Which continent contains the South Pole?

• North America
• Antarctica
• South America
• Asia

The South Pole is the southernmost point on the Earth. It is the precise point of the southern intersection of the Earth's axis and the Earth's surface. From the South Pole, all directions are north. Its latitude is 90 degrees south, and all lines of longitude meet there (as well as at the North Pole, on the opposite end of the Earth). The South Pole is located in Antarctica, one of the Earth's seven continents. Although land at the South Pole is only about a hundred meters above sea level, the ice sheet above it is roughly 2,700 meters (9,000 feet) thick. This elevation makes the South Pole much colder than the North Pole, which sits in the middle of the Arctic Ocean. In fact, the warmest temperature ever recorded at the South Pole was a freezing -12.3 degrees Celsius (9.9 degrees Fahrenheit).

Which of these words refers to the hottest days of summer?

• Mouse days
• Dog days
• Elephant days
• Lion days

The dog days or dog days of summer are the hot, sultry days of summer. They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck. They are now taken to be the hottest, most uncomfortable part of summer in the Northern Hemisphere. Sirius is by far the brightest proper star in the night sky, which caused ancient astronomers to take note of it around the world. In Greece, it became known as the precursor of the unpleasantly hot phase of the summer. Greek poets even recorded the belief that the return of the bright star was responsible for bringing heat and fever with it.

Kindling point is the lowest temperature where a substance will do what?

• Boil
• Float
• Melt
• Catch Fire

The autoignition temperature or kindling point of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion. The temperature at which a chemical ignites decreases as the pressure increases. The ignition temperature is the lowest temperature at which substances catch fire. Substances that spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric.

As of 2023, where was the coldest temperature recorded on Earth?

• Africa
• Antarctica
• Asia
• Australia

The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements. On 10 August 2010, satellite observations showed a surface temperature of −93.2 °C (−135.8 °F; 180.0 K) at 81.8°S 59.3°E, along a ridge between Dome Argus and Dome Fuji, at 3,900 m (12,800 ft) elevation. The result was reported at the 46th annual meeting of the American Geophysical Union in San Francisco in December 2013; it is a provisional figure and may be subject to revision. The value is not listed as the record lowest temperature as it was measured by remote sensing from satellite and not by ground-based thermometers, unlike the 1983 record.

According to Ray Bradbury, at what temperature does book paper burn?

• Fahrenheit 312
• Fahrenheit 451
• Fahrenheit 110
• Fahrenheit 157

Author Ray Bradbury named his most famous book, Fahrenheit 451, after “the temperature at which book paper catches fire, and burns.” Bradbury’s title refers to the auto-ignition point of paper—the temperature at which it will catch fire without being exposed to an external flame. In truth, there’s no authoritative value for this. Bradbury asserted that “book paper” burns at 451 degrees, and it’s true that different kinds of paper have different auto-ignition temperatures. Experiments have found, for example, that the auto-ignition temperature for newspapers is about four degrees lower than that of the filter paper used in chemistry laboratories.

The radiator in a car helps with which of these?

• Cooling
• Accelerating
• Storing fuel
• Braking

A radiator helps to eliminate excess heat from the engine. It is part of the engine's cooling system, which also includes a liquid coolant, hoses to circulate the coolant, a fan, and a thermostat that monitors the coolant temperature. The coolant travels through the hoses from the radiator, through the engine to absorb the excess engine heat, and back to the radiator. Once it returns to the radiator, thin metal fins release the heat from the coolant to the outside air as the hot liquid passes through it. Cool air flows into the radiator through the car's grille to aid in this process, and when the vehicle isn't moving, such as when you're idling in traffic, the system's fan will blow air to help reduce the heated coolant's temperature and blow the hot air out of the car.

What is the science of materials at low temperatures called?

• Fluid Mechanics
• Thermodynamics
• Genetics
• Cryogenics

In physics, cryogenics is the production and behavior of materials at very low temperatures. The 13th IIR International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (or –153 °C) to distinguish these terms from conventional refrigeration. This is a logical dividing line since the normal boiling points of the so-called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below 120K while the Freon refrigerants, hydrocarbons, and other common refrigerants have boiling points above 120K. The U.S. National Institute of Standards and Technology considers the field of cryogenics as that involving temperatures below -153 Celsius (120K; -243.4 Fahrenheit).

According to NASA, what is the temperature at the Sun's surface?

• 300 degrees Fahrenheit
• 10,000 degrees Fahrenheit
• 2,000 degrees Fahrenheit
• 180 degrees Fahrenheit

The sun is a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy. The sun's surface temperature is 10,000 degrees Fahrenheit.

What does drinking alcohol in cold temperature actually achieve?

• Improve circulation
• Decrease body temperature
• Make you warmer
• Keep you awake

Drinking alcohol can decrease body temperature. According to studies over the years, while alcohol may seem like the perfect cold-weather beverage because it creates a sensation of warmth, it actually decreases core body temperature regardless of the temperature outside and increases the risk of hypothermia. The normal process that makes us feel cold occurs when blood flows away from the skin and into the organs, which increases core body temperature. Alcohol reverses this process, increasing the flow of blood to the skin and setting off a sharp drop in body temperature.

What is the hottest temperature ever registered in the Mojave Desert?

• 100 degrees F
• 250 degrees F
• 119 degrees F
• 134 degrees F

Death Valley is famous as the hottest place on earth and the driest place in North America. The world record highest air temperature of 134 degrees F (57°C) was recorded at Furnace Creek on July 10, 1913. Summer temperatures often top 120°F (49°C) in the shade with overnight lows dipping into the 90s°F (mid-30s°C.) The average rainfall is less than 2 inches (5 cm), a fraction of what most deserts receive. Occasional thunderstorms, especially in late summer, can cause flash floods.
