A population is a group of individuals of the same species that live in the same area. The size of a population is determined by many factors. In the Rabbit Population by Season Gizmo, you will see how different factors influence how a rabbit population grows and changes. Select the BAR CHART tab. What is the size of the initial rabbit population?

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.

looks like the answer is     c     to me!

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
