Asia is the correct answer because it is the largest continent in the world in terms of both land area and population. It covers approximately 30% of the Earth's total land area and is home to over 4.5 billion people, which is more than half of the world's population. Asia is also known for its diverse geography, including the Himalayas, the Gobi Desert, and the fertile river valleys of the Indus and Yangtze.

The Sahara desert is located in Africa. It is the largest hot desert in the world, covering an area of approximately 9.2 million square kilometers. The desert spans across several countries in North Africa, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, and Tunisia. The extreme aridity and high temperatures make it one of the most challenging environments on Earth.

The Nile is considered the longest river in the world because it stretches approximately 4,135 miles from its source in Burundi to its mouth in Egypt, where it drains into the Mediterranean Sea. It passes through eleven countries in northeastern Africa, including Tanzania, Uganda, South Sudan, Sudan, and Ethiopia. The Nile has played a crucial role in the development of ancient Egyptian civilization, providing fertile land for agriculture and transportation routes. It continues to be a vital water source for millions of people, supporting agriculture, industry, and various ecosystems along its course.

Mercury is the correct answer because it is the smallest planet in the Solar System. It has a diameter of about 4,879 kilometers, making it slightly smaller than Mars and significantly smaller than Venus and Saturn. Mercury's small size is due to its rocky composition and its close proximity to the Sun, which has caused it to lose a significant amount of its original atmosphere and volatile substances.

Greenland is the correct answer because it is the largest island in the world. It is located in the North Atlantic Ocean and is an autonomous territory of Denmark. With an area of approximately 2,166,086 square kilometers, Greenland is larger than any other island on Earth. It is known for its vast ice sheet and stunning natural landscapes.

Located in North America, between the United States and Canada, it is one of the five Great Lakes. Its size and volume make it the largest by surface area and the third largest by volume of all lakes globally. It is known for its pristine waters, diverse wildlife, and stunning natural beauty.

Lithium is the lightest metal in the world. It has a low atomic number and a low density, making it extremely lightweight. It is commonly used in batteries due to its high electrochemical potential and low density. Lithium is also known for its high reactivity and is found in various minerals and salts.

A convex mirror is a diverging mirror because its reflective surface bulges towards the light source. This causes the light rays to spread out and diverge, resulting in a wider field of view.

Seychelles is Africa's smallest country. It is an archipelago located in the Indian Ocean off the eastern coast of Africa. With a total land area of just 459 square kilometers, Seychelles is known for its stunning beaches, coral reefs, and diverse marine life.
