All of the living quarters, equipment, supplies, and vehicles used to protect astronauts and allow them to live and work in space are called
Correct Answer
C. Accommodations
Explanation
Accommodations refers to all the living quarters, equipment, supplies, and vehicles that are used to protect astronauts and enable them to live and work in space. This includes everything from the living modules and sleeping quarters to the necessary supplies and vehicles for transportation. The term "accommodations" encompasses the entire infrastructure and resources required to support astronauts during their time in space.

Astronauts wear thick gloves when they perform space walks outside the space station. The gloves provide protection against -
Correct Answer
D. Low temperatures
Explanation
Astronauts wear thick gloves when they perform space walks outside the space station to protect themselves from low temperatures. In the vacuum of space, temperatures can drop to extreme lows, which can be dangerous for the astronauts. The thick gloves act as insulation, preventing heat loss from their hands and ensuring that they can safely carry out their tasks without suffering from the cold temperatures.
3.
Spacesuits have layers that have high capacity for thermal insulation to help-
Correct Answer
A. Regulate body temperature and pressure differences in the extremes of space
Explanation
Spacesuits have layers that provide thermal insulation to regulate body temperature and pressure differences in the extremes of space. In space, temperatures can vary significantly, from extremely cold to extremely hot. The layers of the spacesuit help to maintain a stable body temperature by preventing heat loss or gain. Additionally, the pressure inside a spacesuit needs to be regulated to protect the astronaut from the vacuum of space. The layers of the spacesuit help to maintain the necessary pressure levels to ensure the astronaut's safety and comfort.

What design element of the International Space Station protects astronauts from micro-meteoroids, which are tiny bits of space debris travelling at high speeds?
Correct Answer
D. Tough outer shell
Explanation
The tough outer shell of the International Space Station is designed to protect astronauts from micro-meteoroids, which are tiny bits of space debris traveling at high speeds. This outer shell acts as a barrier, absorbing and dispersing the impact energy of these small particles, preventing them from penetrating the station and potentially causing harm to the astronauts inside.
5.
In micro-gravity tools and supplies float around in a space craft, what accommodation helps to prevent this?
Correct Answer
C. Velcro tie downs and straps
Explanation
In micro-gravity, the lack of gravity causes objects to float around in a spacecraft. To prevent this, velcro tie downs and straps are used to secure tools and supplies in place. Velcro provides a strong grip, allowing items to be fastened securely to walls or surfaces. This helps to ensure that essential equipment and resources are easily accessible and do not pose a danger by floating freely in the spacecraft.

Large amounts of water is heavy and takes up a lot of room on a space station, what accommodation is used to maximize room while still having enough water for astronauts to drink
Correct Answer
B. Water is recycled from urine and evaporation
Explanation
In order to maximize room on a space station while still providing enough water for astronauts to drink, the water is recycled from urine and evaporation. This allows the crew to reuse the water instead of having to store large amounts of fresh water, which would take up a significant amount of space and add unnecessary weight to the station. By recycling water, the astronauts can have a sustainable source of drinking water while minimizing the space and weight requirements.
7.
Which of the following would have the greatest gravitational attraction between the two masses?
Correct Answer
B. Option 2
Explanation
Option 1 would have the greatest gravitational attraction between the two masses because gravitational attraction is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. Since no information is provided about the masses or distances, we can assume that Option 1 has the largest masses or the smallest distance between them, resulting in the greatest gravitational attraction.
8.
The habitable zone is the distance from a star that best allows life to exist on a planet. In the solar system below, the habitable zone is between 60 and 90 million km from the star. Which of these planets has the best chance of supporting life?
Correct Answer
B. Planet X
Explanation
Planet X has the best chance of supporting life because it is located within the habitable zone, which is the distance from a star that best allows life to exist on a planet.
