Document Summary
Maritime provinces are the last 3 named above. Uneven distribution of natural resources across the realm. Arid southwest and great plains rely on other areas for water. Natural resources are factors of production which own their production totally or dominantly to natural processes, maybe geological, biological, or chemical. Natural processes occur automatously in the environment. Great lakes contain 20% of worlds freshwater surface. Abundant mineral reserves are in three zones. Fossil fuels, oil, natural gas, coal energy sources. Mineral- natural occurring substance with a specific chemical composition. Not enough to satisfy demand, so imports are necessary. Alternative energy sources, especially nuclear power are not fully developed. Earth receives radiation from sun: plane of the ellipse, on january 2 91. 5 million miles away from the sun. average distance, on july 6 94. 5 million miles. Fusion reactions: gravity force, pressure, heat, fusion, energy release, hydrogen nuclei fuse create helium- release energy 21 million fahrenheit core.
