THE RED PLANET
Do you know there are many planets in our solar system and one of them is referred as 'the red planet'? This fourth planet from the sun, which is reddish in colour, is Mars. Mars gets its reddish colour from the high amount of iron oxide on its surface.
Mars is also home to Olympus Mons, the highest discovered mountain in the solar system. With its peak at 88,600 feet, Olympus Mons is about three times as high as Mount Everest, which is 29,029 feet, the highest peak on Earth. Mars' Valles Marineris is the solar system's largest canyon, measuring more than seven miles deep.
Of all the planets, temperatures on Mars are most similar to those on Earth. Unlike Earth, however, the thin atmosphere gives rise to fearsome dust storms that may envelop the entire planet and cause overall temperatures to rise. Mars has an extremely thin atmosphere.
95% of it is carbon dioxide, 3% is nitrogen, 1.6% is argon, and the remainder consists of traces of oxygen and water. Mars has two moons, Phobos and Deimos. Interestingly, Phobos orbits Mars at a distance of only about 5,500 miles from its center, the closest any moon orbits its parent planet. Because Phobos has a particularly low orbit, scientists believe it will eventually crash into Mars or break up into pieces, possibly forming rings around the planet like Saturn.
There has long been speculation concerning the possibility of life and of liquid water on Mars. Some evidence on the planet's surface suggests the presence of liquid water at some point in history, but scientists think this water would be too salty or acidic to support life. There is compelling evidence, however, that Mars was once much more habitable to life than it is today.
Many spacecraft have attempted to visit Mars, the most notable of which was NASA's Mariner 4, the first to visit in a fly-by in 1965. In 1976, Viking 1 and 2 became the first spacecrafts to conduct successful and sustained landings on Mars. They provided the first colour photographs of the "red planet". In May of 2008, the NASA Phoenix lander touched down on the north polar region of Mars to study surface features.
Scientists believe ______will eventually crash into Mars.
Dnone of these
Read the passage and answer the questions that follow.
Flying fish can be seen jumping out of warm ocean waters worldwide. Their streamlined torpedo shape helps them gather enough underwater speed to break the surface, and their large, wing-like pectoral fins get them airborne.
Flying fish are thought to have evolved this remarkable gliding ability to escape predators, of which they have many. Their hunters include mackerel, tuna, sword fish, marlin, and other larger fish. For their nutrition, flying fish feed on a variety of food, including plankton, bacteria and other tiny marine creatures. The average lifespan of flying fish is around five years in the wild. In size they can grow up to 18 inches.
There are about 40 known species of flying fish. Beyond their useful pectoral fins, all have unevenly forked tails, with the lower lobe longer than the upper lobe. Many species have enlarged pelvic fins as well and are known as four-winged flying fish.
The process of taking flight, or gliding, begins by gaining great velocity underwater, about 37 miles (60 kilometers) per hour. Angling upward, the four-winged flying fish breaks the surface and begins to taxi by rapidly beating its tail while it is still beneath the surface. It then takes to the air, sometimes reaching heights of over 4 feet (1.2 metres) and gliding long distances, up to 655 feet (200 metres). Once it nears the surface again, it can flap its tail and taxi without fully returning to the water. Capable of continuing its flight in such a manner, flying fish have been recorded stretching out their flights with consecutive glides spanning distances up to 1,312 feet (400 metres). Flying fish can soar high enough that sailors often find them on the decks of their ships.
Flying fish swim in large schools (groups) and are attracted to light, like a number of sea creatures, and fishermen take advantage of this with ample results. Canoes, filled with enough water to sustain fish, but not enough to allow them to propel themselves out, are affixed with a luring light at night to capture flying fish by the dozens. There is currently no protection status on these animals.
Sailors sometimes find flying fish on their ________.
