Question

You have learned about many unique qualities of Earth, but how different is it from other planets? We know that it's different enough to do one thing that all the other planets cannot, and that is to support life. Some of the reasons why there's life on Earth is because of special conditions that other planets either don't have at all or have but not at a level that's able to support life. For this project, you'll make a chart of some of the basic characteristics of each planet so that you can compare and contrast these characteristics to those of Earth. OBJECTIVES Compare and contrast factors essential to life on Earth to conditions on other planets. Directions Use the library or Internet to research each planet. Make a chart comparing the following: approximate surface temperature relative surface gravity compared to Earth atmospheric gases water in any form: solid, gas, or liquid When you have completed your chart, use the information you have collected to answer the following questions: Which is the hottest planet? Which is the coldest planet? Which planet's temperature is closest to that of Earth? (Note: Water boils at 100°C/212°F. Water freezes at 0°C/32°F) Which planet has the greatest gravitational attraction? Which planet has the least gravitational attraction? Which planet's gravitational pull is closest to that of Earth? Do any of the planets have oxygen in their atmosphere? Which planet's atmosphere most resembles that of Earth? Do any of the planets have flowing water? Which planet's water resources (solid, gas, or liquid) might be close to the amount on Earth? Which planet most resembles Earth in terms of all of the factors: temperature, gravity, atmosphere, and water? If Earth became an uninhabitable planet, which planet do you think would be the next best to live on? Explain your answer.

Answer 1

Answer:

Jupiter:

approximate surface temperature: -234 degrees fahrenheit

relative surface gravity compared to Earth: 2.4 times that of the earth

atmospheric gases: hydrogen gas and helium gas

water in any form: solid, gas, or liquid: 0.25% in the atmosphere

Which is the hottest planet?

Venus

Which is the coldest planet?

pluto or uranus

Which planet's temperature is closest to that of Earth?

Mars

Which planet has the greatest gravitational attraction?

Jupiter

Which planet has the least gravitational attraction?

Mercury

Which planet's gravitational pull is closest to that of Earth?

Venus

Do any of the planets have oxygen in their atmosphere?

Mercury, mars, and jupiter

Which planet's atmosphere most resembles that of Earth?

Mars

Do any of the planets have flowing water?

Just Earth

Which planet's water resources (solid, gas, or liquid) might be close to the amount on Earth?

None of them

Which planet most resembles Earth in terms of all of the factors: temperature, gravity, atmosphere, and water?

Mars

If Earth became an uninhabitable planet, which planet do you think would be the next best to live on? Explain your answer.:

Mars. Because it is closest to earths standards and factors.
