Why do winds spiral towards the center of the hurricane?
Winds spiral towards the center of a hurricane due to the Coriolis effect, which is caused by the rotation of the Earth. As air rushes in towards the low-pressure center of the storm, the Coriolis effect deflects the moving air to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating a spiraling motion.
Does Convergence of air at the surface creates an inward and upward motion of wind?
Yes, convergence of air at the surface leads to an inward and upward motion of wind. As air masses come together, they are forced to rise, which can create low-pressure areas. This upward motion is essential for cloud formation and precipitation, as the rising air cools and condenses. Overall, surface convergence is a key factor in the development of weather systems and storms.
When air at the surface diverges airflow above does what?
When air at the surface diverges, the airflow above typically converges. This process occurs due to the conservation of mass in the atmosphere; as air spreads out horizontally at the surface, it creates a vacuum that draws in air from above, leading to upward vertical motion. This upward movement can enhance cloud formation and precipitation, particularly in areas of low pressure.
What stream patter is developed only on growing mountains like volcanoes or where the land surface is tectonically doming upward?
A radial drainage pattern is developed on growing mountains like volcanoes or where the land surface is tectonically doming upward. In this pattern, streams flow outward in all directions like the spokes of a wheel, converging at the peak or center of the domed land surface.
What happens when the center of gravity is behind the center of pressure?
With the CG ahead of CP (aka CL), the downward force on the tail creates an upward pitching moment which is opposite of the downward pitching moment caused by the upward force at the CP--these are stabilizing forces. But notice what happens when the CG is behind the CP--both forces now create an upward pitching moment around the CG but there is no counterbalancing downward pitching moment created to stabilize the aircraft.

What is a force that pushes the heated rock upward?
The force that pushes heated rock upward is typically convection currents in the mantle. As rock near the Earth's core heats up, it becomes less dense and rises towards the surface. This movement creates pressure that pushes the rock upward.
When warm air moves upward in a thunderhead it creates a zone of?
When warm air moves upward in a thunderhead, it creates a zone of low pressure at the surface due to the rising air and the removal of mass. This low-pressure zone can lead to the development of strong winds and instability within the thunderstorm cell.
How do tornadoes suck stuff up?
The convection of relatively warm air creates a circular, upward movement, causing a low pressure zone (partial vacuum). Air moves from areas of high pressure to areas of low pressure, like the center of the hurricane.
How is a hurricane similar to a giant chimney?
A hurricane and a giant chimney both involve the movement of air. In a hurricane, warm air rises and creates a low-pressure system that draws in more air, forming a cyclone. Similarly, a giant chimney has a structure that allows hot air to rise and create a strong upward draft, similar to the circulation pattern in a hurricane.
When warm air moves upward in a thunderhead it creates a zone of what?
warm air

How does ship stay afloat?
The ship floats because of its large volume which displaces an amount of water that is more than its weight. That creates an upward force called buoyant force which keeps the ship on the surface.
When you see miso granules rising to the surface is soup liquid moving upward as well or just the granules?
When miso granules rise to the surface of the soup, it indicates that the liquid is also moving upward, as the granules are less dense than the surrounding soup. This upward movement of liquid occurs as the heat from the soup creates convection currents, causing both the liquid and the miso to rise. The granules may appear to float independently, but they are part of the overall movement of the soup.
How does buoyancy help a submerging float?
Buoyancy is the upward force exerted by a fluid that helps to support or lift an object placed in it. When a submerged object such as a float experiences buoyancy, it creates an upward force that counteracts the downward force of gravity, allowing the object to float or maintain its position at the surface of the fluid.
Why does a solid needle placed horizontally on the surface of the water float?
The surface tension of water creates a layer that the needle rests on, despite being denser than water. The needle's weight is dispersed over a large enough area that it balances the upward force of surface tension. This allows the needle to remain afloat on the water's surface.
Why does a tornado cause low pressure areas?
Air in a tornado is rapidly drawn upward. This creates low pressure as more air rushes in to replace it. However this can ever completely fill the pressure deficit until the upward movement stops.
