Question 45

The term 'Goldilocks Zone' is often seen in the news in the context of

AOptions

A) the limits of habitable zone above the surface of the Earth

B) regions inside the Earth where shale gas is available

C) search for the Earth-like planets in outer space

D) search for meteorites containing precious metals

BSolution

The term 'Goldilocks Zone' is frequently used in astrophysics and exoplanetary science. It refers to the habitable zone around a star where conditions are 'just right' for liquid water to exist on a planet's surface. This means the planet is neither too close to its star (where water would evaporate) nor too far (where water would freeze). Liquid water is considered a fundamental requirement for life as we know it. Therefore, the concept of the Goldilocks Zone is central to the ongoing search for Earth-like planets in outer space that could potentially harbor extraterrestrial life.

CStrategy

For scientific terms appearing in the news or general knowledge, understand their core meaning and the field of science they relate to. Contextual clues in the options often help in narrowing down the correct answer by associating the term with its relevant scientific domain.
