Take a look at the statement below:

fish meal is better than artificial fertilizers.

how could this statement be revised to make it a hypothesis?
a.) fish meal is safer than artificial fertilizers, but it does not make plants grow. b.) fish meal is a better fertilizer than artificial fertilizer because fish meal is natural.
c.) plants that are fertilized with fish meal will grow taller than plants that receive artificial fertilizer.
d.) plants that receive artificial fertilizer will be better than plants that receive fish meal.

The correct answer is option C, that is, plants that are fertilized with fish meal will grow taller than plants that receive artificial fertilizer.

Explanation:

The given hypothesis is that fish meal is better in comparison to artificial fertilizer. The revised statement to this hypothesis could illustrate the influence of fish meal that influences the plant in a better manner in comparison to the artificial fertilizers. Thus, the statement that is when the plants are fed with a fish meal they grow taller in comparison to the plants, which are fed with artificial fertilizer is the correct one.

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.
