Is natural gas heavier or lighter than air?
Lighter-than-air natural gas (methane) should not be confused with liquefied petroleum gas. This gas is more commonly called L.P., bottle gas, propane, butane and various other trade names. Liquefied petroleum gases are all heavier than air and will collect in low places when not confined.

Why does the moon control the tides?
The tides are due to the gravitational pull of the Moon and the Sun on the Earth. Because the gravitational force decreases as the distance squared, the part of the Earth that is closer to the Moon or the Sun is pulled a little extra and a bulge is created.

How long does it take to recover from giving blood?
Your body will replace the blood volume (plasma) within 48 hours. It will take four to eight weeks for your body to completely replace the red blood cells you donated. The average adult has eight to 12 pints of blood. You will not notice any physical changes related to the pint you donated.

How many inches is a newborn baby's head?
The bones in your baby's skull are still growing together, and the skull is growing faster during the first four months than at any other time in her life. The average newborn's head circumference measures about 13 3⁄4 inches (35 cm), growing to about 15 inches (38 cm) by one month.

How high are the clouds?
Low-level clouds lie below 6,500 feet (2,000 meters). Meteorologists refer to them as stratus clouds. They're often dense, dark, and rainy (or snowy) though they can also be cottony white clumps interspersed with blue sky. The most dramatic types of clouds are cumulus and cumulonimbus, or thunderheads.

How many weeks is a normal human pregnancy?
Childbirth usually occurs about 38 weeks after conception; in women who have a menstrual cycle length of four weeks, this is approximately 40 weeks from the start of the last normal menstrual period (LNMP). Human pregnancy is the most studied of all mammalian pregnancies.

How are diamonds formed?
Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).

Why are there 60 seconds in a minute?
THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.

Is light an energy?
Electromagnetic energy is the same as radiation or light energy. This type of kinetic energy can take the form of visible light waves, like the light from a candle or a light bulb, or invisible waves, like radio waves, microwaves, x-rays and gamma rays.

How many different kinds of animals are there in the world?
According to World Book Encyclopedia, "So far scientists have named and classified more than 1 1/2 million animals. Over half of these are types of insects and other species are discovered each year. Scientists believe there may be from 2 million to as many as 50 million kinds of animals alive today."

What is the dew point?
Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure.

What percent of the population is ambidextrous?
About 90 percent of people are right-handed, says Corballis. The remaining 10 percent are either left-handed or some degree of ambidextrous, though people with "true" ambidexterity—i.e., no dominant hand at all—only make up about 1 percent of the population.

What continent has the most deserts?
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 inches) along the coast and far less inland.

What diseases can you get from lack of vitamin C?
Scurvy is a disease caused by a diet that lacks vitamin C (ascorbic acid). Patients develop anemia, debility, exhaustion, edema (swelling) in some parts of the body, and sometimes ulceration of the gums and loss of teeth. The name scurvy comes from the Latin scorbutus.

What organs can regenerate themselves?
The liver is the only human internal organ capable of natural regeneration of lost tissue; as little as 25% of a liver can regenerate into a whole liver. Regeneration is very rapid. The liver will return to a normal size in one to two weeks following the removal of greater than 50% of the liver by mass.
