Questions and Answers

1.

What would be the best example of a body of water that contains saltwater?
- A.
  
  Mississipi River
- B.
  
  Lake Ontario
- C.
  
  Pacific Ocean
- D.
  
  Pond
Correct Answer
C. Pacific Ocean

Explanation
The Pacific Ocean is the best example of a body of water that contains saltwater. It is the largest and deepest ocean on Earth and covers a vast area, containing a high concentration of salt. The presence of saltwater in the Pacific Ocean is due to various factors such as the dissolution of minerals from rocks, volcanic activity, and the continuous input of salt from rivers and streams that flow into it.

Which of these animals lives mostly in fresh water?
- A.
  
  Frog
- B.
  
  Penguin
- C.
  
  Shark
- D.
  
  Whale
Correct Answer
A. Frog

Explanation
Frogs are amphibians that typically live in freshwater habitats such as ponds, lakes, and streams. They have specialized adaptations like permeable skin and webbed feet that allow them to thrive in these environments. Penguins, sharks, and whales, on the other hand, are marine animals that primarily live in saltwater habitats. Penguins inhabit the cold waters of the Southern Hemisphere, sharks are found in oceans around the world, and whales are large marine mammals that inhabit oceans and seas. Therefore, the correct answer is Frog.

3.

What type of water is in lakes and rivers?
- A.
  
  Green
- B.
  
  Salty
- C.
  
  Brown
- D.
  
  Fresh
Correct Answer
D. Fresh

Explanation
Lakes and rivers typically contain fresh water. Fresh water refers to water that does not contain a significant amount of salt or other minerals. This type of water is essential for various organisms and ecosystems that rely on it for drinking, irrigation, and other purposes.

What is the majority of Earth covered with?
- A.
  
  Land
- B.
  
  Water
- C.
  
  Mountains
- D.
  
  Rivers and lakes
Correct Answer
B. Water

Explanation
The majority of Earth is covered with water. This is supported by the fact that approximately 71% of the Earth's surface is covered by oceans, seas, and other bodies of water. Water plays a crucial role in the Earth's climate, weather patterns, and the existence of various ecosystems. Additionally, the presence of water is essential for the survival of all living organisms on the planet.

5.

What type of water makes up the ocean?
- A.
  
  Salty
- B.
  
  Fresh
- C.
  
  Green
- D.
  
  Crystal clear
Correct Answer
A. Salty

Explanation
The correct answer is salty because the ocean is made up of saltwater. This is due to the presence of dissolved salts, such as sodium chloride, in the water. The salt content of the ocean is approximately 3.5%, making it significantly saltier than freshwater sources like rivers and lakes. This salinity is maintained through various processes, including the weathering of rocks, volcanic activity, and the continuous input of salts from rivers and streams.

What are large frozen blocks of ice called usually found near the poles?
- A.
  
  Icebergs
- B.
  
  Glaciers
- C.
  
  Ice cubes
- D.
  
  Oceans
Correct Answer
B. Glaciers

Explanation
Glaciers are large frozen blocks of ice that are usually found near the poles. They are formed over many years from compacted snow and ice, and can be massive in size, sometimes spanning hundreds of square miles. Unlike icebergs, which are chunks of ice that break off from glaciers and float in the ocean, glaciers are stationary and can shape the landscape around them through erosion and deposition of sediment. Therefore, glaciers are the correct answer for large frozen blocks of ice found near the poles.

Rate this question:
7.

What of these materiales could NOT be recycled?
- A.
  
  Glass
- B.
  
  Paper
- C.
  
  Metal
- D.
  
  Smelly trash
Correct Answer
D. Smelly trash

Explanation
Smelly trash cannot be recycled because it is a mixture of different types of waste, including organic matter, which cannot be processed in recycling facilities. Recycling typically involves separating and processing specific materials like glass, paper, and metal, which can be transformed into new products. Smelly trash, on the other hand, needs to be disposed of properly through waste management systems, such as composting or landfill.

What is the Sun made of?
- A.
  
  Rocks and lava
- B.
  
  Glowing gases
- C.
  
  Light
- D.
  
  Cosmic dust
Correct Answer
B. Glowing gases

Explanation
The Sun is made up of glowing gases. These gases, primarily hydrogen and helium, undergo nuclear fusion in its core, releasing immense amounts of energy in the form of light and heat. This process, known as thermonuclear fusion, is what powers the Sun and allows it to emit light and heat. Therefore, the correct answer is glowing gases.

9.

What of these you cannot see in the night sky?
- A.
  
  The Moon
- B.
  
  Stars
- C.
  
  Shooting stars
- D.
  
  The Sun
Correct Answer
D. The Sun

Explanation
The Sun cannot be seen in the night sky because it is the source of light during the day. At night, the Earth is facing away from the Sun, causing it to be below the horizon. This absence of sunlight makes the sky appear dark, allowing us to see the Moon, stars, and occasionally shooting stars. However, the Sun can be seen during sunrise and sunset when it is close to the horizon, creating a beautiful display of colors in the sky.
