PLEASE HELP ASAP! WIll GIVE The latitude of a particular ecosystem determines the climate zone of the ecosystem. What type of seasonal variation occurs in ecosystems in temperate zones, which are latitudes between 23.5° and 66.5°?

Temperate zones experience warm, pleasant weather all year long because the amount of sun they receive is relatively constant all year.
Temperate zones experience extremely hot summers and brief, mild winters because this zone receives direct sun all year.
Temperate zones experience hot summers and cold winters because the sun is lower in the sky in the winter compared to summer.
Temperate zones experience short, mild summers and extremely cold winters because this zone receives less direct sun all year.

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.
