The smallest planet in the solar system, Mercury bears a strong resemblance to Earth's moon. Like the other three terrestrial planet, Mercury contains a core surrounded by a mantle and a crust. But Mercury's core makes up a larger portion of the planet than others in the solar system, hi...
While mercury emissions are notoriously difficult to pin down, most sources agree that human activities put more mercury into the atmosphere than natural ones, perhaps 2,900 tons per year [source: UDEQ]. That mercury can come from mining and processing for use in products (like those thermomete...
Scientists who study the Sun usually divide it up into three main regions: the Sun's interior, the solar atmosphere, and the visible "surface" of the Sun which lies between the interior and the atmosphere. There are three main parts to the Sun's interior: the core, the radiative zone, ...
Atmosphere Abbr. atm Physics A unit of pressure equal to the air pressure at sea level. It equals the amount of pressure that will support a column of mercury 760 millimeters high at 0 degrees Celsius under standard gravity, or 14.7 pounds per square inch (1.01325 × 105 pascals). Air Exp...
Also, the atmosphere refracts the sun's light and it continues to travel to "nighttime" Earth for a short period, even after the sun has dipped below the horizon. "On the equinox and for several days before and after the equinox, the length of day will range from about 12 hours and ...
No wonder, then, that water makes up nearly 60 percent of our bodies or that we can't go for more than a few days without it. Besides being essential for our bodies to function, water also promotes life in numerous other ways. Without it, we couldn't grow crops, keep livestock or ...
What makes up a moon crater? How does the moon shine? How much light does the moon reflect? What holds the moon in orbit? When was it discovered that the moon reflects light? What is the moon made of? What gives a star its color?
Answer to: What would happen to the temperature of an atmosphere (at a pressure of 10 kPa) of 252 K if the pressure was increased to 101.3 kPa? By...
research published inNature. However, most electronic waste still ends up in landfills or gets incinerated, wasting useful resources and releasing toxic chemicals and other pollutants — such as lead, mercury, and cadmium — into the soil, groundwater, and atmosphere to thedetriment of the ...
of bodies and reproductive cells and stable storage of biological samples also makes use of liquid nitrogen. nitrogen makes up 78 per cent of the earth’s atmosphere and is a part of all living tissue. nitrogen is a crucial ingredient of life since it is a constituent of dna and as such...
