity of oil spilled, the sensitivity of the
