How do orographic lifting and frontal wedging act to force air to rise?
Wiki User
∙ 7y ago
Orographic lifting: mountains bock air flow and the air is forced upward this usually causes clouds and rain on the windward side of the mountain and less rain on the leeward side.
Frontal wedging: warm air and cold air collide, since warm air is less dense it is wedged upward. This causes a front that's usually rain.

What happens during ice wedging?
when water freezes, it expands. when water freezes in cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart.
How does orographic precipitation occur?
warm moist air is force to rise over a mountain range, as the air moves up it will expand, cools and condenses then precipitation will occur.This is clearly seen in the eastern part of South Africa
How does ice wedging cause mechanical weathering of racks?
If rain water seeps into cracks in rocks, and becomes frozen, the water turns to ice. As the ice expands it can force the cracks wider, even splitting the rock in two.
What are 3 requirements for thunderstorms to form?
Three basic ingredients are required for a thunderstorm to form: moisture, rising/unstable air, and a lifting mechanism to force this rising air higher and faster.
How the frozen water between cracked rocks causes the cracks to widen?
Ice wedging
What does free and forced convection mean?
Forced convection is when air ascends as a result of another force, such as the actions of fronts, orographic lifting, or converging wind. Free convection is caused by a factor such as intense heating of the Earth's surface, which warms air and causes it to rise.
How much force exert when lifting an object?
a force of depend on mass
Ice wedging occurs because a given amount of ice has a volume?
Volume increase which exerts force.
Would frost wedging me more effective in cool high desert areas or where the subsoil is permanently frozen?
It is the feeze/thaw cycle that makes frost wedging really effective as an erosive force. Desert areas that are warm during the day and freezing at night experience more wedging than permafrost areas.
The lifting force on an airplane's wing does what?
increases with speed
How much force does one exert when lifting an object?
The force would be the weight of the object.
A weightlifter lifting a heavy weight uses?
Uses force
What is an example of muscular force?
lifting any heavy material
Is a lifting force necessary to form a thunderstorm?
Yes.Three basic ingredients are required for a thunderstorm to form: moisture, rising/unstable air, and a lifting mechanism to force this rising air higher and faster.
Is lifting a feather work?
Yes, yes it is. Even though it may nt be heavy, the feather has weight and your hand lifting it is the force.
Can an employer force heavy lifting if a doctor restricted it?
No they can not if you have a letter from doctor
What does the lifting force on an airplane wing do?
increases with speed
