Imagine that you live in the midlatitudes—say, virginia—and a cyclone passes by. what is the correct sequence of events?

two successive warm fronts
first a cold front and then a warm front
first a warm front then a cold front
two successive cold fronts
first a warm front, then the eye, then a storm surge

First a warm front then a cold front.

Explanation:

Cyclone may be defined as the amount of the large air and move around the area that has low atmospheric pressure. The cyclone can cause the large disturbances to the living organisms.

The cyclone formation occurs at the low polar vertices. The two main types of front are related to the cyclone. The warm front first form for the air movement. This warm front is later replaced by the formation of the cold front of that cyclone.

Thus, the correct answer is option (3).

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.
