  Arctic Ocean
- C.
  
  Pacific Ocean
- D.
  
  Atlantic Ocean
Correct Answer
B. Arctic Ocean

Explanation
The Arctic Ocean is the smallest ocean among the options given. It is located in the Northern Hemisphere and is surrounded by the landmasses of North America, Europe, and Asia. The Arctic Ocean is significantly smaller in size compared to the other three oceans mentioned.

3.

What percentage of the Earth's surface does ocean cover?
- A.
  
  69%
- B.
  
  70%
- C.
  
  71%
- D.
  
  72%
Correct Answer
C. 71%

Explanation
The correct answer is 71%. This is because the Earth's surface is predominantly covered by oceans, which make up approximately 71% of the total surface area. The remaining percentage is covered by landmasses such as continents and islands.

4.

What percentage of Earth's biosphere does ocean cover?
- A.
  
  87%
- B.
  
  88%
- C.
  
  89%
- D.
  
  90%
Correct Answer
D. 90%

Explanation
The ocean covers approximately 90% of Earth's biosphere. This means that the majority of the Earth's living organisms and ecosystems exist in the ocean. The vastness of the ocean plays a crucial role in supporting life on our planet, providing habitat for countless species and contributing to global climate regulation.

5.

Which of these processes does ocean help in forming?
- A.
  
  Carbon cycle
- B.
  
  Nitrogen cycle
- C.
  
  Water cycle
- D.
  
  Dehydration
Correct Answer
A. Carbon cycle

Explanation
The ocean helps in forming the carbon cycle. The carbon cycle refers to the movement of carbon between the atmosphere, land, and ocean. The ocean plays a crucial role in this cycle by absorbing carbon dioxide from the atmosphere through a process called carbon sequestration. This helps to regulate the amount of carbon dioxide in the atmosphere and mitigate climate change. Additionally, the ocean acts as a carbon sink, storing large amounts of carbon in the form of dissolved inorganic carbon and organic matter.

6.

What percentage of the Earth's water is contained by ocean?
- A.
  
  96%
- B.
  
  97%
- C.
  
  98%
- D.
  
  99%
Correct Answer
B. 97%

Explanation
Approximately 97% of the Earth's water is contained by the ocean. This is because the ocean covers a vast majority of the Earth's surface, and it holds a significant amount of water in the form of saltwater. The remaining 3% of the Earth's water is freshwater, which is found in rivers, lakes, groundwater, and ice caps.

Rate this question:
7.

What is the name given to those who study oceans?
- A.
  
  Oceanist
- B.
  
  Oceanologist
- C.
  
  Oceanographer
- D.
  
  Oceanarologist
Correct Answer
C. OceanograpHer

Explanation
An oceanographer is a scientist who studies the oceans. They investigate various aspects of the ocean, such as its physical properties, marine life, and the interactions between the ocean and the atmosphere. They use various techniques and tools to collect data and analyze it to understand the complex systems and processes that occur in the oceans. Oceanographers play a crucial role in studying and monitoring the health of the oceans and their impact on the Earth's climate and ecosystems.

8.

Which of these animals cannot be found in oceans?
- A.
  
  Octopus
- B.
  
  Shark
- C.
  
  Starfish
- D.
  
  Crocodile
Correct Answer
D. Crocodile

Explanation
Crocodile is the correct answer because crocodiles are primarily found in freshwater habitats such as rivers, lakes, and swamps. They are not adapted for life in saltwater environments like oceans. Octopuses, sharks, and starfish, on the other hand, can all be found in oceans.

Which of these is the origin of oceans?
- A.
  
  Rocks
- B.
  
  Rainfall
- C.
  
  Fishes
- D.
  
  None of the above
Correct Answer
D. None of the above

Explanation
The correct answer is "None of the above". This is because the origin of oceans is not rocks, rainfall, or fishes. Oceans are believed to have formed through a process called "outgassing" where water vapor and other gases were released from the Earth's interior through volcanic activity. Over time, these gases condensed and formed the vast bodies of water we now know as oceans.

Which of these parts of the earth is not covered by ocean?
- A.
  
  Biosphere
- B.
  
  Hydrosphere
- C.
  
  Lithosphere
- D.
  
  Atmosphere
Correct Answer
C. LithospHere

Explanation
The lithosphere is the solid outer layer of the Earth, which includes the crust and the uppermost part of the mantle. It is composed of rocks and minerals and is not covered by ocean. The hydrosphere refers to all the water on Earth, including oceans, lakes, rivers, and groundwater. The biosphere refers to all living organisms on Earth. The atmosphere is the layer of gases surrounding the Earth.
