Space proximity & accommodations

A scientist is analyzing images of an object in the solar system. Which features in the images would cause the scientist to hypothesize that the object might be able to support life?

• channels that indicate flowing water

• craters that indicate collisions with meteoroids

• poles that indicate a magnetic field

• ridges that indicate tectonic activity

The diagram shows the parts of a space suit. Which correctly explains the function of a space suit part?

• The helmet and solar visors are needed because noise is loud in space.

• The gloves are needed to prevent injury while operating equipment on the spacecraft.

• The liquid cooling and ventilation garment is needed because temperatures can be high when facing the sun.

• The primary life support subsystem is needed because there are pockets of oxygen-deficient air in space.

The table below shows characteristics of objects in the solar system. Which object would interest a scientist most in terms of characteristics necessary to support life?

• Object A because it has geysers and organic compounds.

• Object B because it has no atmosphere and is close to the sun.

• Object C because it has a gaseous surface and is far from the sun.

• Object D because it has a rocky surface and an atmosphere.

Enceladus is a moon of Saturn that is mostly covered in ice. Astrobiologists theorize that Enceladus may have characteristics that allow it to support life. Which characteristics would allow a distant object, such as Enceladus, to be warm enough for liquid water to exist near its surface?

• An atmosphere made of oxygen, which traps energy from the Sun.

• A thin crust, so solar energy can easily penetrate the ice.

• An interior that experiences tidal heating because the object orbits a massive planet and has an eccentric object.

• An orbit that is eccentric, causing the object to approach the Sun during part of the year.

Identify which additional TWO actions would best prevent the spread of infectious diseases among astronauts in a spacecraft?

• sealing trash and used clothes in plastic bags

• taking cold medicine on a daily basis regardless of if the astronaut is sick

• exercising regularly to stay healthy

• wearing spacesuits while in the spacecraft

• eliminating microgravity by creating a gravitational pull within the spacecraft

Why is Mars not a viable option at this time to support life?

• Mars has no living organisms to sustain human life.

• Mars is ready to support life, just need a way to get there.

• Mars is best place to support life, but the atmosphere is made of too much methane and Mars is too far away.

• Mars is not able to support liquid water and lack of enough carbon dioxide to keep the temperature on the surface stable.

Habitable zones are the areas...

• where the planet orientations cause seasons

• around a star where water can be liquid

• where only planets the size of Earth can form

• where life is guaranteed to be found on planets

The four conditions that enable life on Earth are...

• Frozen water, liquid water, breathable gases, gravity

• Liquid water, gravity, atmosphere, temperature

• Liquid water, frozen water, seasons, atmosphere

• Breathable atmosphere, gravity, seasons, water

What happens if a planet is too hot?

• The water will be nice and warm

• The water will boil away

• The water will be too cold

• The water will freeze and make ice

A factor that allows Earth to support life is the planet's ozone layer. This ozone layer protects life on Earth by absorbing and blocking ultraviolet radiation, especially a form called (a)   . These harmful ultraviolet rays can cause ​ (b)   in humans and even cause damage to crops.

• UVB
• UVA
• UVharmful rays
• skin cancer
• stomach cancer
• eye cancer
