Brainliest ! hurry its how is cold front formation different from stationary front formation? a) stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass. b) cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses. c) cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold air mass moves over a warm air mass. d) stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when a warm air mass moves over a cold air mass

A. Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass.

A just took the test trust me

Explanation:

the answer to your question is tooth decay.

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.
