What is the solid part of the earth called?
Correct Answer
B. LithospHereÂ
Explanation
The solid part of the earth is called the lithosphere. It is the outermost layer of the earth's surface and includes the crust and uppermost part of the mantle. The lithosphere is composed of solid rocks and minerals and is divided into several tectonic plates. It is where all landforms, such as mountains, valleys, and plains, are found. The lithosphere also plays a crucial role in supporting life on earth, as it provides a stable foundation for the biosphere.
2.
What is the part of the earth occupied by water called?
Correct Answer
B. HydrospHereÂ
Explanation
The part of the earth occupied by water is called the hydrosphere. This includes all the water on the planet, including oceans, seas, lakes, rivers, and even underground water. The hydrosphere is an essential component of the earth's system and plays a crucial role in regulating climate, supporting life, and shaping the planet's surface through erosion and deposition processes.
3.
What is the part of the earth composed of air called?
Correct Answer
C. AtmospHereÂ
Explanation
The part of the earth composed of air is called the atmosphere. It is the layer of gases that surrounds the planet and is held in place by gravity. The atmosphere is essential for supporting life on earth as it provides oxygen for breathing, regulates temperature, and protects us from harmful radiation from the sun.
4.
Which of these accounts for about 70 percent of the earth?
Correct Answer
B. HydrospHereÂ
Explanation
The hydrosphere is the correct answer because it accounts for about 70 percent of the earth. The hydrosphere includes all of the water on earth, including oceans, seas, lakes, rivers, and groundwater. This vast amount of water makes up a significant portion of the earth's surface, and it plays a crucial role in regulating the planet's climate, supporting various ecosystems, and providing a habitat for numerous species.
5.
Which of these serves as the habitat for fishes and sea animals?
Correct Answer
D. HydrospHereÂ
Explanation
The hydrosphere serves as the habitat for fishes and sea animals. The hydrosphere refers to all the water on Earth, including oceans, seas, rivers, lakes, and other bodies of water. These water bodies provide the necessary environment for fishes and sea animals to live and thrive. They provide food, shelter, and the right conditions for these organisms to survive.
6.
Which of these serves as habitat for birds of the air?
Correct Answer
C. AtmospHereÂ
Explanation
The correct answer is the atmosphere. The atmosphere is the layer of gases that surrounds the Earth and provides habitat for birds of the air. Birds live and fly within the atmosphere, using it for navigation, migration, and finding food and shelter. The atmosphere also provides birds with the necessary oxygen they need to breathe.
7.
What part of the earth supports living organisms?
Correct Answer
B. BiospHereÂ
Explanation
The biosphere is the part of the earth that supports living organisms. It includes all the regions of the earth where life exists, including the surface of the land, bodies of water, and the atmosphere. The biosphere is made up of a complex web of interactions between living organisms and their environment. It is where organisms find the necessary resources, such as food, water, and shelter, to survive and reproduce. The biosphere is crucial for the existence and sustainability of life on earth.
8.
Which of these planets is the farthest to the sun?
Correct Answer
D. Pluto
Explanation
Pluto is the farthest planet from the sun compared to the other options given. Despite being reclassified as a dwarf planet, it still orbits the sun at a greater distance than any of the other listed planets.
9.
Which of these planets is the biggest?
Correct Answer
D. JupiterÂ
Explanation
Jupiter is the correct answer because it is the largest planet in our solar system. It has a diameter of about 86,881 miles, making it more than 11 times wider than Earth. Jupiter's massive size is due to its strong gravitational pull, allowing it to gather and retain a large amount of gas and other materials. Its immense size also contributes to its distinct features, such as the Great Red Spot, a massive storm that has been raging for centuries.
10.
Which of these planets is the hottest?
Correct Answer
D. Mercury
Explanation
Mercury is the correct answer because it is the closest planet to the sun, resulting in extreme temperatures. During the day, the surface temperature on Mercury can reach up to 800 degrees Fahrenheit (430 degrees Celsius), making it the hottest planet in our solar system.
