Mars and General Science Quiz

Vitamins are classified into two main categories: water-soluble (B-complex vitamins, C) and fat-soluble (A, D, E, K). Mineral-rich and oxidizable are not vitamin classifications.

Multi-touch pads and punch cards are user input devices. Flatpanel and video camera are output/display devices, mainframe is a computer type, and projector is an output device.

A stable is the shelter or building where horses are kept. Kennels are for dogs, dens are typically for wild animals like foxes, and burrows (option C, misspelled as 'Borrow') are underground tunnels dug by animals. Stables provide protection from weather and have stalls for individual horses.

Whales are mammals that live in the ocean, breathing air and nursing their young with milk. The question incorrectly states 'only mammal' since dolphins, porpoises, seals, sea lions, walruses, and manatees are also marine mammals. Despite this, whale is still the correct answer among the options.

Ostrich eggs are the largest eggs laid by any living bird species, weighing approximately 1.4 kg and measuring up to 15 cm in diameter. A single ostrich egg contains about 2,000 calories and is equivalent to roughly 24 chicken eggs. Vultures, eagles, and penguins lay smaller eggs by comparison.

Viking 1 and Viking 2 were the first spacecraft to successfully land on Mars and perform their missions, landing in 1976. They conducted biological experiments to search for signs of life. Mariner 9 was an orbiter, not a lander, and Voyager spacecraft were sent to study outer planets, not Mars.

Pure seawater is actually colorless in small quantities. The blue appearance we see in oceans and seas is due to water's molecular properties - it absorbs longer wavelengths of light (red, orange) and scatters shorter blue wavelengths, making large water bodies appear blue.

Mars has two primary geological regions: the Northern Lowlands and the Southern Highlands. The Southern Highlands (also called Terra Meridiani) cover most of the southern hemisphere and are heavily cratered, dating back to Mars's early history. Options B, C, and D are not among Mars's major regions.

Olympus Mons is the highest mountain and largest volcano on Mars, standing about 72,000 feet (13.6 miles) high - nearly three times the height of Mount Everest. Mauna Loa is an Earth volcano, and Valles Marineris is a massive canyon system, not a mountain. 'Romo rivera' appears to be garbled text.

Valles Marineris is a massive canyon system on Mars that spans approximately 2,400 miles (4,000 km) long - about 4-5 times the length of the Grand Canyon. It reaches depths of up to 7 miles and was likely formed by tectonic activity rather than water erosion.

The average surface temperature on Mars is approximately -81°F (-63°C). Mars is much colder than Earth due to its thin atmosphere and greater distance from the Sun. Temperatures can vary from -195°F at the poles to 70°F at the equator during midday.

Mars's atmosphere is composed of about 95% carbon dioxide, 2.7% nitrogen, 1.6% argon, and only trace amounts of oxygen. This composition is quite different from Earth's nitrogen-rich atmosphere and contributes to Mars's inability to retain heat or support liquid water on its surface.
