Geography and Astronomy General Knowledge Quiz

N'Djamena is the capital and largest city of Chad, located at the confluence of the Chari and Logone rivers. It was founded in 1900 as Fort-Lamy and renamed N'Djamena after independence in 1973.

Bogota is the capital and largest city of Colombia. Located in the Andes mountains, it's the country's political and economic center, known for its colonial architecture and cultural significance in Latin America.

Ouagadougou (spelled 'Ougadougou' in the question) is the capital and largest city of Burkina Faso. It's the country's administrative and economic center, known for its markets and as a hub for West African music and culture.

Quito is the capital of Ecuador and the second-highest capital city in the world at 2,850 meters above sea level. It's known for its well-preserved colonial center and proximity to the equator, from which Ecuador takes its name.

San Salvador is the capital and largest city of El Salvador. It's the political, cultural, and economic center of the country, founded in 1525, and is located in a valley surrounded by volcanoes.

Praia is the capital and largest city of Cape Verde, located on the island of Santiago. It became the capital in 1770 when the seat of government was transferred from Ribeira Grande (now Cidade Velha). The other options (Minilia, Zilina, Polongo) are not real cities in Cape Verde.

Havana is the capital and largest city of Cuba, founded in 1519 by Spanish conquistadors. It has served as Cuba's capital since the colonial period and is located on the island's northwest coast along the Straits of Florida. The other options are fictitious names not associated with any Cuban cities.

The Sun's composition is approximately 71% hydrogen, 26.5% helium, and about 2.5% heavier elements (oxygen, carbon, nitrogen, etc.). These ratios are determined by spectroscopic analysis of the Sun's photosphere. Option D matches these accepted values.

Venus is called the 'morning star' when it appears in the east before sunrise, and the 'evening star' when it appears in the west after sunset. This is because Venus's orbit is closer to the Sun than Earth's, so it's always visible relatively near the Sun in our sky. It's not actually a star, but the brightest planet in our sky.

Uranus takes approximately 84 Earth years to complete one orbit around the Sun. This long orbital period is due to Uranus's great distance from the Sun - about 2.9 billion km (19.2 AU) at its average distance.

Jupiter takes approximately 11.9 Earth years (about 4,333 days) to complete one revolution around the Sun. This matches option D. Jupiter's long orbital period is due to its large average distance from the Sun - about 5.2 AU or 778 million km.

Mars takes approximately 687 Earth days to complete one orbit around the Sun, equivalent to about 1.88 Earth years. This orbital period is fundamental to astronomy and explains Mars' seasonal cycle (nearly twice as long as Earth's) and is critical for planning space missions to the red planet.

Earth's sidereal rotation period is 23h 56m 4.09 seconds - the time to rotate 360° relative to fixed stars. This differs from the solar day (24h) because Earth orbits the Sun, requiring slightly more rotation to face the Sun again. Option C incorrectly states 57 minutes instead of 56.

The Durand Line is the international border between Pakistan and Afghanistan, established in 1893 through an agreement between Sir Mortimer Durand (British India) and Abdur Rahman Khan (Afghan Amir). It remains a significant geopolitical boundary in the region. Note that option A contains a common spelling error ('Durond' instead of 'Durand').

The English Channel, separating southern England from northern France, is approximately 594 kilometers (369 miles) long at its widest point. It has been a historically significant maritime crossing and route for trade, migration, and invasion throughout European history.

The Suez Canal, connecting the Mediterranean Sea to the Red Sea, is approximately 162.5 kilometers (101 miles) long. This artificial sea-level canal, completed in 1869, dramatically shortened shipping routes between Europe and Asia without the need to circumnavigate Africa.
