NCERT MCQ Solutions for Class 5 EVS Looking Around Chapter 11 Sunita in Space

Astronauts on long-duration missions can spend many months in space. Some have stayed for more than six months, conducting experiments and maintaining the space station.

In the zero-gravity environment of space, water does not flow. Due to surface tension, it forms floating blobs or spheres that astronauts must catch to use.

In the microgravity of space, there is no “down” for things to fall toward. As a result, an astronaut’s hair will float and stand on end.

Due to weightlessness, astronauts must carefully manage their food, which often comes in special packets. They learn to handle floating food and utensils in the spacecraft’s dining area.

From space, the Earth is seen as a whole planet with continents and oceans. The political borders that divide countries on our maps are not physically visible.

Many spacecraft, like the International Space Station, are in Low Earth Orbit (LEO). This is typically several hundred kilometers (e.g., around 360-400 km) above the Earth’s surface.

Earth has a strong gravitational pull. This force attracts all objects with mass towards its center, causing them to fall downward when dropped.

Political borders are human-made concepts drawn on maps to divide land. They are not natural, physical lines on the Earth’s surface and are therefore invisible from space.

Many astronauts were inspired as children by the achievements of space pioneers. Seeing images of early explorers, like Neil Armstrong walking on the moon, sparked their dreams.

Astronauts often set records during their missions. These can include the longest time spent in space on a single flight or the most time spent doing spacewalks.

In a weightless environment, astronauts use various restraints to stay put. These include foot loops, handrails, and straps to secure themselves while working or sleeping.

After retiring, many astronauts use their unique experiences to inspire others. They often engage in public speaking or become teachers to share their passion for science and exploration.

During the day, our sun’s bright light is scattered by the atmosphere, making the sky appear blue. This scattered light is much brighter than faint starlight.

There are many paths to becoming an astronaut. Many start as military pilots, while others come from fields like engineering, medicine, or scientific research like geology or diving.

On Earth, air resistance affects how objects fall. It slows down the wide, light paper much more than the small, dense coin, making the coin fall faster.

A playground slide relies on gravity to pull a person downwards along its slope. In the zero-gravity environment of space, there is no “down,” so you wouldn’t slide.

The Moon doesn’t actually change shape. The phases we see are due to our changing perspective of the Moon’s sunlit half as it orbits the Earth each month.

Since water floats in space, astronauts use a no-rinse body wash and shampoo with a small amount of water on a towel to stay clean.

Astronauts are part of a close-knit professional community. They train together, support each other’s missions, and often honor the memory of colleagues who have been lost.

An astronaut’s journey often shows that success comes from hard work and adapting to new opportunities, even if it means changing from an original plan.
