The diagram is a simplified model of Earth systems and their interactions. The model is used to analyze the causes and effects of global changes to Earth systems, such as changes to Earth's climate. The diagram shows the atmosphere, biosphere, hydrosphere, and geosphere arranged in a ring. In the center is a circle labeled Measurable Changes in the Earth System. The outer ring is labeled Causes of Global Change.

Which statement BEST explains why the model is useful for analyzing global changes to Earth systems?

A. The causes and effects of global changes involve one Earth system only.
B. The causes of global changes involve two Earth systems, and the effects involve the remaining two Earth systems.
C. Earth systems interact with one another, and the causes and effects of global changes involve all of the systems.
D. The causes and effects of global changes act separately on each Earth system, and the systems do not interact with one another.

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.

im not intirely sure but i think the anwser is d relative humidity
