They were built out of sod, cut from the ground because wood was too expensive and hard to carry out in the less wooded areas of the prairies
Answer: Carbon
Explanation:Carbon is the element released by volcanic outgassing,animal respiration and flatulence,burning of fossil fuels and the metamorphism of limestone.
Volcanic outgassing is the release of carbon into the atmosphere mainly in the form of carbon monoxide.
Animal respiration and flatulence are process taking place in animals which leads to the release of carbon dioxide.
Burning of fossil fuels is the use of heat to breakdown fossil fuels such as petroleum leading to the release of Carbon.
Limestone metamorphism is the breakdown of limestone which leads to the release of Carbon to the atmosphere.
Answer: contour lines.
Topographic maps are easily recognized by their contour lines.
Answer:
B. Heat absorption increases as the albedo decreases
Explanation:
The ice has very high albedo. The reason for this is that it has white coloration, and the light coloration are highly reflective of the sunlight. As the ice melts though, the water surface increases, and the water, unlike the ice, has the capability of absorbing much more heat. With much more water, there will be much more absorption of heat, and since the water has low albedo on only 10, the albedo will decrease on a global level.
