Which statement best describes the relationship of photosynthesis and energy?
the process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is
stored in the bonds of glucose.
the process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be
used for cell functions.
the process of photosynthesis is energy-conserving because no energy is used throughout the process of forming glucose
and oxygen molecules.
the process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that depletes the cell of
energy stored in the bonds of glucose.

the answer for this question would be d. glaciers

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.

c. heat from the poles back down towards the equator.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
