Explanation

• In space exploration, a spectroscope is typically used to analyze the light coming from stars, planets, and other celestial objects to determine their chemical composition.
• This helps scientists understand the formation and evolution of stars, planets, and galaxies.

Explanation

• The greenhouse effect refers to the way certain gases in the Earth's atmosphere.
• Such as carbon dioxide, methane, and water vapor, trap heat from the sun, keeping the planet warm enough to support life.
