The conveyor belt model: a. looks at cyclones in two dimensions. b. has less explanatory power than does the cyclogenesis model. c. does not account for the comma-shaped cloud pattern often associated with cyclones. d. focuses on three major flows of air.

d. focuses on three major flows of air

Explanation:

The conveyor belt model is a three dimensional way of viewing cyclones. It shows the upper flow of three air streams: the warm, the cold and the dry air streams through the life cycle of a cyclone.

This model it is a development on older illustrative models such as the Bergen model by providing information about upper air interactions as well as clouds and precipitation associated with cyclones.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
