Why is Earth capable of sustaining life while Mars is not?

• Mars is in the habitable zone, but it is a bit smaller than earth,

  making it impossible to support life.

• Mars is in the habitable zone, but made of gas instead of rock, making it impossible to support life.

• Mars is in the habitable zone, but is a bit further from the sun than earth, making it too cold to support life.

• Mars is in the habitable zone, but it is a bit further from the sun than earth, making it too hot to support life.

What characteristics of a planet will influence whether its temp. will be suitable to life?

• The amount of its gravitational force

• The number and size of active volcanoes

• The tilt of the axis of rotation of the planet

• The distance from the Sun of its orbit

Define habitable zone.

• a vehicle propelled by the exhaust made from burning fuel

• an area that is just the right distance from the sun, or other star, that it is not too hot or too cold to support life

• matter that contains carbon which includes all living things

• the study of the origin, development, distribution, and future of life on Earth and in the universe

Earth appears to be the only body in the solar system that can support life. Which of the following are unique characteristics of the Earth that allow life to exist?

• all of these

• the composition of Earth's atmosphere

• Earth's distance from the Sun

Earth is the only planet that is known to support life. Almost two-thirds of Earth's surface is covered with water. It has a rocky terrain consisting of deep valleys and high mountains. Earth is neither too far nor too near to the Sun. This ensures that there is enough sunlight to maintain moderate temperatures on Earth. Which three factors would be most important for a body in the Solar System outside of Earth to support life?

• water, moderate temperatures, and sunlight

• water, mountains, and soil

• hydrogen, moderate temperatures, and carbon dioxide

• carbon dioxide, moderate temperatures, and soil

Titan is one of the moons of Saturn. It has a thick atmosphere rich in organic compounds. The image shows a lake and channels on the surface of Titan. Titan is one of the coldest places in the solar system. Its lakes are probably made of methane, the main ingredient in natural gas, which is a liquid at low temperatures. Unexpected chemical reactions taking place on Titan have led some scientists to hypothesize that life may have evolved there. How would finding life on Titan change scientific ideas about what conditions are necessary to support life?

• It would prove that liquid water is not necessary for life.

• It would prove that nutrients are not necessary for life.

• It would prove that a source of energy is not necessary for life.

• all of these
