A student developed a model to use in science class. The model consisted of a game that was designed to explain mechanisms that operate in evolution. The game consisted of placing a large white square and a large black square on the floor. One student then tossed 100 small white circles
and 100 small black circles on each of the two squares on the floor. Two students were then asked to pick up as many circles from each square as
they could in 30 seconds. The students then had to count the number of black circles and white circles that they had picked up from each square.
What was the purpose of the game?
To recognize the importance of a standardized taxonomic system
To analyze how natural selection produces changes in populations
To evaluate the effect of genetic drift on gene frequency in a population
To examine the sudden appearance of a species in the fossi record

the most logical answer would be a

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.
