Exploring Venus: Earth's Fiery Sister Planet

Venus, often called Earth's sister planet due to its similar size, has a dense atmosphere mainly composed of carbon dioxide, nitrogen, and sulfuric acid droplets. This creates a greenhouse effect, leading to extreme surface temperatures that can melt lead. Various spacecraft have explored Venus, revealing its surface features like canyons and volcanoes. Interestingly, a day on Venus is longer than its year, taking 8 Earth months to rotate on its axis but only 7 months to orbit the sun.

What is the primary composition of Venus's atmosphere?

• Oxygen and hydrogen

• Carbon dioxide and nitrogen

• Methane and ammonia

• Helium and neon

What is the effect of Venus's thick clouds on its surface temperature?

• They cool the surface

• They have no effect

• They trap heat, causing high temperatures

• They reflect sunlight, reducing temperature

What happens to spacecraft that land on Venus?

• They operate for years

• They are quickly destroyed by the heat

• They return to Earth

• They become part of the landscape

Which of the following is a feature found on Venus's surface?

• Oceans

• Forests

• Ice caps

• Canyons and volcanoes

How does the length of a day on Venus compare to its year?

• A day is the same length as a year

• A day is longer than a year

• A day and a year are unrelated

• A day is shorter than a year
