  1. Mar 5, 2024 · The ocean covers 70 percent of Earth 's surface. It contains about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth. The ocean makes all life on Earth possible, and makes the planet appear blue when viewed from space.

    Earth isn’t the only ocean world in our solar system. Water on other worlds exists in diverse forms on moons, dwarf planets, and even comets. Ice, water vapor in the atmosphere, and oceans on other worlds offer clues in the quest to discover life beyond our home planet.

    This system is made up of all the water on Earth, including water that is liquid, solid (ice and snow) or vapour (in the atmosphere). The ocean contains most of the water on the planet – far more than the freshwater in ice, lakes, rivers, groundwater and clouds.

    The atmosphere is the layer of gas around the planet that supports life and climate. There is a lot of movement between the ocean and atmosphere. Water is exchanged as part of the water cycle, and carbon dioxide is exchanged as part of the carbon cycle. In some places, the ocean gives up its heat to the atmosphere – in others, it takes up heat. Thi...

    The biosphere includes all living things and their environments. The sunlit upper part of the ocean supports vast food webs, from microscopic plants and animals in plankton to huge marine predators. Life also thrives in the dark ocean depths. The ocean supports this life because of the nutrients and warmth that it contains and circulates.

    There is a lot of exchange of material between the ocean and the geosphere – the land and rock of the Earth. The ocean takes material from the edge of the land through erosion, and rivers add material from inland. Vast amounts of sediments settle to the bottom of the ocean, and these eventually get turned into sedimentary rocks (see the rock cycle ...

    Liquid water enters the ocean through rain, rivers and melting ice. Water vapour evaporates from the ocean into the atmosphere to form clouds. Every year, 300,000 cubic kilometres of water evaporates into the atmosphere. Much falls back into the ocean, but a third of it condenses and falls onto land as rain and snow.

    The ocean is one of the main stores of carbon on Earth. Most of the carbon is obtained from the atmosphere as carbon dioxide. Chemical and biological processes in the upper ocean combine the carbon with other chemicals, and much of the resulting material (mostly calcium carbonate) ends up sinking into the ocean deeps. Here, the carbon cycle overlap...

    The ocean continually batters the edge of the land, eroding it, breaking down the rock and transporting it out to sea. Chemical and biological processes in the ocean also ensure that there is a build-up of sediment at the bottom of the ocean. Over millions of years, these sediments are physically and chemically changed into sedimentary rock. Moveme...

  3. The ocean emits some of its heat up into the atmosphere, both in the form of thermal energy and water vapor, creating winds and rain clouds. In turn, surface winds push against the surface of the ocean, creating currents that help control the distribution of warm and cold waters.

  4. As Earth warms, water in the ocean soaks up energy (heat) and distributes it more evenly across the planet. The ocean also absorbs carbon dioxide from Earth’s atmosphere. The additional heat and carbon dioxide in the ocean can change the environment for the many plants and animals that live there.

  5. Aug 16, 2024 · The atmosphere and ocean work in concert to orchestrate Earth’s weather and climate. The air–sea boundary exchanges heat, water, gases, and chemicals between the atmosphere and the ocean. The atmosphere connects to the ocean; the ocean connects to the atmosphere.

  7. The ocean influences weather and climate by storing solar radiation, distributing heat and moisture around the globe, and driving weather systems. This map of sea surface temperature illustrates how heat is distributed across the global ocean. Download image (jpg, 105 KB).
