text: The difference in speed from earth to venus is that sometimes we are closer to mars and other times to venus is close to earth. A negavtive reason Venus has a thick atomosphere of almost 97 perecent carbon dioxide blankets venus. Another challange is that that the clouds of highly corrosive sulfuric acid in venus atomshere. The conditions are far more extreme than anything humans encounter on Earth. Thrid reason Venus has the hottest surface temperture of any planet in our planet ,even though Mercury is closer to our sun. The dangers ir presents is the high pressure and heat,venus geology and weather present additionl impediments like erupting volcanoes,powerful earthquakes and frequent lighting. A reason why humanity is exploring venus because it once have been earth like planet in our planet. A long time ago Venus was probably covered largely with oceans and could have supported various forms of life. This shows the dangers Venus has and the if it worthly to discovered.Dear Mr. Principal,
