13.) A skier on a ski lift is making her way to the top of the ski mountain. As the skier moves higher a. The kinetic energy being used to move her up the hill is stored in her by her position b. The potential energy in her is being stored by kinetic energy c. The mechanical energy is being converted into nuclear energy d. Both potential energy and kinetic energy are being stored in the skier 14.) What type of energy is the energy of moving things? a. Mechanical b. Electromagneticc. Sound d. Thermal 15.) What type of energy is the energy released when an atom is split or fused? a. Nuclear b. Electromagnetic c. Sound d. Electricity 16.) What type of energy is the energy that travels through matter in vibrations? a. Electricity b. Electromagnetic c. Sound d. Thermal 17.) What type of energy is the movement of electrons? a. Mechanical b. Electromagnetic c. Sound d. Thermal 18.) What is the source of all energy on earth? a. Plants b. animals c. Fossil fuels d. the sun 19.) Which type of energy does the match that is burning represent? a. Thermal b. Nuclear c. Chemical d. Mechanical

the correct answer is:

a population changes in response to a change in the environment.

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.

i dont know it at allnow im just getting points at this pint
