Answer:
Mid latitude cyclone are low pressure regional cyclone system formed in 30 to 55 N or S. In this region continental polar and tropical air masses collide to form fronts. Fronts are the boundary between two air masses. This front pushes the warm air to the north and cold air to the south and generating a clockwise rotation. Cyclone starts to form from southwest and reaches mature stage to form a well developed cold front and warm front.This cyclone become weak, both cold and warm front merge as occluded front, this causes the snow and poor weather condition in northeast US, same time southwest is the formation zone, so mild temperature.

Answer:
Karst topography is formed from soluble rocks with many features that create crevices that channel or funnel the surface water into the ground and aquifers below. This can lead to contamination of the water quality in aquifers.
Explanation:
Karst topography refers to the topography formed from soluble rocks such as limestone, dolomite, and gypsum. The topography evolves as the soluble rocks are exposed to wind, sun, and precipitation that erodes the rock materials and creates crevices and the groundwater is channeled away from the surface, inhibiting the formation of lakes and reserves of water at the surface. When these sorts of rocks begin to dissolve caves and crevices and other forms of underground drainage. Five topographic features a geologist might find are solutions flutes and limestone pavement, cenotes, funnel-shaped sinkholes, and reappearing streams.
The surface hazards associated with karst topography are sinkholes as well as other topographic hazards such as subsidence and slope movements. There is a lot of surface water and groundwater interaction in a landscape with karst typography and so aquifers are susceptible to contamination from pollution and the use of fertilizers and chemicals at a higher rate than other topographies. Urban areas and areas where there is a lot of animal husbandry are especially vulnerable to aquifer contamination.
