What it is called when hot air goes and cold air goes down?
This process is called convection. Hot air rises because it is less dense than cold air, creating a cycle where hot air goes up and cold air goes down, creating air currents.
What is it called when a warm air mass catches up with a cold air mas?
When a warm air mass catches up with a cold air mass, it is known as an occluded front. At this point, the warm air mass is forced aloft as the faster-moving cold front overtakes the slower-moving warm front. This results in cooler temperatures and often precipitation.
What is a warm air mass advancing under a cold air mass called?
A warm air mass advancing under a cold air mass is called an occluded front. This occurs when a fast-moving cold front catches up to a slow-moving warm front, lifting the warm air off the ground. The mixing of air masses can lead to cloud formation and precipitation.
What is the name for vertically rising or sinking air?
Rising and sinking air is called up draft and down draft, respectively.
Does moving air always have more power than air is not moving?
Moving air can have more power than still air, as the kinetic energy generated by the movement of air molecules can create force. However, the power of moving air will depend on factors like velocity and volume of air movement. Still air can also have power in certain situations, such as in confined spaces where pressure differentials can lead to airflow.
What is a warm air stream moving up and a cool air stream moving down in a circulating fashion?
It is a convection current.
Move head up and down?
When you are moving your head up and down it is called duck
What is it called when pistons are moving up and down.?
Reciprocation
What is the instrument that looks like a whistle but as a stick in the end that you move up and down called?
That instrument is called a slide whistle. It produces sound by varying the length of the air column inside the whistle by moving the slide up and down.
What are horizontal movement of air?
What is Horizontal movement of air resulting from local changes in temperature
What makes bubbles break?
what makes bubbles brake is the presur of the air moving up and the air presur moving down compackting the bubble airgo making it pop.
How birds move?
Birds fly in the air by pushing their chest muscles and moving their wings up and down.
What causes lift?
lift is when air is blown at a moving object and the shape of the object pushes it down and itself up as an example when a plane moves down the runway, the air is pushed down by the shape of the wings
How can you check the breathing of a person?
by the stomach moving up and down or you can feel the air through the mouth wich is coming out
What are all the forces acting on a moving balloon?
Gravity is pulling everything down. The hot air in the balloon is less dense than the surrounding air, so the air forces it up through what is called buoyancy. Any air movement will shove the balloon in the direction that air is moving. The balloon will be carried along 'cause there's nothing to stop the air from doing that. Just think about what is happening and it will lock in. Gravity, the wind (moving air) and the conversion of chemical energy in fuel into thermal energy to heat the air in the balloon and give it lift through buoyancy. Simple and easy physics.
What are some signs of life?
Breathing (feel or hear air movement) , chest moving up and down, and body movement.
