The Formation Of The Earth
Science Quiz
- 1.
How did the earth change shape
- A.
It changed when a meteor crashed into earth
- B.
Earth Got older and gravity crushed rock and the planet became round
- C.
It got hit by a comet and it turned the earth round
Correct Answer
B. Earth Got older and gravity crushed rock and the planet became roundExplanation
As the Earth aged, gravity caused the rocks on its surface to be crushed, leading to the planet becoming round. Over time, the force of gravity acting on the Earth's mass caused the rocks to settle and form a more spherical shape.Rate this question:

How did Photosynthesis contribute to Earths current atmosphere?
- A.
Ultraviolet Radiation that causes sunburns
- B.
During the proccess of making food organisms created oxygen
- C.
Is the proccess of absorbing carbon dioxide from the atmosphere to make food
Correct Answer
B. During the proccess of making food organisms created oxygenExplanation
During the process of photosynthesis, organisms that make food also produce oxygen. This oxygen has accumulated over billions of years and contributed to the current atmosphere of Earth.Rate this question:

Earths First Atmosphere was mostly made of
- A.
Nitrogen and oxygen
- B.
Chlorine,nitrogen, and sulfur
- C.
Carbon dioxide and water vapor
Correct Answer
A. Nitrogen and oxygenExplanation
The correct answer is nitrogen and oxygen. This is because nitrogen and oxygen are the two most abundant gases in Earth's current atmosphere. Nitrogen makes up about 78% of the atmosphere, while oxygen makes up about 21%. These gases were also present in Earth's first atmosphere, as they were released from volcanic activity and the outgassing of the early Earth's interior. Other gases like carbon dioxide and water vapor were also present, but in smaller amounts compared to nitrogen and oxygen.Rate this question:

How did oceans form
- A.
Rain collected over time and rained for about 4 million years
- B.
Molecules in the air were broken
- C.
Water falls
Correct Answer
A. Rain collected over time and rained for about 4 million yearsExplanation
The answer states that oceans formed through the process of rain collecting over time and raining for about 4 million years. This explanation suggests that the accumulation of rainwater over an extended period led to the formation of large bodies of water, eventually resulting in the formation of oceans.Rate this question:

How did life form
- A.
UV Radiation
- B.
Photosynthesis
- C.
Trees
Correct Answer
A. UV RadiationExplanation
UV radiation is a possible explanation for the formation of life because it is believed that early Earth was exposed to high levels of UV radiation from the Sun. This UV radiation could have played a role in the chemical reactions that led to the formation of organic molecules, which are the building blocks of life. Additionally, UV radiation can also cause mutations in DNA, leading to genetic diversity and the evolution of life. Therefore, UV radiation is considered as one of the potential factors that contributed to the origin and development of life on Earth.Rate this question:
