11. Which factor best explains the reason that average summer
temperatures are higher than winter temperatures in North America?
4 points
The Earth is closer to the sun during the summer months.
Cyclical activity on the Sun causes more radiant energy to be produced.
North America is tilted toward the Sun during the summer months.
Ocean water temperatures near the Equator influence North America during the
summer.

North America is tilted towards the sun in the summer months

you are the source of the heat energy. you can minimize the heat energy by selecting the appropriate clothes to wear.

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.
