Back

A spectroscope is a tool used to analyze the light spectrum emitted or absorbed by objects, helping to determine their composition.

Front

What force causes dust and gas in interstellar clouds to clump together?

Back

Gravity causes dust and gas in interstellar clouds to clump together.

Front

What is the difference between high tide and low tide?

Back

High tide is when the water level is at its peak, while low tide is when the water level is at its lowest.

Front

What is the role of gravity in the formation of stars?

Back

Gravity pulls together gas and dust in space, leading to the formation of stars as these materials clump and compress.
