Explanation:
Using a maps scale most of the time involves some math. Usually you'd take a distance on the map (in inches) and multiply it to whatever that maps scale is, for example 1:500. A maps scale is used to show larger distances on a map in a ratio form to show the real ground distance. Showing 10 miles on a single piece of paper would be rather difficult if there weren't a scale
Answer:
Explanation: The lab allowed me to model and observe stream and river processes. Using a virtual model, I compared low and high velocity streams or rivers, low and high gradient streams or rivers, and low and high volume streams or rivers. I found that higher velocity streams or rivers can cause more erosion, as do higher gradient and higher volume streams or rivers. Not only did these factors move more small sediment, they also moved larger pieces of sediment.
Greenhouse emissions of tar sand, per barrel, are more than conventional crude oil. This is because, it takes more energy to extract the bitumen from the tar sand and more so, to convert the bitumen to usable oil taking up even more energy. This energy is usually derived from burning natural gas. Emissions by tar sand are approximately 100 kg CO2 per barrel while conventional oil is approximately 30 kg CO2 per barrel.
