Question

Difficulty: MediumTransitions: Cause and Effect

Which transition word or phrase best shows the causal link between the sun's solar winds and the composition of the inner planets?

Answer:In the early solar system, the proximity of the infant Sun generated intense solar winds that swept lighter gases like hydrogen and helium outward toward the colder, outer regions. 【Consequently】, the inner planets were left with a scarcity of volatile elements, forming primarily from dense, rocky materials that could withstand the solar radiation.

Answer

Consequently (or other cause-and-effect transitions such as 'therefore', 'thus', or 'as a result')
The correct answer must be a cause-and-effect transition. The first sentence describes how the early Sun's winds swept lighter gases away from the inner solar system, and the second sentence describes the direct result of this process (the rocky, volatile-poor composition of the inner planets). Transitions like 'consequently', 'therefore', 'thus', or 'as a result' logically connect these sentences by signaling that the second event occurred because of the first.

Step-by-Step Solution

1
Analyze the relationship between the first and second sentences.
The first sentence explains that the early Sun's solar winds blew light gases away from the inner solar system. The second sentence describes the outcome: the inner planets formed without these volatile elements and are composed primarily of rocky materials.
To choose the correct transition, we must understand how the two ideas are logically connected.
2
Identify the type of transition required.
The second sentence is a direct effect of the cause described in the first sentence. A cause-and-effect transition is needed.
The sweeping away of gases directly led to the rocky composition of the inner planets.
3
Select a transition word that establishes this cause-and-effect relationship.
Words such as 'consequently', 'therefore', 'thus', 'accordingly', or 'as a result' are appropriate cause-and-effect transitions.
These words successfully signal that the composition of the inner planets was a consequence of the solar winds.
