The revolution changes the Sun-Earth gravitational pull The Earth’s rotation causes annual changes in its surface temperature The tilt of the Earth’s axis and its revolution around the sun produces seasons The Earth’s precession affects the amount of heat reflected from it surface. Which of the following chemical reactions produce the sun’s energy? Helium nuclei are combined by nuclear fusion Oxygen is present to cause combustion of solar fuel molecules Hydrogen nuclei combine through nuclear fusion into helium Helium and oxygen break down through nuclear fission How is energy essential to plants? Solar energy maintains the internal temperature of the plants Solar energy is converted to chemical energy used by the plants Solar energy signals the plants to release leaves in the fall Solar energy regulates the consumption of oxygen by the plant How does the sun’s energy affect food webs on Earth? The ultraviolet radiation of the sun generates ozone for plants to support all life. The wavelengths of visible light stimulate plant cells to produce energy compounds by photosynthesis The microwaves emitted by the sun stimulate animal reproduction in the rainforest How is the balance of heat energy maintained in the oceans? The sun’s energy is equally distributed throughout the oceans The tides transfer heat energy across the oceans The movement of waves transfers heat energy throughout the oceans Heat energy is cycled by currents between the equator and the polar regions When is the subsurface of the water cycle completed? When groundwater emerges in places where the water table interacts with the ground surface When precipitation produces runoff into streams above the surface When water remains in the ground as part of the water table When infiltrates the ground after rain, sleet, or snow accumulate In what type of soil would seepage of groundwater into streams occur the slowest? Fine sand Gravel Fine clay Silt How would several wells in a given area affect the balance of groundwater recharge and discharge?
