One proposed method of mitigating climate change is the planting of large numbers of trees. How would this reduce the problem of global warming? Trees reflect additional sunlight back into space before it strikes the ground, reducing the global temperature. Trees absorb carbon dioxide, reducing the amount of carbon dioxide in the atmosphere and thereby reducing the greenhouse effect. Trees prevent soil erosion, and soil erosion contributes to the greenhouse effect. Trees release water vapor into the atmosphere, increasing the cloud cover and reducing the global temperature.

- Q19 Does our ability to survive on Earth’s surface depend on the greenhouse effect? Explain.You are camping on the North Rim of the Grand Canyon at an elevation of 8200 feet. When it is 75°F at your camp, it is 104°F along the Colorado River at the canyon's bottom at an elevation of 2400 feet. What is the average rate of change in temperature with rising elevation?Book: Sustainable Energy, Si Edition, 2nd Edition by Richard A. Dunlop Chapter 15 - Problem 6. Assume that geothermal heat transfer (at least near the surface of the earth) is by conduction through the crust rocks. For an average geothermal heat flow of 0.087 W/m2 and typical thermal gradient of 1008C/km, calculate the thermal conductivity of the rock. Compare with the known thermal conductivities of similar materials given in Chapter 8.

At the end of summer, you can assume the average surface water temperature is about 20 °C and the bottom of the lake is about 10 °C. Explain in detail what happens as the cold air of winter arrives. Be sure to discuss in detail how various heat transfer mechanisms are working.Why do fishermen sail out to the sea in the night? What process helps them to sail easily to the sea in the night and come back to the shore in the morning? think about processes like conduction, convection and radiation
- The rate at which a resting person converts food energy is called one’s basal metabolic rate (BMR). Assume that the resulting internal energy leaves a person’s body by radiation and convection of dry air. When you jog, most of the food energy you burn above your BMR becomes internalenergy that would raise your body temperature if it were not eliminated. Assume that evaporation of perspiration is the mechanism for eliminating this energy. Suppose a person is jogging for “maximum fat burning,” converting food energy at the rate 400 kcal/h above his BMR, and putting out energy by work at the rate 60.0 W. Assume that the heat of evaporation of water at body temperature is equal to its heat of vaporization at 100°C. (a) Determine the hourly rate at which water must evaporate from his skin. (b) When you metabolize fat, the hydrogen atoms in the fat molecule are transferred to oxygen to form water. Assume that metabolism of 1.00 g of fat generates 9.00 kcal of energy and produces 1.00 g of…4. Wind chill describes the additional cooling that occurs when skin is exposed to wind. The equation is W(v)=-0.17v³+18.4v²-584v-239 for 0 ≤ v ≤ 45, where v is the wind speed in metres per second. The units for W are megajoules per square metres per hour. Determine the speed of the wind that gives a minimum wind-chill factor.2. Gross primary productivity in an equatorial grassland is 8,000 cal/m'/yr. This particular region has such a high efficiency that the grasses use only 75% of the energy in cellular respiration. Calculate the energy (calories) that is available to secondary consumers from 1 m of grassland over a year's period. 2. 8000 x75% =6000 callm/yr 0 callm²lyr
- The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?5) In the Swiss Alps, the air pressure is relatively low due to the high elevation.
