Which of the following is the strongest reason for Earth being habitable?

• The Earth is close enough to the Sun to have a night and day.
• The atmosphere of Earth has a favorable ratio of gases.
• The Earth is far enough from the Sun to be protected from radiation.
• The atmosphere is thin enough to allow energy to pass through it.

What features make a planet habitable?

• Oxygen, Water, Proximity to the Sun and Food
• Carbon Dioxide, Proximity to the Sun, Habitat and artificial satelites
• Lots of radiation, extreme temperatures, no food, no shelter
• Extreme sunlight, dangerous predators, and salty water

One of the conditions for life as we know it on Earth is a temperature range of 

• 0 to 100 degrees Fahrenheit
• 0 to 100 degrees Celsius
• 0 to 100 degrees Kelvin
• 32 to 100 degrees Fahrenheit

The atmosphere on Venus is extremely hot due to the large percentage of ___________ . 

• atmospheric carbon dioxide 
• terresterial carbon dioxide
• water vapor
• terresterial oxygen

Earth's tilt contributes to habitability 

• by moderating temperatures. 
• by creating hot and cold zones. 
• by promoting weather patterns to support the water cycle. 
• by keeping the earth the same distance from the sun.

Why does Venus have such high surface temperatures?  

• due to a run-away green house effect from high levels of carbon dioxide.
• because its orbit is near the Sun. 
• due to the internal heat of the planet's core. 
• due to high energy levels from the planet's original formation.
