Earths energy sources include renewable and non renewableresources. name at least three sources of energy that could be used in your house. then describe the ideal energy source for generatinng most of you homes electricity, and explain why you chose thst source.

One source of energy is Natural Gas and it generates my stove, clothes dryer, etc. Another one is biomass energy, it can fuel a furnace/fireplace. Geothermal energy is also one, it helps you to go below or above that temperature that is the house is either cooled or heated.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
