What happens when warm air rises at the equator and cold air sinks at the poles?
Air rises at the equator and sinks at the poles, creating a single convection cell in each hemisphere. The prevailing winds moving over the Earth's surface blow from the poles towards the equator in both hemispheres (Modified by PW from globe image by Location_of_Cape_Verde_in_the_globe.
What is it called when warm air rises and cold air sinks?
Convection. The rising of warm air is how heat (or energy) is transferred throughout our atmosphere . This process is called convection , and the rising of warm air and sinking of cold air is called a convection current. These convection currents can also be seen in a liquid, like a pot of boiling water on your stove.

Why does warm air rise and cold air sink Quizizz?
As cool air warms due to the conduction of the land, it rises, and as the warm air cools down, it sinks creating a breeze. Q. Which of the following global winds blows across the United States of America?
What is being formed when cold air sinks?
The result is condensation/precipitation. Cold air sinks. Sinking air compresses and heats. As air sinks, air pressure at the surface is raised.
What does the Coriolis effect cause?
the result of Earth's rotation on weather patterns and ocean currents. The Coriolis effect makes storms swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere. force that explains the paths of objects on rotating bodies.
What happens to the rising warm air at the equator?
Cold air, being more dense, sinks and hot air, being less dense, rises. Consequently, the rising warm air at the equator becomes even less dense as it rises and its pressure decreases. An area of low pressure, therefore, exists over the equator.
What is formed when cold air sinks?
The result is condensation/precipitation. Cold air sinks. Sinking air compresses and heats. As air sinks, air pressure at the surface is raised.
What type of energy is hot air rises and cool air sinks creating winds convection?
Natural convection is caused by density differences. Hot air rises because it is less dense than cold air, so air will rise above a heater and sink near a cold window. Forced convection refers to fluids being pushed around by outside forces.
What is it called when warm air expands and rises?
Denser air exerts a higher pressure than less dense air. Denser air flows toward the less dense air just like the clay! This flow of air is called WIND! Air that moves horizontally is called wind. Air that rises is called an updraft.
When warm air rises what does it create?
Warm air rises, creating a low pressure region, and cool air sinks, creating a high pressure zone. Air flowing from areas of high pressure to low pressure creates winds.
What happens to winds at the equator as a result of the Coriolis effect?
Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) as they move northward.
What is the Coriolis effect short answer?
The Short Answer: Put simply, the Coriolis Effect makes things (like planes or currents of air) traveling long distances around Earth appear to move at a curve as opposed to a straight line.
Does warm air sink at the equator?
In the tropics, near the equator, warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles. Air that rose just north of the equator flows north.
What is conduction and convection?
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.
How does the air from the equator interact with the air from the poles?
The air that rises at the equator does not flow directly to the poles. Due to the rotation of the earth, there is a build up of air at about 30° north latitude. (The same phenomenon occurs in the Southern Hemisphere). Some of the air sinks, causing a belt of high-pressure at this latitude.
What happens to winds at the equator as a result of the Coriolis effect quizlet?
It is caused by the Earth spinning on its axis. The Earth spins fastest at the equator, and slowest near the poles. Due to coriolis effect, cold air from the poles moving toward the equator are deflected toward the west.
What is the impact of Coriolis force and latent heat on the development of the tropical cyclones?
The Coriolis Effect and Cyclones Earth rotates toward the east and this rotation causes fluids, such as air and currents, to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Cyclones can form in areas of low pressure.
What is Coriolis component of acceleration in polar coordinate system?
Definition of Coriolis acceleration: Coriolis acceleration is the acceleration due to the rotation of the earth, experienced by particles (water parcels, for example) moving along the earth's surface. Ocean currents are influenced by Coriolis acceleration.
Why does the air sinks in the poles?
Atmospheric Circulation. Differential heating of the Earth's surface results in equatorial regions receiving more heat than the poles. As air is warmed at the equator it becomes less dense and rises, while at the poles the cold air is denser and sinks.
What is the difference between thermal radiation thermal conduction and thermal convection?
While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.
What is conduction convection and radiation Quora?
Conduction usually occurs in solids, where atoms cannot move freely. Hence, they use neighbor interactions to transfer energy. Convection requires a displacement of particles. Thus, it takes place in fluids where molecules are free to move. Radiation can transfer energy in vacuum and without displacement of the source.
What is found at the boundary between the warm air from the equator and the cold air from the poles?
The polar front Mid-latitudes: 30 to 60 Degrees Latitude The polar front is a boundary between the warm, tropical air and the cold, polar air. This front is strongest and farthest south during the cold winter months.
Why does the air at the equator move toward the poles?
This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises.
What happens to the Coriolis effect at the equator?
The Earth spins on its axis from west to east. The Coriolis force, therefore, acts in a north-south direction. The Coriolis force is zero at the Equator.
What is the impact of Coriolis force and latent heat on the development of tropical cyclones Brainly?
The force experienced will be perpendicular to the earth's rotation axis and direction of motion. In the northern hemisphere, this Coriolis force will divert the motion to the right and in the southern hemisphere, towards the left. Cyclones originate in areas with low pressure.
What is Coriolis component of acceleration derive the relation for its magnitude & show the directions?
The Coriolis acceleration is then given by: du/dt = f v, ; dv/dt = – fu, ; f=2 Omega sin phi . The Coriolis acceleration can be derived in a more intuitive way if we consider fluid velocities (u,v) much smaller than the earth's surface rotation velocity U = R Omega cos phi.
What is meant by Coriolis component of acceleration in which case does it occur How is its direction determined?
Coriolis component of acceleration exists when there is a sliding motion of a slider which is sliding on a link which itself is rotating. In the case of the shaper, the quick return mechanism is used which has slider sliding on the rotating link. So the Coriolis component of acceleration exists.
When warm air rises at the equator what happens to the water that rises with it?
The water content of air roughly doubles with every 10o C increase in temperature. So the air rising at the equator is warm and full of water vapor; as it rises into the upper atmosphere it cools, and the cool air can no longer hold as much water vapor, so the water condenses and forms rain.
Which method of thermal energy transfer occurs in a solid by means of atomic and molecular vibrations within the material?
Which method of thermal energy transfer occurs in a solid by means of atomic and molecular vibrations within the material? Heat is transferred by conduction when adjacent atoms vibrate against one another or as electrons move from one atom to another.
