- Which biogeochemical cycle does not have a gaseous component but cycles from the land to sediments in the ocean and back to the land? (a) carbon cycle (b) nitrogen cycle (c) phosphorus cycle (d) hydrologic cycle (e) neither a nor c has a gaseous componentINTERTRET DATA Scientists have compiled databases of large forest wildfires in the western United States and compared them to climate and land-surface data. Examine the graph showing wildfire frequency compared to average springsummer temperature. Do you see a correlation? If so, describe it. Based on these data, do you think that climate warming is causing more wildfires? Explain your answer.Consider yourself as an owner of a factory using fossil fuel as energy source. Now as an environmental expert, you want to make some decisions or rules in your company to reduce the pollution and also to reduce the global warming. What are the steps that you will take? Explain it in detail.
- Defend the statement that the more and longer we use fossil fuels as the dominant fuel in the world, the greater the adverse impacts of that use will be in terms of air and water pollution and the greater the potential disruption for society as increasing worldwide population competes for limited fossil fuels.Scientists at the Global Footprint Network calculate the energycomponent of our ecological footprint by estimating the amountof ecologically productive land and sea required to absorb thecarbon released from fossil fuel combustion. This translates into4.9 ha of the average American’s 7.2-ha ecological footprint.Another way to think about our footprint, however, is to estimatehow much land would be needed to grow biomass with anenergy content equal to that of the fossil fuel we burn.Assume that you are an average American who burns about6.3 metric tons of oil-equivalent in fossil fuels each year andthat average terrestrial net primary productivity (p. 32) can beexpressedas 0.0037 metric tons/ha/year. Calculate how manyhectares of land it would take to supply our fuel use by presentdayphotosynthetic production. Compare the energy component of your ecological footprintcalculated in this way with the 4.9 ha calculated usingthe method of the Global Footprint Network. Explainwhy results from…Which of the following is a renewable energy resource? I. Solar II. Wind III. Geothermal IV. Natural Gas A. I and II only B. III and IV only C. I, II and III D. II, III and IV
- A family travels from New York City to Costa Rica three times a year for a vacation. The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2. Calculate the mass of carbon, in kilograms, that is emitted by the family as a result of their round-trip flights to Costa Rica each year. 3. Calculate the number of acres of forest that must be…Energy sources: need advatages and disadvantages for each Non-renewable — Fossil fuels Nuclear power Renawables — Hydroelectric power Solar power wind power Geothermal Tidal power Wood power Bioenergy hydrogen powerestimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 Kg
