Earth Spheres Quiz For 8th Grade
The earth is a system majorly consists of four interacting components. The earth's elements move within and between these components. They are Lithosphere, Atmosphere, Hydrosphere, and Biosphere. Test your 8th grader's knowledge of the earth's system and the interaction between these four spheres.
- 1.
_____ contains all living things on earth
- A.
Biosphere
- B.
Atmosphere
- C.
Hydrosphere
- D.
Lithosphere
Correct Answer
A. BiospHereExplanation
The biosphere refers to the part of the Earth where all living organisms exist. It includes all ecosystems and habitats, from the deepest oceans to the highest mountains. The biosphere is made up of various biomes, such as forests, grasslands, and deserts, which support a diverse range of plant and animal life. It is responsible for sustaining life on Earth by providing essential resources and maintaining the balance of ecosystems.Rate this question:

The Biosphere is sometimes referred to as _____
- A.
Atmosphere
- B.
Hydrosphere
- C.
Ecosphere
- D.
Lithosphere
Correct Answer
C. EcospHereExplanation
The Biosphere is sometimes referred to as the Ecosphere because it encompasses all the living organisms and their interactions with the environment on Earth. It includes all ecosystems, such as forests, oceans, deserts, and grasslands, where life exists. The term "Ecosphere" emphasizes the interconnectedness and interdependence of all living things within the biosphere.Rate this question:

Who coined the term Biosphere in 1875?
- A.
Louis Pasteur
- B.
Isaac Newton
- C.
Benjamin Franklin
- D.
Eduard Suess
Correct Answer
D. Eduard SuessExplanation
Eduard Suess is credited with coining the term "Biosphere" in 1875. He was an Austrian geologist who proposed the concept of the biosphere as the zone of life on Earth, encompassing all living organisms and their interactions with the environment. Suess's work on the biosphere contributed to the understanding of the Earth's interconnected ecosystems and the delicate balance of life within them.Rate this question:

Lithosphere is derived from the Greek words Litho and Sphaira which mean _____ and _____
- A.
Sphere and Rocky
- B.
Rocky and Sphere
- C.
Ground and Sphere
- D.
Environment and Sand
Correct Answer
B. Rocky and SpHereExplanation
The correct answer is "Rocky and Sphere". The word "litho" in Greek means "rock" or "stone", while "sphaira" means "sphere" or "ball". Therefore, the term "lithosphere" refers to the outermost layer of the Earth, which is composed of solid rocks and forms a spherical shape.Rate this question:

Who coined the term Lithosphere?
- A.
Eduard Suess
- B.
Louis Pasteur
- C.
Joseph Barrell
- D.
Benjamin Franklin
Correct Answer
C. JosepH BarrellExplanation
Joseph Barrell is credited with coining the term "Lithosphere." He was an American geologist who proposed the concept of the lithosphere in the early 20th century. The lithosphere refers to the rigid outer layer of the Earth, including the crust and uppermost part of the mantle. Barrell's contribution to the understanding of Earth's structure and the development of geological concepts makes him the most likely candidate to have coined the term.Rate this question:

From where do we extract natural resources like coal?
- A.
Hydrosphere
- B.
Biosphere
- C.
Lithosphere
- D.
Ecosphere
Correct Answer
C. LithospHereExplanation
Coal is extracted from the lithosphere. The lithosphere refers to the solid outer layer of the Earth, which includes the crust and uppermost part of the mantle. Coal is formed from the remains of plants that lived and died millions of years ago. Over time, these plant remains were buried and subjected to heat and pressure, resulting in the formation of coal. As coal is a fossil fuel, it is found in the lithosphere, specifically in underground coal mines.Rate this question:

The frozen part of the hydrosphere is called _____
- A.
Cryosphere
- B.
Athenosphere
- C.
Ecosphere
- D.
Lithosphere
Correct Answer
A. CryospHereExplanation
The correct answer is Cryosphere. The cryosphere refers to the frozen part of the hydrosphere, which includes ice caps, glaciers, snow, and permafrost. It plays a crucial role in regulating Earth's climate and is affected by global warming. The other options, Athenosphere, Ecosphere, and Lithosphere, do not specifically refer to the frozen part of the hydrosphere.Rate this question:

The hydro, used to coin the word hydrosphere means _____
- A.
Water
- B.
Seas
- C.
Fluid
- D.
Flow
Correct Answer
A. WaterExplanation
The term "hydro" in the word "hydrosphere" is derived from the Greek word for water. Therefore, the correct answer is water.Rate this question:

The atmosphere layer closest to earth is referred to _____
- A.
Cryosphere
- B.
Ecosphere
- C.
Troposphere
- D.
Athenosphere
Correct Answer
C. TropospHereExplanation
The correct answer is Troposphere. The troposphere is the lowest layer of the Earth's atmosphere, extending from the Earth's surface up to an average height of about 8-15 kilometers. It is where weather phenomena occur, such as clouds, precipitation, and wind. This layer contains the majority of the Earth's atmospheric mass and is where most of the Earth's weather occurs. The other options, Cryosphere, Ecosphere, and Athenosphere, refer to different aspects of the Earth's systems but are not specifically related to the atmospheric layer closest to the Earth.Rate this question:

Which of the following elements makes up 78% of the atmosphere?
- A.
Oxygen
- B.
Carbon dioxide
- C.
Nitrogen
- D.
Helium
Correct Answer
C. NitrogenExplanation
Nitrogen makes up 78% of the atmosphere. This is because nitrogen is a highly abundant element and is present in the air we breathe. It is an essential component of proteins and nucleic acids and plays a crucial role in supporting life on Earth. Oxygen is the second most abundant element in the atmosphere, but it only makes up about 21%. Carbon dioxide and helium are present in much smaller quantities and do not contribute significantly to the composition of the atmosphere.Rate this question:
