The correct option is (c) 1 and 3 only.
Explanation
A globe is a true model (miniature form) of the Earth. Globes vary significantly in size, material, and utility to serve different educational and practical purposes.
- Statement 1 is Correct: Globes are manufactured in various sizes and types. They range from large, detailed models used in classrooms and libraries to small, portable versions.
- Statement 2 is Incorrect: Small pocket globes are designed for portability. They are typically made of lightweight materials like plastic or are inflatable (like balloons), making them easy to carry. They are not generally made of heavy metal, as weight would defeat the purpose of a "pocket" globe.
- Statement 3 is Correct: Big globes, which provide detailed geographical information, are bulky and occupy significant space. Due to their size and rigid structure, they cannot be carried or transported easily compared to folding or pocket globes.
Key Takeaway:
While globes are accurate three-dimensional representations of the Earth, their utility depends on their construction; pocket globes are designed to be handy and lightweight, whereas large globes are stationary and difficult to transport.
