Describe how local and global wind patterns can lead to cyclonic storms such as tornadoes and hurricanes.

Cyclonic storms are caused when large air masses of different temperature and densities meet. As the warmer air mass of lower density rises and the cooler air descents, a weather front is formed. Coriolis effect causes the front to start spinning to form a funnel. In a tropical storm, the biggest ‘fuel’ is water vapor from the oceans. As the water vapor rises and condenses, the water releases latent heat and warms the surrounding air. This causes a low-pressure system and cooler air masses begin to move to the region of low pressure as the warm air ascends. The spiraling beigns and a tropical storm is formed.

The open ocean begins at the low-tide mark and extends to the end of the continental shelf

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
