What are the two major energy sources obtained from the ocean floor Group of answer choices?
The ocean can produce two types of energy: thermal energy from the sun’s heat and mechanical energy from the tides and waves. Oceans cover more than 70% of Earth’s surface making them the world’s largest solar collectors.
Which two energy resources are found under the ocean bed?
The ocean floor contains energy sources (petroleum and gas) and raw materials (sand and gravel phosphorite corals and other biogenic carbonates heavy metal ores). Also the sea floor is used as a dump site for waste which represents a considerable economic value.
What are the main energy products currently being obtained from the ocean floor?
Oil and natural gas are the main energy products currently being obtained from the ocean floor. Gas hydrates are compact chemical structures made of water and natural gas.
What areas of the ocean contain major deposits of energy resources?
The OCS is divided into four regions: the Atlantic Region the Gulf of Mexico Region the Pacific Region and the Alaska Region. Petroleum and natural gas impact our lives in many ways every day. Together they supply more than 60% of our nation’s energy.
Which of the following types of energy is derived from oceans Mcq?
Explanation: The process of generating energy by using temperature difference (or gradient) varying with depth of seawater is called Ocean thermal energy conversion (OTEC).
What kind of energy does an ocean wave possess?
Ocean Wave Energy (Hydrokinetic)
Ocean waves contain tremendous energy potential. Wave power devices extract energy directly from the surface motion of ocean waves. In many areas of the world the wind blows with enough consistency and force to provide continuous waves along the shoreline.
Which energy source is formed at the bottom of the ocean?
What other resources can be found on the ocean floor?
The seafloor contains deposits of minerals that we we use in everyday life such as copper zinc nickel gold silver and phosphorus.
What is the source of energy in deep sea?
chemosynthesis
The three main sources of energy and nutrients for deep sea communities are marine snow whale falls and chemosynthesis at hydrothermal vents and cold seeps.
Is the majority of the world’s oil is produced from ocean floor resources?
The area covered by the ocean basin floor is comparable to the percentage of land on Earth’s surface that is above sea level. … The majority of the world’s oil is produced from ocean floor resources.
How do manganese nodules form?
How are evaporative salts formed?
When a pool (or pond) of seawater is stagnant for a while it allows the sunlight to heat the water. As the water evaporates it leaves behind the sodium (and other elements like chlorine). When enough water has evaporated sodium and chlorine like to bond together to form solid halite (salt).
Which of the following minerals are obtained from oceans?
– We find chloride sodium magnesium minerals in good amounts in the ocean water.
What minerals are obtained from the ocean?

- Potassium. …
- Magnesium. …
- Sand and Gravel. …
- Limestone and Gypsum. …
- Manganese Nodules. …
- Phosphorites. …
- Metal Deposits Associated with Volcanism and Seafloor Vents.
What resources do we get from the Pacific ocean?
Many nodules that are rich in manganese nickel copper and cobalt are particularly widespread in the deep basins of the Pacific and Indian Oceans.
What type of energy is wave energy Mcq?
Explanation: Kinetic energy that results from the oscillation of water is called wave energy.
Which of the following is the source of energy Mcq?
…
Sources of Energy Class 10 MCQs Questions with Answers.
| Column I | Column II |
|---|---|
| 1. Thermal power plant | (c) Use coal petroleum and natural gas to produce thermal electricity |
| 2. Hydro power plant | (e) Dams are constructed for power generation |
| 3. Major component of biogas | (a) Methane |
What is ocean thermal energy Mcq?
Explanation: The ocean thermal energy conversion uses the temperature difference between cold water and hot water to produce electricity. … The OTEC plant pump the sea water and run the power cycle. It is developed in 1880.
What is ocean current energy?
What is sea water energy?
Marine energy or marine power (also sometimes referred to as ocean energy ocean power or marine and hydrokinetic energy) refers to the energy carried by ocean waves tides salinity and ocean temperature differences.
How do we get energy from ocean waves?
- Wind blows across the ocean creating waves. …
- Waves approach land. …
- Waves encounter machines. …
- Machines convert waves into electricity. …
- Electricity is applied to the grid or other needs.
What’s at the bottom of the ocean floor?
How are fossil fuels brought up from the bottom of the ocean?
Formation and exploration of fossil fuels
Gas and oil form in the sea over a period of millions of years as the remains of animals and plants sink to the ocean floor. Combined with particles flushed from the land they are buried and compressed into layers of sediment several kilometres thick on the ocean floor.
Which is obtained from the sea floor?
Minerals obtained from the sea floor include sodium magnesium potassium chloride calcium. Explanation: The sea bed is covered wholly by sand and gravel and contains many metals like gold silver cobalt zinc and manganese embedded within it. Diamonds too are mined from the deep sea.
Are there resources at the bottom of the ocean?
The deep sea contains many different resources available for extraction including silver gold copper manganese cobalt and zinc. These raw materials are found in various forms on the sea floor.
What is the most common rock on the ocean floor?
What is the source of energy for aquatic animals?
Stable carbon and nitrogen isotope ratios in autotrophs aquatic invertebrates and fishes from the Orinoco River floodplain of Venezuela reveal that microalgae including both phytoplankton and epiphytic (attached) forms are predominant energy sources for many aquatic animals even though aquatic vascular plants are …
What is the deep ocean floor?
What are the main regions of the ocean floor?
The ocean floor or seabed can be divided into three major regions: the continental margins abyssal plains and mid-ocean ridges.
How is oil extracted from the ocean floor?
Like other deposits they are extracted by drilling a hole down through the rocks into the oil or gas. For undersea deposits the drills are mounted on a platform called a drilling rig. The oil or gas is usually pumped ashore through pipelines. Hundreds of people work on a large oil rig.
How do you get oil from the ocean floor?
An offshore drilling rig like Deepwater Horizon can reach 10 000 feet to the ocean’s floor — then drill over 30 000 more feet into the rock to extract the oil.
Where does oil come from in the ocean?
What are the two possible sources of manganese nodules that are found in the ocean floor?
There are three main sources of Mn in the nodules: sea water early diagenesis and hydrothermal activity.
