Which of the following makes up the largest portion of the hydrosphere a Air B the oceans C the continents D photosynthetic organisms?

The answer would be the Oceans because water makes up a very large portion of the earth in general.

What are the main parts of the hydrosphere?

The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifers.

Can our oceans be saved?

However, the deep blue seas have been put under enormous stress as a result of human activity such as overfishing and pollution. Now, a new review published in Nature provides hope – and an action plan – that our oceans can be restored within 30 years.

How do we save our oceans?

How can you help our ocean?

1. Conserve Water. Use less water so excess runoff and wastewater will not flow into the ocean.
2. Reduce Pollutants. Choose nontoxic chemicals and dispose of herbicides, pesticides, and cleaning products properly.
3. Reduce Waste.
4. Shop Wisely.
5. Reduce Vehicle Pollution.
6. Use Less Energy.
7. Fish Responsibly.
8. Practice Safe Boating.

Why is there a major decline in our oceans?

Oceans are being harmed in a variety of ways. Climate change is causing global ocean temperatures to rise, changing how fish species migrate, affecting how animals reproduce, causing coral reefs to die, and unleashing dangerous pathogens.

Are the oceans losing oxygen?

Oxygen in the oceans is being lost at an unprecedented rate, with “dead zones” proliferating and hundreds more areas showing oxygen dangerously depleted, as a result of the climate emergency and intensive farming, experts have warned.

How are humans affecting oceans?

Pollution and Dumping Human pollution also significantly affects the oceans. In addition, oil spills such as the one resulting from the Deepwater Horizon fire in 2010 can contaminate large stretches of the ocean, wiping out entire populations of fish and other species, and affecting the regional ecosystem for decades.

Which country is called lungs of world?

Amazon rainforest is the most biodiverse region on earth, providing shelter to three million species on plants and animals. Billions of trees absorb tons of carbon dioxide every year and slow down the climate change along with producing 20% of earth’s oxygen, hence named ‘Lungs of Earth.

The answer would be the Oceans because water makes up a very large portion of the earth in general.

What components make up the hydrosphere?

The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifers.

Which examples are part of the hydrosphere?

All of the oceans, lakes, seas and clouds are an example of the hydrosphere. All of the Earth’s water, including surface water (water in oceans, lakes, and rivers), groundwater (water in soil and beneath the Earth’s surface), snowcover, ice, and water in the atmosphere, including water vapor.

How big is the hydrosphere?

The total mass of Earth’s hydrosphere is about 1.4 × 1018 tonnes, which is about 0.023% of Earth’s total mass. At any given time, about 20 × 1012 tonnes of this is in the form of water vapor in the Earth’s atmosphere (for practical purposes, 1 cubic meter of water weighs one tonne).

How much of the hydrosphere is oxygen?

It occurs both as the free element (in the atmosphere) and in the combined form (in the lithosphere and hydrosphere). Its most common and best known compound is probably water. Water contains 88.9% oxygen, by weight.

What is the earth outermost system?

The outermost layer, called the crust, is solid, too. Together, these solid parts are called the lithosphere. Earth’s crust is made up of hard rocks. It is the only part of the Earth that humans see.

What is the crust of the Earth called?

Earth’s outermost, rigid, rocky layer is called the crust. Together the uppermost mantle and the crust act mechanically as a single rigid layer, called the lithosphere.

How is Earth’s core different from the crust?

Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.
