The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

How does the ocean influence Earth?
The ocean influences weather and climate by storing solar radiation, distributing heat and moisture around the globe, and driving weather systems. ... Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.
What are 2/3 ways that the ocean impacts climate?
The ocean plays a fundamental role in mitigating climate change by serving as a major heat and carbon sink. The ocean also bears the brunt of climate change, as evidenced by changes in temperature, currents and sea level rise, all of which affect the health of marine species, nearshore and deep ocean ecosystems.
What are 3 impacts on ocean life?
Students learn about three examples of human impacts on marine life: migration patterns and shipping, algal blooms and water chemistry, and marine debris. Some of these impacts are due to human activity in the ocean, and some impacts on the ocean are due to human activity on land.
What makes an ocean an ocean?
What is an ocean? An ocean is a continuous body of salt water that is contained in an enormous basin on Earth's surface. The major oceans and their marginal seas cover nearly 71 percent of Earth's surface, with an average depth of 3,688 metres (12,100 feet).
What are the two causes of rising sea levels?
What's causing sea level to rise? Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.
How the ocean is changing?
As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea level. ... Changes in ocean systems generally occur over much longer time periods than in the atmosphere, where storms can form and dissipate in a single day.
How does ocean warming affect sea life?
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
How do humans depend on the ocean?
The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
How are oceans and seas useful to us Class 3?
We live on a blue planet, with oceans and seas covering more than 70 per cent of the Earth's surface. Oceans feed us, regulate our climate, and generate most of the oxygen we breathe.
What affects the ocean?
In our oceans, there are a number of environmental conditions that affect the growth, survival and productivity of marine organisms. These include light availability, oxygen levels, water movement, salinity, density and pH.
How humans are killing the ocean?
In conclusion, the main human threats to marine life are shark hunting, overfishing, inadequate protection, tourism, shipping, oil and gas, pollution, aquaculture and climate change. These are activities that cause fish and plants in the aquatic habitat to become extinct.
What are 5 ways humans negatively impact our oceans?
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming.
