Solar System

All of the following are ways that the atmosphere makes the existence of life on Earth possible EXCEPT —

• maintains a constant temperature

• shields Earth from small collisions

• offers protection from radiation

• allows for gas exchange between plants and animals

Scientists have determined that there is a particular distance from the Sun that is most likely to allow life to inhabit a planet. This area is called the inhabitable zone and is shaded in the diagram below. Also, the planet needs liquid water and oxygen present.

According to the information above, why would Planet E NOT be a good place to look for life?

• Too Hot

• No Oxygen

• Too Cold

• No Water

The table shows characteristics of planets in our solar system.

Which planet could most likely support human life?

• Planet A

• Planet B

• Planet C

• Planet D

Which of the following characteristics of the Sun helps life to exist on Earth?

1.The Sun’s gravity keeps the Earth in a consistent orbit.

2.The Sun’s radiation provides heat to the Earth.

3.The Sun’s light shines on half of the Earth at a time.

4.The Sun’s solar flares and storms shower the Earth with additional radiation.

5.The Sun’s spots cause cooler areas on the Sun’s surface.

6. The Sun’s position in relation to the Earth and Moon causes eclipses.

• Characteristics 1, 2, and 3

• Characteristics 2 and 3

• Characteristics 2, 3, 4, and 5

• Characteristics 3, 5, and 6

Why would life on Earth be unlikely to survive if the liquid iron core did not produce a magnetic field?

• Oxygen would not be attracted to the lower atmosphere, which would not allow for respiration.

• Asteroids would not be repelled, which would cause constant explosions on the surface.

• The Sun’s heat would not be attracted, which would make the surface too cold.

• The radiation from the Sun would not be repelled, which would make the surface too hot.

Which of the following characteristics of the Earth are essential to the existence of life?

1.Earth’s size causes acceleration due to gravity to be 9.8 m/s^2.

2.Earth’s atmosphere is composed of mostly nitrogen with oxygen and carbon dioxide.

3.Earth’s surface has an abundance of silicon oxide in the form of sand.                            

4.Earth’s surface temperature ranges from -88°C to 58°C.

5.Earth’s magnetic field repels some solar radiation from reaching the surface.

• Characteristics 1, 2, and 4

• Characteristics 2, 4, and 5

• Characteristics 1 and 3
