What Do You Know About Earth And Space Science?
Earth and space science deal with the connection of systems. It can also be defined as the interconnections between the ocean, land, activities taking place at the earth, as well as the land. I am sure you are willing to learn more about this, and in view of that, practice the short quiz highlighted below.

What are the decomposing features of the earth surface?
- A.
Rock particles
- B.
Tectonic particles
- C.
Water particles
- D.
Wind
Correct Answer
B. Tectonic particlesExplanation
The decomposing features of the earth's surface refer to the processes that break down and reshape the land. Rock particles are not decomposing features themselves but rather the result of the decomposition process. Water particles and wind are also not decomposing features but rather agents that contribute to the erosion and transportation of materials. Tectonic particles, on the other hand, are directly involved in the decomposition of the earth's surface through processes such as faulting, folding, and volcanic activity.Rate this question:

When was Pluto declared as a dwarf planet?
- A.
2006
- B.
2007
- C.
2008
- D.
2009
Correct Answer
A. 2006Explanation
Pluto was declared as a dwarf planet in 2006. This decision was made by the International Astronomical Union (IAU) during their General Assembly. Prior to this, Pluto was classified as the ninth planet in our solar system. However, the IAU redefined the criteria for what constitutes a planet, leading to the reclassification of Pluto as a dwarf planet. This decision was based on the fact that Pluto did not meet the newly established criteria, particularly its failure to clear its orbit of other debris.Rate this question:

Which of the following is NOT a discovery made in space?
- A.
Thompson's plum pudding model
- B.
Rutherford's nuclear model
- C.
Thomas Edison space research
- D.
Quantum mechanical model
Correct Answer
C. Thomas Edison space researchExplanation
The correct answer is Thomas Edison space research. Thomas Edison was a renowned inventor and businessman, but he did not make any discoveries in space. His contributions were primarily in the field of electrical engineering and the development of various inventions, such as the phonograph and the incandescent light bulb.Rate this question:

How many dynamically-interconnected spheres are on the earth surface?
- A.
2
- B.
3
- C.
4
- D.
5
Correct Answer
C. 4Explanation
There are four main layers that make up the Earth's surface: the lithosphere, hydrosphere, atmosphere, and biosphere. These layers are dynamically interconnected and interact with each other. The lithosphere refers to the solid outer layer of the Earth, which includes the crust and uppermost part of the mantle. The hydrosphere includes all of the Earth's water, such as oceans, lakes, and rivers. The atmosphere is the layer of gases that surrounds the Earth. And finally, the biosphere is the part of the Earth where living organisms exist. Therefore, there are four dynamically-interconnected spheres on the Earth's surface.Rate this question:

What does hydrosphere represent?
- A.
Solid, liquid and gaseous water
- B.
Solid and liquid water
- C.
Liquid and gaseous water
- D.
Gaseous water
Correct Answer
A. Solid, liquid and gaseous waterExplanation
The hydrosphere represents all forms of water on Earth, including solid, liquid, and gaseous states. This includes water in the form of ice, liquid water in rivers, lakes, and oceans, as well as water vapor in the atmosphere.Rate this question:

Which of the following is NOT a field of astronomy defined by approach?
- A.
Professional astronomy
- B.
Astrometry
- C.
Observational astronomy
- D.
Amateur astronomy
Correct Answer
A. Professional astronomyExplanation
Professional astronomy is not a field of astronomy defined by approach because it refers to the study of celestial objects and phenomena by professional astronomers who are trained and employed in the field. The other options, astrometry, observational astronomy, and amateur astronomy, all involve different approaches to studying and observing celestial objects and phenomena.Rate this question:

Which of the following is NOT a field of astronomy defined by scope?
- A.
Astrophysics
- B.
Space astronomy
- C.
Stellar astronomy
- D.
Galactic astronomy
Correct Answer
B. Space astronomyExplanation
Space astronomy is not a field of astronomy defined by scope. While astrophysics, stellar astronomy, and galactic astronomy all focus on specific areas within astronomy, space astronomy is a broad term that encompasses all aspects of astronomy that take place outside of Earth's atmosphere. It includes the study of celestial objects and phenomena using satellites, space probes, and telescopes located in space. Therefore, space astronomy is not a defined field within astronomy, but rather a term that encompasses various subfields.Rate this question:

What does aerospace comprise of?
- A.
The surrounding space
- B.
The earth surface
- C.
The moon, the sun and other planets
- D.
The earth's atmosphere and the surrounding space
Correct Answer
D. The earth's atmospHere and the surrounding spaceExplanation
Aerospace comprises of the earth's atmosphere and the surrounding space. This includes everything from the air we breathe to the vast expanse of outer space. It encompasses the study and exploration of both the Earth's atmosphere and celestial bodies beyond our planet, such as the moon, the sun, and other planets.Rate this question:
