Answer the following questions

Question 1. What is the significance of Sunita Williams’ experience in space in understanding the shape of the Earth?

when viewed from a distance.

Question 2. How did Sunita Williams describe the Earth when she saw it from space?

Answer

Sunita Williams described the Earth as beautiful and amazing, with a clear view of its curved shape.

Question 3. Why do objects appear to float in a spaceship in space?

Answer

Objects appear to float in a spaceship in space because there is no gravitational force pulling them towards the floor or any other surface.

Question 4. What does Sunita Williams mean when she asks, “Where are the lines, really?” in relation to the Earth?

Answer

Sunita Williams is questioning the concept of division into countries and borders, wondering if those lines truly exist or if they are just creations of human imagination.

Question 5. Explain the phenomenon of stars twinkling in the night sky.

Answer

Stars twinkle in the night sky due to the effect of Earth’s atmosphere, which causes the starlight to scatter and create a twinkling effect.

Question 6. Why is it challenging for scientists and young children to understand the shape of the Earth?

Answer

Understanding the shape of the Earth is challenging because it requires observing the Earth from a distance or space, which is not easily accessible. Additionally, young children may truggle with conceptualizing a three-dimensional shape.

Question 7. How did Sunita Williams’ hair behave in space, and why?

Answer

Sunita Williams’ hair kept standing in space because there was no gravity to pull it down. Without the force of gravity, hair and other objects in space tend to float or remain in a suspended position.

Question 8. What is the difference between a star, a shooting star, and a satellite?

Answer

A star is a luminous celestial object that produces its own light. A shooting star, also known as a meteor, is a small particle entering Earth’s atmosphere and burning up, creating a brief streak of light. A satellite is an object that orbits around a planet or star and can be human-made or natural, such as the Moon.

Question 9. How does the Earth’s gravity affect the behaviour of objects on its surface?

Answer

The Earth’s gravity pulls objects towards its center, causing them to fall towards the ground when released or dropped. Gravity also keeps the oceans in place and influences the flow of water downhill.

Question 10. What are some of the challenges Sunita Williams faced while living in space, and how did she adapt to them?

Answer

Sunita Williams faced challenges such as floating in the spaceship instead of being able to sit or walk normally, having to catch floating water blobs for washing, and needing to strap herself to stay in one place. She adapted by using straps and adhesives to secure objects, catching floating food packets, and adjusting to a different way of performing daily tasks.
