Answer:
Energy Conservation
Explanation:
Energy Conservation involves using less energy service in an effort to reduce the amount of energy being consumed.
Julie reduces the energy she uses on a normal day by turning her lights off when they are not in use. This will save the amount of energy that would be wasted when the lights are turned on when not needed by Julie. Also, when she unplugs all electronic devices at night, energy is conserved. Julie has conserved energy in these simple acts of hers by reducing wastage, and thereby reduced the pressure on the demand for more energy. By so doing, the need for energy service is reduced which in turn would have positive impact on the environment.
Environmental quality is improved as energy conservation reduces the need for energy services.
The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.
