Final answer:
A pressure system that rotates counter-clockwise and inward is a Low-pressure system, such as a hurricane, affected by the Coriolis force in the Northern Hemisphere.
Step-by-step explanation:
The pressure system that rotates counter-clockwise and inward is known as a Low-pressure system. In the Northern Hemisphere, the Coriolis force causes this rotation, which is a prominent feature of weather systems such as hurricanes. These low-pressure systems are associated with rising air, which leads to cooling, cloud formation, and often, precipitation.
For example, hurricanes, which are a type of tropical cyclone, rotate counter-clockwise in the Northern Hemisphere because of the Coriolis force. This inward and counter-clockwise flow towards the low-pressure center results in the storm's spiral shape. High-pressure systems, conversely, have air that flows outward and rotates clockwise in the Northern Hemisphere.
