What is cold frontal zone?
A cold frontal zone, more commonly called a cold front, is a weather feature in which a cooler air mass pushes into and displaces a warmer one. Since the cooler air mass is denser it forces the warmer one upwards. Depending on conditions, a cold front may produce rain, snow, or thunderstorm, some of which may be severe. The air masses don't need to be warm and cold, but simply need to have notably different temperatures. For example a relatively cold air mass can be replaced by a colder one e.g. temperatures go from the 40s to the 20s), or a hot air mass may be replaced by one that is simply warm (e.g. temperatures drop from the 90s to the 70s).
What atmospheric condition causes a cold front?
When colder air advances toward warm air. The cold air wedges under the warm air like a plow. As the warm is lifted it cools and water vapor condenses forming clouds
Why does cold air make helium balloons collapse when you take them outside?
Cold air molecules move slowly, while hot air molecules move quickly. That's why cold air contracts, weighs less, and go down, while warm air expands, gets lighter, and go up. The cold air inside a helium balloon would contract and make the balloon collapse. Otherwise, there would be a vacuum in the balloon.
Do convection currents push warm air down and cold air up?
Warm air naturally goes up/rises and cold air has to make a current where it can go until it reaches a warm current which is under the warm air.
Why does Cold air normally go under warm air?
It's heavier. Warming gases makes them less dense. That is why hot air balloons work.
Why a flame goes upward?
The gases produced during the process of burning are hot. Hot air is lighter than the cold air. So the flames go upwards.
What is the direction of warm air and cold air?
cold air go up hot air go down.
Why do your glasses fog when go from the cold outside to a warm house?
When you are outside in the cold your glasses become cold. Because the air within buildings tends to be more humid than the air outdoors when the outdoor temperature is low, upon entering the house the water vapour in the air changes state from gas to liquid on the cold surface of your glasses. This results in your glasses fogging.
How much does it cost to go in a hot air balloon?
From £69 upwards.
Why the Mount Everest is cold?
Mount Everest is cold because of the altitude it stands at. The higher you go upwards the colder it gets.
Does the current of a tornado go up or down?
The air in a tornado spirals upwards.
Where does cold air from the poles go?
At the poles, cold air sinks. Simple
What happens if your density is lighter than the density of air?
you will start to float upwards in the atmosphere. The density of air decreases as you go higher in the atmosphere. You will stop going upwards when you reach a height where the air density is the same as your density.
Why does the cold air normally go under the warm air?
Cold air is denser thus heavier.
What will happen when a cold material interacts with a hot material?
The heat will transfer from the hot material to the cold material. Heat tends to go where it is not.
Why is it better to launch a hot air balloon on a cold day?
it is better ot launch a hot air balloon on a cold day than on a warm day because the air rises in the atmosphere therefore if you were to go for a cold day you would go very high but if you were to go a ride on a hot day the hot air balloon wont go as high as on the cold day .
Where does the warm air go after moving over a cold mass?
It keeps moving forward or moves with the cold air it depends
