It would be slightly worse than taking it off in space. The atmosphere on the surface of Mars is nearly a vacuum, so the astronaut would do well to notice the boiling saliva and tears and reseal the helmet immediately. Failing that, he or she would pass out in a few seconds, which is perhaps just as well. In space, you can only cool off by evaporation or by radiating infrared into space. On Mars, the tenuous air is just barely thick enough to conduct heat, and it’s generally colder than northern Siberia in the January. So…yeah. Don’t do that.
A landform is simply any natural geographic feature that can be found on the earth’s surface, such as valleys, hills, mountains and plateaux. Landforms are all not the same. Some may be very high above sea level and other parts may be deep below sea level. Some of them are made of very hard material and other parts may be made of very soft material. Some landforms are covered by vegetation whiles some are void of any plant at all. Some are very large and others are small. Most important of all, landforms are constantly changing because the factors that form them are in action everyday! - landforms
A relief map is a 2 or 3 dimensional map that shows varying elevations. On 2 dimensional versions shading is done using different colors are used to show varying degrees of elevation for things like mountain ranges. The 3 dimensional maps are the most impressive. Combined with the color a variety of different materials –plastic, rubber etc. –are used to display different features like valleys, mountains, rivers. The result is a map on which you can actually see and touch the top of Everest and the floor of Death Valley. - relief map
D = m/V
m = 75g
V = 4 x 4 x 4 = 64 cm^3
d = 75/64 = 1 11/64 g/cm^3
<span>The most correct choice is (d). Muscle cells, after they have performed heavy work, start to break down six-carbon sugars into energy and lactic acid. In areas where oxygen is present, fermentation will likely not occur, and cellular respiration will take place in its stead.</span>
