The exosphere of which planet is so thin that it gets constantly bombarded by solar activity?

• Venus

• Mars

• Mercury

• Earth

Answer explanation

Mercury has an extremely thin exosphere, making it vulnerable to constant solar activity. Unlike Venus, Mars, or Earth, its lack of a substantial atmosphere allows solar particles to bombard its surface directly.

Which planet's surface is toxic with sulfuric acid rain and winds?

• Venus

• Mars

• Mercury

• Earth
