Test: Sunita In Space - 1 - Class 5 MCQ

• In space, there is no gravity, so objects, including hair, don't fall due to gravity like on Earth.
• Without gravity pulling her hair down, it floats up.
• So, Sunita's hair stands up because there is no force pulling it down like on Earth.

Hence, Option B, "Absence of the pull of earth," is the correct answer.

• Sunita Williams traveled 360 kilometers away from the Earth in the spaceship.
• This is a very far distance from where we live on Earth.

• The shape of the Earth is called a sphere.
• A sphere is round, like a ball.
• However, the Earth is not a perfect sphere; it's slightly flattened at the top and bottom (the North and South Poles).

• Sunita Williams set the record for the longest space flight by a woman in 2007 during her mission aboard the International Space Station (ISS).
• She spent 195 days in space during this mission.

• The shiny objects we see moving steadily in the night sky are called satellites.
• Satellites orbit (move around) the Earth.
• They help with many things, like TV signals, phone calls, and weather reports.
• When you see a light moving steadily in the sky at night, it could be a satellite!

• The biggest challenge for Sunita Williams while being in space was learning to do simple daily chores such as eating, drinking, and sitting in a certain position.
• In space, due to zero gravity, everything floats, making simple tasks much more difficult.
• Astronauts have to adjust to this environment and learn new ways to manage everyday activities.
• While meteorites and loneliness are concerns in space, the daily challenge of adapting to zero gravity affects astronauts the most.

Hence, Option A is the correct answer.

• We see the half-moon during the first and last quarter phases of the moon.
• This happens because only half of the moon is illuminated (lit up) by the Sun during these times.
• The other half is in shadow, which is why we see only half of the moon shining in the sky.

Hence, Option C is the correct answer.

• Neil Armstrong was the first man to walk on the surface of the moon in 1969.
• This historic event took place during the Apollo 11 mission.
• Armstrong famously stated, "That's one small step for man, one giant leap for mankind," as he stepped onto the moon's surface.
• This achievement was a significant milestone in space exploration and human history.

• True! The earth is like a big magnet that pulls things like toys, books, and even people towards it.
• Just like when you drop your toy car, it falls to the ground because the earth is pulling it.
• This pull is called gravity.
• So, everything stays on the ground because the earth is always pulling it down.

• Stars are mainly visible at night because there is no sunlight.
• During the day, the Sun's bright light makes it hard to see the stars.
• At night, the dark sky allows us to see the stars clearly.

Hence, Option B is correct.
